+From: Anthony G. Basile <blueness@gentoo.org>
+
+This patch adds support for a restricted user-controlled namespace on
+tmpfs filesystem used to house PaX flags. The namespace must be of the
+form user.pax.* and its value cannot exceed a size of 8 bytes.
+
+This is needed even on all Gentoo systems so that XATTR_PAX flags
+are preserved for users who might build packages using portage on
+a tmpfs system with a non-hardened kernel and then switch to a
+hardened kernel with XATTR_PAX enabled.
+
+The namespace is added to any user with Extended Attribute support
+enabled for tmpfs. Users who do not enable xattrs will not have
+the XATTR_PAX flags preserved.

+This workarounds are causing hangs, because I missed the fact that it

+ Processor family --->
+
+With the release of gcc 11.1 and clang 12.0, several generic 64-bit levels are
+offered which are good for supported Intel or AMD CPUs:

+• x86-64-v4
+
+Users of glibc 2.33 and above can see which level is supported by current
+hardware by running:
+ /lib/ld-linux-x86-64.so.2 --help | grep supported
+
+Alternatively, compare the flags from /proc/cpuinfo to this list.[1]

+
+It also offers to compile passing the 'native' option which, "selects the CPU
+to generate code for at compilation time by determining the processor type of
+the compiling machine. Using -march=native enables all instruction subsets
+supported by the local machine and will produce code optimized for the local
+machine under the constraints of the selected instruction set."[2]
+
+Users of Intel CPUs should select the 'Intel-Native' option and users of AMD
+CPUs should select the 'AMD-Native' option.
+
+MINOR NOTES RELATING TO INTEL ATOM PROCESSORS
+This patch also changes -march=atom to -march=bonnell in accordance with the
+gcc v4.9 changes. Upstream is using the deprecated -match=atom flags when I
+believe it should use the newer -march=bonnell flag for atom processors.[3]
+
+It is not recommended to compile on Atom-CPUs with the 'native' option.[4] The
+recommendation is to use the 'atom' option instead.
+
+BENEFITS
+Small but real speed increases are measurable using a make endpoint comparing
+a generic kernel to one built with one of the respective microarchs.

+
+It doesn't guarantee the mt7921e gets started with ASPM L0 after each
+machine reboot on every platform.
+
+If mt7921e gets started with not ASPM L0, it would be possible that the
+driver encounters time to time failure in mt7921_pci_probe, like a
+weird chip identifier is read
+
+[ 215.514503] mt7921e 0000:05:00.0: ASIC revision: feed0000
+[ 216.604741] mt7921e: probe of 0000:05:00.0 failed with error -110
+
+or failing to init hardware because the driver is not allowed to access the
+register until the device is in ASPM L0 state. So, we call
+__mt7921e_mcu_drv_pmctrl in early mt7921_pci_probe to force the device
+to bring back to the L0 state for we can safely access registers in any
+case.
+
+In the patch, we move all functions from dma.c to pci.c and register mt76
+bus operation earilier, that is the __mt7921e_mcu_drv_pmctrl depends on.

