[gentoo-dev] Need ARM/AArch64 test data for cpuid2cpuflags

[Michał Górny]

[-- Attachment #1: Type: text/plain, Size: 735 bytes --]

Hi, everyone.

I've recently (finally!) started adding tests to cpuid2cpuflags.  Tests
are based on mocked syscalls that return arch-specific data read from
text files.  So far I've got x86 and ppc covered, and now I'd like to
add tests for various arm hardware.  Since ARM covers a pretty broad
range of hardware, I'd use as much data as possible, especially from
different ARM generations.

If you have an ARM board and would like to help, please:

wget https://dev.gentoo.org/~mgorny/dist/cpuid2cpuflags-7-dev.tar.bz2
tar -xf cpuid2cpuflags-7-dev.tar.bz2
cd cpuid2cpuflags-7-dev
./configure
make hwcap-dump
./hwcap-dump

and send me the output along with 'uname -m'.  TIA!

I'm sorry but sending it this late, I forgot two more important things:

1. Name of the CPU or the board (i.e. something I can use to name
the test).

2. Output of cpuid2cpuflags, preferably verified against cpuinfo.

Thanks.  This is identical to Beaglebone, so I'm gonna skip it.

Thank you!  Finally something older than v7 ;-).  All old hardware
appreciated to improve test coverage.

Re: [gentoo-dev] Need ARM/AArch64 test data for cpuid2cpuflags

[Matt Turner]

From my original generation SolidRun Cubox:

$ ./hwcap-dump
hwcap:000000000004ead6
hwcap2:0000000000000000
mattst88@cubox ~/cpuid2cpuflags-7-dev $ uname -a
Linux cubox 5.2.7 #11 Wed Aug 7 17:50:03 PDT 2019 armv7l ARMv7

cpuid2cflags says
CPU_FLAGS_ARM: edsp iwmmxt thumb vfp vfpv3 v4 v5 v6 v7 thumb2

/proc/cpuinfo:

I've got an "iwmmxt2" flag on x11-libs/pixman, but I don't think
there's a hwcap bit for it. At least not that I see in
arch/arm/include/uapi/asm/hwcap.h

That's just as well. It's only a very small optimization over iwmmxt.

Maybe there's some other way of inferring it.  For example, 'thumb2'
we're basing on ARM version.

Re: [gentoo-dev] Need ARM/AArch64 test data for cpuid2cpuflags

[James Cloos]

On an odroidc1, I get:

# ./hwcap-dump
hwcap:000000000009b0d7
hwcap2:0000000000000000

# uname -m
armv7l

On an original dragonboard, I get:

# ./hwcap-dump
hwcap:0000000000000087
hwcap2:0000000000000000

# uname -m
aarch64

(Both run gentoo.)

The pi3 says:

hwcap:00000000003fb0d6
hwcap2:0000000000000010
armv7l

I have a couple of cheap arm32 (don't recall manuf) which report:

hwcap:00000000000fb8d7
hwcap2:0000000000000000
armv7l

A c.h.i.p. says:

hwcap:000000000008b0d6
hwcap2:0000000000000000
armv7l

All of my other arm boards are offline.

This one's identical to Compulab Utilite Pro.

Thanks for all the data so far.  I've released v8 with the lot of ARM
tests just now.

If someone's got older hardware (<ARMv7), then I'd really use such
results.  After all, we technically do support ARMv4.

No problem.  Thanks.  I've added the aarch64 boards, the rest are
duplicates of what we have already.

Team, this is going to be a long rambling tale of woe. Sorry in advance.
On arm64 cpuid2cpuflags-8 tells me
  
Pi4_~arm64 /usr/portage # cpuid2cpuflags 
CPU_FLAGS_ARM: edsp neon thumb vfp vfpv3 vfpv4 vfp-d32 crc32 v4 v5 v6 v7 v8 thumb2

but by chance I hit 
[Bug 695854] net-misc/freerdp-2.0.0_rc4 on arm64 - aarch64-unknown-linux-gnu-gcc: error: unrecognized command line option ‘-mfpu=neon’

The 32 bit arm instruction set is optional on arm64.
The 64 bit Raspberry Pis all have it
The Cavium Thunder does not.

It is unlikely that there will ever be a multilib arm64. Only a subset
of arm64 could ever support it, so should we be using CPU_FLAGS_ARM
to cover arm64 too?

There is nothing in the name. Its the content that matters.

On a Pi4 in 64 bit mode, cpuinfo shows
Pi4_~arm64 /usr/portage # cat /proc/cpuinfo 
processor       : 0
BogoMIPS        : 108.00
Features        : fp asimd evtstrm crc32 cpuid
CPU implementer : 0x41
CPU architecture: 8
CPU variant     : 0x0
CPU part        : 0xd08
CPU revision    : 3

In 32 bit mode, the same CPU shows
$ cat pi4_32.txt 
processor	: 0
model name	: ARMv7 Processor rev 3 (v7l)
BogoMIPS	: 108.00
Features	: half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm crc32 
CPU implementer	: 0x41
CPU architecture: 7
CPU variant	: 0x0
CPU part	: 0xd08
CPU revision	