+- * Reqs with at_head or passthrough flags set are to be put
+- * directly into dispatch list. Additional case for putting rq
+- * directly into the dispatch queue: the only active
+- * bfq_queues are bfqq and either its waker bfq_queue or one
+- * of its woken bfq_queues. The rationale behind this
+- * additional condition is as follows:
+- * - consider a bfq_queue, say Q1, detected as a waker of
+- * another bfq_queue, say Q2
+- * - by definition of a waker, Q1 blocks the I/O of Q2, i.e.,
+- * some I/O of Q1 needs to be completed for new I/O of Q2
+- * to arrive. A notable example of waker is journald
+- * - so, Q1 and Q2 are in any respect the queues of two
+- * cooperating processes (or of two cooperating sets of
+- * processes): the goal of Q1's I/O is doing what needs to
+- * be done so that new Q2's I/O can finally be
+- * issued. Therefore, if the service of Q1's I/O is delayed,
+- * then Q2's I/O is delayed too. Conversely, if Q2's I/O is
+- * delayed, the goal of Q1's I/O is hindered.
+- * - as a consequence, if some I/O of Q1/Q2 arrives while
+- * Q2/Q1 is the only queue in service, there is absolutely
+- * no point in delaying the service of such an I/O. The
+- * only possible result is a throughput loss
+- * - so, when the above condition holds, the best option is to
+- * have the new I/O dispatched as soon as possible
+- * - the most effective and efficient way to attain the above
+- * goal is to put the new I/O directly in the dispatch
+- * list
+- * - as an additional restriction, Q1 and Q2 must be the only
+- * busy queues for this commit to put the I/O of Q2/Q1 in
+- * the dispatch list. This is necessary, because, if also
+- * other queues are waiting for service, then putting new
+- * I/O directly in the dispatch list may evidently cause a
+- * violation of service guarantees for the other queues

++ * PCIe topology exported by mvebu hw is quite complicated. In
++ * reality has something like N fully independent host bridges
++ * where each host bridge has one PCIe Root Port (which acts as
++ * PCI Bridge device). Each host bridge has its own independent
++ * internal registers, independent access to PCI config space,
++ * independent interrupt lines, independent window and memory
++ * access configuration. But additionally there is some kind of
++ * peer-to-peer support between PCIe devices behind different
++ * host bridges limited just to forwarding of memory and I/O
++ * transactions (forwarding of error messages and config cycles
++ * is not supported). So we could say there are N independent
++ * PCIe Root Complexes.
++ *
++ * For this kind of setup DT should have been structured into
++ * N independent PCIe controllers / host bridges. But instead
++ * structure in past was defined to put PCIe Root Ports of all
++ * host bridges into one bus zero, like in classic multi-port
++ * Root Complex setup with just one host bridge.
++ *
++ * This means that pci-mvebu.c driver provides "virtual" bus 0
++ * on which registers all PCIe Root Ports (PCI Bridge devices)
++ * specified in DT by their BDF addresses and virtually routes
++ * PCI config access of each PCI bridge device to specific PCIe
++ * host bridge.
++ *
++ * Normally PCI Bridge should choose between Type 0 and Type 1
++ * config requests based on primary and secondary bus numbers
++ * configured on the bridge itself. But because mvebu PCI Bridge
++ * does not have registers for primary and secondary bus numbers
++ * in its config space, it determinates type of config requests
++ * via its own custom way.
++ *
++ * There are two options how mvebu determinate type of config
++ * request.
++ *
++ * 1. If Secondary Bus Number Enable bit is not set or is not
++ * available (applies for pre-XP PCIe controllers) then Type 0
++ * is used if target bus number equals Local Bus Number (bits
++ * [15:8] in register 0x1a04) and target device number differs
++ * from Local Device Number (bits [20:16] in register 0x1a04).
++ * Type 1 is used if target bus number differs from Local Bus
++ * Number. And when target bus number equals Local Bus Number
++ * and target device equals Local Device Number then request is
++ * routed to Local PCI Bridge (PCIe Root Port).
++ *
++ * 2. If Secondary Bus Number Enable bit is set (bit 7 in
++ * register 0x1a2c) then mvebu hw determinate type of config
++ * request like compliant PCI Bridge based on primary bus number
++ * which is configured via Local Bus Number (bits [15:8] in
++ * register 0x1a04) and secondary bus number which is configured
++ * via Secondary Bus Number (bits [7:0] in register 0x1a2c).
++ * Local PCI Bridge (PCIe Root Port) is available on primary bus
++ * as device with Local Device Number (bits [20:16] in register
++ * 0x1a04).
++ *
++ * Secondary Bus Number Enable bit is disabled by default and
++ * option 2. is not available on pre-XP PCIe controllers. Hence
++ * this driver always use option 1.
++ *
++ * Basically it means that primary and secondary buses shares
++ * one virtual number configured via Local Bus Number bits and
++ * Local Device Number bits determinates if accessing primary
++ * or secondary bus. Set Local Device Number to 1 and redirect
++ * all writes of PCI Bridge Secondary Bus Number register to
++ * Local Bus Number (bits [15:8] in register 0x1a04).
++ *
++ * So when accessing devices on buses behind secondary bus
++ * number it would work correctly. And also when accessing
++ * device 0 at secondary bus number via config space would be
++ * correctly routed to secondary bus. Due to issues described
++ * in mvebu_pcie_setup_hw(), PCI Bridges at primary bus (zero)
++ * are not accessed directly via PCI config space but rarher
++ * indirectly via kernel emulated PCI bridge driver.

+If no firmware was present at all (or, presumably, all of the
+firmware files failed to parse), we end up unbinding by calling
+device_release_driver(), which calls remove(), which then in
+iwlwifi calls iwl_drv_stop(), freeing the 'drv' struct. However
+the new code I added will still erroneously access it after it
+was freed.
+
+Set 'failure=false' in this case to avoid the access, all data

+-Garbage collect fbdev scrolling acceleration
+---------------------------------------------
+-
+-Scroll acceleration has been disabled in fbcon. Now it works as the old
+-SCROLL_REDRAW mode. A ton of code was removed in fbcon.c and the hook bmove was
+-removed from fbcon_ops.
+-Remaining tasks:
+-
+-- a bunch of the hooks in fbcon_ops could be removed or simplified by calling
+- directly instead of the function table (with a switch on p->rotate)
+-
+-- fb_copyarea is unused after this, and can be deleted from all drivers
+-
+-- after that, fb_copyarea can be deleted from fb_ops in include/linux/fb.h as
+- well as cfb_copyarea
+-
+-Note that not all acceleration code can be deleted, since clearing and cursor
+-support is still accelerated, which might be good candidates for further
+-deletion projects.

++/* There are several methods fbcon can use to move text around the screen:
++ *
++ * Operation Pan Wrap
++ *---------------------------------------------
++ * SCROLL_MOVE copyarea No No
++ * SCROLL_PAN_MOVE copyarea Yes No
++ * SCROLL_WRAP_MOVE copyarea No Yes
++ * SCROLL_REDRAW imageblit No No
++ * SCROLL_PAN_REDRAW imageblit Yes No
++ * SCROLL_WRAP_REDRAW imageblit No Yes
++ *
++ * (SCROLL_WRAP_REDRAW is not implemented yet)
++ *
++ * In general, fbcon will choose the best scrolling
++ * method based on the rule below:
++ *
++ * Pan/Wrap > accel imageblit > accel copyarea >
++ * soft imageblit > (soft copyarea)
++ *
++ * Exception to the rule: Pan + accel copyarea is
++ * preferred over Pan + accel imageblit.
++ *
++ * The above is typical for PCI/AGP cards. Unless
++ * overridden, fbcon will never use soft copyarea.
++ *
++ * If you need to override the above rule, set the
++ * appropriate flags in fb_info->flags. For example,
++ * to prefer copyarea over imageblit, set
++ * FBINFO_READS_FAST.
++ *
++ * Other notes:
++ * + use the hardware engine to move the text
++ * (hw-accelerated copyarea() and fillrect())
++ * + use hardware-supported panning on a large virtual screen
++ * + amifb can not only pan, but also wrap the display by N lines
++ * (i.e. visible line i = physical line (i+N) % yres).
++ * + read what's already rendered on the screen and
++ * write it in a different place (this is cfb_copyarea())
++ * + re-render the text to the screen
++ *
++ * Whether to use wrapping or panning can only be figured out at
++ * runtime (when we know whether our font height is a multiple
++ * of the pan/wrap step)

++ This option adds the workaround for ARM Cortex-A510 erratum 2038923.
++
++ Affected Cortex-A510 core might cause an inconsistent view on whether trace is
++ prohibited within the CPU. As a result, the trace buffer or trace buffer state
++ might be corrupted. This happens after TRBE buffer has been enabled by setting
++ TRBLIMITR_EL1.E, followed by just a single context synchronization event before
++ execution changes from a context, in which trace is prohibited to one where it
++ isn't, or vice versa. In these mentioned conditions, the view of whether trace
++ is prohibited is inconsistent between parts of the CPU, and the trace buffer or
++ the trace buffer state might be corrupted.
++
++ Work around this in the driver by preventing an inconsistent view of whether the
++ trace is prohibited or not based on TRBLIMITR_EL1.E by immediately following a
++ change to TRBLIMITR_EL1.E with at least one ISB instruction before an ERET, or

++If a filter is placed on a string pointer ``(char *)`` that does not point

++ help
++ This option adds the workaround for ARM Cortex-A510 erratum 2077057.
++ Affected Cortex-A510 may corrupt SPSR_EL2 when the a step exception is
++ expected, but a Pointer Authentication trap is taken instead. The
++ erratum causes SPSR_EL1 to be copied to SPSR_EL2, which could allow
++ EL1 to cause a return to EL2 with a guest controlled ELR_EL2.
++
++ This can only happen when EL2 is stepping EL1.
++
++ When these conditions occur, the SPSR_EL2 value is unchanged from the
++ previous guest entry, and can be restored from the in-memory copy.
++
++ If unsure, say Y.

++Yet another variant 2 attack vector is for the attacker to poison the
++Branch History Buffer (BHB) to speculatively steer an indirect branch
++to a specific Branch Target Buffer (BTB) entry, even if the entry isn't
++associated with the source address of the indirect branch. Specifically,
++the BHB might be shared across privilege levels even in the presence of
++Enhanced IBRS.
++
++Currently the only known real-world BHB attack vector is via
++unprivileged eBPF. Therefore, it's highly recommended to not enable
++unprivileged eBPF, especially when eIBRS is used (without retpolines).
++For a full mitigation against BHB attacks, it's recommended to use
++retpolines (or eIBRS combined with retpolines).

+Subject: Revert "swiotlb: rework "fix info leak with DMA_FROM_DEVICE""
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Linus Torvalds <torvalds@linux-foundation.org>
+
+commit bddac7c1e02ba47f0570e494c9289acea3062cc1 upstream.
+
+This reverts commit aa6f8dcbab473f3a3c7454b74caa46d36cdc5d13.
+
+It turns out this breaks at least the ath9k wireless driver, and
+possibly others.
+
+What the ath9k driver does on packet receive is to set up the DMA
+transfer with:
+
+ int ath_rx_init(..)
+ ..
+ bf->bf_buf_addr = dma_map_single(sc->dev, skb->data,
+ common->rx_bufsize,
+ DMA_FROM_DEVICE);
+
+and then the receive logic (through ath_rx_tasklet()) will fetch
+incoming packets
+
+ static bool ath_edma_get_buffers(..)
+ ..
+ dma_sync_single_for_cpu(sc->dev, bf->bf_buf_addr,
+ common->rx_bufsize, DMA_FROM_DEVICE);
+
+ ret = ath9k_hw_process_rxdesc_edma(ah, rs, skb->data);
+ if (ret == -EINPROGRESS) {
+ /*let device gain the buffer again*/
+ dma_sync_single_for_device(sc->dev, bf->bf_buf_addr,
+ common->rx_bufsize, DMA_FROM_DEVICE);
+ return false;
+ }
+
+and it's worth noting how that first DMA sync:
+
+ dma_sync_single_for_cpu(..DMA_FROM_DEVICE);
+
+is there to make sure the CPU can read the DMA buffer (possibly by
+copying it from the bounce buffer area, or by doing some cache flush).
+The iommu correctly turns that into a "copy from bounce bufer" so that
+the driver can look at the state of the packets.
+
+In the meantime, the device may continue to write to the DMA buffer, but
+we at least have a snapshot of the state due to that first DMA sync.
+
+But that _second_ DMA sync:
+
+ dma_sync_single_for_device(..DMA_FROM_DEVICE);
+
+is telling the DMA mapping that the CPU wasn't interested in the area
+because the packet wasn't there. In the case of a DMA bounce buffer,
+that is a no-op.
+
+Note how it's not a sync for the CPU (the "for_device()" part), and it's
+not a sync for data written by the CPU (the "DMA_FROM_DEVICE" part).
+
+Or rather, it _should_ be a no-op. That's what commit aa6f8dcbab47
+broke: it made the code bounce the buffer unconditionally, and changed
+the DMA_FROM_DEVICE to just unconditionally and illogically be
+DMA_TO_DEVICE.
+
+[ Side note: purely within the confines of the swiotlb driver it wasn't
+ entirely illogical: The reason it did that odd DMA_FROM_DEVICE ->
+ DMA_TO_DEVICE conversion thing is because inside the swiotlb driver,
+ it uses just a swiotlb_bounce() helper that doesn't care about the
+ whole distinction of who the sync is for - only which direction to
+ bounce.
+
+ So it took the "sync for device" to mean that the CPU must have been
+ the one writing, and thought it meant DMA_TO_DEVICE. ]
+
+Also note how the commentary in that commit was wrong, probably due to
+that whole confusion, claiming that the commit makes the swiotlb code
+
+ "bounce unconditionally (that is, also
+ when dir == DMA_TO_DEVICE) in order do avoid synchronising back stale
+ data from the swiotlb buffer"
+
+which is nonsensical for two reasons:
+
+ - that "also when dir == DMA_TO_DEVICE" is nonsensical, as that was
+ exactly when it always did - and should do - the bounce.
+
+ - since this is a sync for the device (not for the CPU), we're clearly
+ fundamentally not coping back stale data from the bounce buffers at
+ all, because we'd be copying *to* the bounce buffers.
+
+So that commit was just very confused. It confused the direction of the
+synchronization (to the device, not the cpu) with the direction of the
+DMA (from the device).

+-/* Realtek Simple Management Interface (SMI) driver
+- * It can be discussed how "simple" this interface is.
+- *
+- * The SMI protocol piggy-backs the MDIO MDC and MDIO signals levels
+- * but the protocol is not MDIO at all. Instead it is a Realtek
+- * pecularity that need to bit-bang the lines in a special way to
+- * communicate with the switch.
+- *
+- * ASICs we intend to support with this driver:
+- *
+- * RTL8366 - The original version, apparently
+- * RTL8369 - Similar enough to have the same datsheet as RTL8366
+- * RTL8366RB - Probably reads out "RTL8366 revision B", has a quite
+- * different register layout from the other two
+- * RTL8366S - Is this "RTL8366 super"?
+- * RTL8367 - Has an OpenWRT driver as well
+- * RTL8368S - Seems to be an alternative name for RTL8366RB
+- * RTL8370 - Also uses SMI

++/* Realtek Simple Management Interface (SMI) driver
++ * It can be discussed how "simple" this interface is.
++ *
++ * The SMI protocol piggy-backs the MDIO MDC and MDIO signals levels
++ * but the protocol is not MDIO at all. Instead it is a Realtek
++ * pecularity that need to bit-bang the lines in a special way to
++ * communicate with the switch.
++ *
++ * ASICs we intend to support with this driver:
++ *
++ * RTL8366 - The original version, apparently
++ * RTL8369 - Similar enough to have the same datsheet as RTL8366
++ * RTL8366RB - Probably reads out "RTL8366 revision B", has a quite
++ * different register layout from the other two
++ * RTL8366S - Is this "RTL8366 super"?
++ * RTL8367 - Has an OpenWRT driver as well
++ * RTL8368S - Seems to be an alternative name for RTL8366RB
++ * RTL8370 - Also uses SMI

++ *
++ * The RTL8365MB-VC is a 4+1 port 10/100/1000M switch controller. It includes 4
++ * integrated PHYs for the user facing ports, and an extension interface which
++ * can be connected to the CPU - or another PHY - via either MII, RMII, or
++ * RGMII. The switch is configured via the Realtek Simple Management Interface
++ * (SMI), which uses the MDIO/MDC lines.
++ *
++ * Below is a simplified block diagram of the chip and its relevant interfaces.
++ *
++ * .-----------------------------------.

++ * GPIO <--------------> Reset ~~~~~~~~~~~~~~ |

++ * Interrupt <----------> Link UP/DOWN events |
++ * controller | |
++ * '-----------------------------------'
++ *
++ * The driver uses DSA to integrate the 4 user and 1 extension ports into the
++ * kernel. Netdevices are created for the user ports, as are PHY devices for
++ * their integrated PHYs. The device tree firmware should also specify the link
++ * partner of the extension port - either via a fixed-link or other phy-handle.
++ * See the device tree bindings for more detailed information. Note that the
++ * driver has only been tested with a fixed-link, but in principle it should not
++ * matter.
++ *
++ * NOTE: Currently, only the RGMII interface is implemented in this driver.
++ *
++ * The interrupt line is asserted on link UP/DOWN events. The driver creates a
++ * custom irqchip to handle this interrupt and demultiplex the events by reading
++ * the status registers via SMI. Interrupts are then propagated to the relevant
++ * PHY device.
++ *
++ * The EEPROM contains initial register values which the chip will read over I2C
++ * upon hardware reset. It is also possible to omit the EEPROM. In both cases,
++ * the driver will manually reprogram some registers using jam tables to reach
++ * an initial state defined by the vendor driver.
++ *
++ * This Linux driver is written based on an OS-agnostic vendor driver from
++ * Realtek. The reference GPL-licensed sources can be found in the OpenWrt
++ * source tree under the name rtl8367c. The vendor driver claims to support a
++ * number of similar switch controllers from Realtek, but the only hardware we
++ * have is the RTL8365MB-VC. Moreover, there does not seem to be any chip under
++ * the name RTL8367C. Although one wishes that the 'C' stood for some kind of
++ * common hardware revision, there exist examples of chips with the suffix -VC
++ * which are explicitly not supported by the rtl8367c driver and which instead
++ * require the rtl8367d vendor driver. With all this uncertainty, the driver has
++ * been modestly named rtl8365mb. Future implementors may wish to rename things
++ * accordingly.
++ *
++ * In the same family of chips, some carry up to 8 user ports and up to 2
++ * extension ports. Where possible this driver tries to make things generic, but
++ * more work must be done to support these configurations. According to
++ * documentation from Realtek, the family should include the following chips:
++ *
++ * - RTL8363NB
++ * - RTL8363NB-VB
++ * - RTL8363SC
++ * - RTL8363SC-VB
++ * - RTL8364NB
++ * - RTL8364NB-VB
++ * - RTL8365MB-VC
++ * - RTL8366SC
++ * - RTL8367RB-VB
++ * - RTL8367SB
++ * - RTL8367S
++ * - RTL8370MB
++ * - RTL8310SR
++ *
++ * Some of the register logic for these additional chips has been skipped over
++ * while implementing this driver. It is therefore not possible to assume that
++ * things will work out-of-the-box for other chips, and a careful review of the
++ * vendor driver may be needed to expand support. The RTL8365MB-VC seems to be
++ * one of the simpler chips.

+- *
+- * The RTL8365MB-VC is a 4+1 port 10/100/1000M switch controller. It includes 4
+- * integrated PHYs for the user facing ports, and an extension interface which
+- * can be connected to the CPU - or another PHY - via either MII, RMII, or
+- * RGMII. The switch is configured via the Realtek Simple Management Interface
+- * (SMI), which uses the MDIO/MDC lines.
+- *
+- * Below is a simplified block diagram of the chip and its relevant interfaces.
+- *

+- * '-----------------------------------'
+- *
+- * The driver uses DSA to integrate the 4 user and 1 extension ports into the
+- * kernel. Netdevices are created for the user ports, as are PHY devices for
+- * their integrated PHYs. The device tree firmware should also specify the link
+- * partner of the extension port - either via a fixed-link or other phy-handle.
+- * See the device tree bindings for more detailed information. Note that the
+- * driver has only been tested with a fixed-link, but in principle it should not
+- * matter.
+- *
+- * NOTE: Currently, only the RGMII interface is implemented in this driver.
+- *
+- * The interrupt line is asserted on link UP/DOWN events. The driver creates a
+- * custom irqchip to handle this interrupt and demultiplex the events by reading
+- * the status registers via SMI. Interrupts are then propagated to the relevant
+- * PHY device.
+- *
+- * The EEPROM contains initial register values which the chip will read over I2C
+- * upon hardware reset. It is also possible to omit the EEPROM. In both cases,
+- * the driver will manually reprogram some registers using jam tables to reach
+- * an initial state defined by the vendor driver.
+- *
+- * This Linux driver is written based on an OS-agnostic vendor driver from
+- * Realtek. The reference GPL-licensed sources can be found in the OpenWrt
+- * source tree under the name rtl8367c. The vendor driver claims to support a
+- * number of similar switch controllers from Realtek, but the only hardware we
+- * have is the RTL8365MB-VC. Moreover, there does not seem to be any chip under
+- * the name RTL8367C. Although one wishes that the 'C' stood for some kind of
+- * common hardware revision, there exist examples of chips with the suffix -VC
+- * which are explicitly not supported by the rtl8367c driver and which instead
+- * require the rtl8367d vendor driver. With all this uncertainty, the driver has
+- * been modestly named rtl8365mb. Future implementors may wish to rename things
+- * accordingly.
+- *
+- * In the same family of chips, some carry up to 8 user ports and up to 2
+- * extension ports. Where possible this driver tries to make things generic, but
+- * more work must be done to support these configurations. According to
+- * documentation from Realtek, the family should include the following chips:
+- *
+- * - RTL8363NB
+- * - RTL8363NB-VB
+- * - RTL8363SC
+- * - RTL8363SC-VB
+- * - RTL8364NB
+- * - RTL8364NB-VB
+- * - RTL8365MB-VC
+- * - RTL8366SC
+- * - RTL8367RB-VB
+- * - RTL8367SB
+- * - RTL8367S
+- * - RTL8370MB
+- * - RTL8310SR
+- *
+- * Some of the register logic for these additional chips has been skipped over
+- * while implementing this driver. It is therefore not possible to assume that
+- * things will work out-of-the-box for other chips, and a careful review of the
+- * vendor driver may be needed to expand support. The RTL8365MB-VC seems to be
+- * one of the simpler chips.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Linus Torvalds <torvalds@linux-foundation.org>
-
-commit bddac7c1e02ba47f0570e494c9289acea3062cc1 upstream.
-
-This reverts commit aa6f8dcbab473f3a3c7454b74caa46d36cdc5d13.
-
-It turns out this breaks at least the ath9k wireless driver, and
-possibly others.
-
-What the ath9k driver does on packet receive is to set up the DMA
-transfer with:
-
- int ath_rx_init(..)
- ..
- bf->bf_buf_addr = dma_map_single(sc->dev, skb->data,
- common->rx_bufsize,
- DMA_FROM_DEVICE);
-
-and then the receive logic (through ath_rx_tasklet()) will fetch
-incoming packets
-
- static bool ath_edma_get_buffers(..)
- ..
- dma_sync_single_for_cpu(sc->dev, bf->bf_buf_addr,
- common->rx_bufsize, DMA_FROM_DEVICE);
-
- ret = ath9k_hw_process_rxdesc_edma(ah, rs, skb->data);
- if (ret == -EINPROGRESS) {
- /*let device gain the buffer again*/
- dma_sync_single_for_device(sc->dev, bf->bf_buf_addr,
- common->rx_bufsize, DMA_FROM_DEVICE);
- return false;
- }
-
-and it's worth noting how that first DMA sync:
-
- dma_sync_single_for_cpu(..DMA_FROM_DEVICE);
-
-is there to make sure the CPU can read the DMA buffer (possibly by
-copying it from the bounce buffer area, or by doing some cache flush).
-The iommu correctly turns that into a "copy from bounce bufer" so that
-the driver can look at the state of the packets.
-
-In the meantime, the device may continue to write to the DMA buffer, but
-we at least have a snapshot of the state due to that first DMA sync.
-
-But that _second_ DMA sync:
-
- dma_sync_single_for_device(..DMA_FROM_DEVICE);
-
-is telling the DMA mapping that the CPU wasn't interested in the area
-because the packet wasn't there. In the case of a DMA bounce buffer,
-that is a no-op.
-
-Note how it's not a sync for the CPU (the "for_device()" part), and it's
-not a sync for data written by the CPU (the "DMA_FROM_DEVICE" part).
-
-Or rather, it _should_ be a no-op. That's what commit aa6f8dcbab47
-broke: it made the code bounce the buffer unconditionally, and changed
-the DMA_FROM_DEVICE to just unconditionally and illogically be
-DMA_TO_DEVICE.
-
-[ Side note: purely within the confines of the swiotlb driver it wasn't
- entirely illogical: The reason it did that odd DMA_FROM_DEVICE ->
- DMA_TO_DEVICE conversion thing is because inside the swiotlb driver,
- it uses just a swiotlb_bounce() helper that doesn't care about the
- whole distinction of who the sync is for - only which direction to
- bounce.
-
- So it took the "sync for device" to mean that the CPU must have been
- the one writing, and thought it meant DMA_TO_DEVICE. ]
-
-Also note how the commentary in that commit was wrong, probably due to
-that whole confusion, claiming that the commit makes the swiotlb code
-
- "bounce unconditionally (that is, also
- when dir == DMA_TO_DEVICE) in order do avoid synchronising back stale
- data from the swiotlb buffer"
-
-which is nonsensical for two reasons:
-
- - that "also when dir == DMA_TO_DEVICE" is nonsensical, as that was
- exactly when it always did - and should do - the bounce.
-
- - since this is a sync for the device (not for the CPU), we're clearly
- fundamentally not coping back stale data from the bounce buffers at
- all, because we'd be copying *to* the bounce buffers.
-
-So that commit was just very confused. It confused the direction of the
-synchronization (to the device, not the cpu) with the direction of the
-DMA (from the device).

-
-It doesn't guarantee the mt7921e gets started with ASPM L0 after each
-machine reboot on every platform.
-
-If mt7921e gets started with not ASPM L0, it would be possible that the
-driver encounters time to time failure in mt7921_pci_probe, like a
-weird chip identifier is read
-
-[ 215.514503] mt7921e 0000:05:00.0: ASIC revision: feed0000
-[ 216.604741] mt7921e: probe of 0000:05:00.0 failed with error -110
-
-or failing to init hardware because the driver is not allowed to access the
-register until the device is in ASPM L0 state. So, we call
-__mt7921e_mcu_drv_pmctrl in early mt7921_pci_probe to force the device
-to bring back to the L0 state for we can safely access registers in any
-case.
-
-In the patch, we move all functions from dma.c to pci.c and register mt76
-bus operation earilier, that is the __mt7921e_mcu_drv_pmctrl depends on.
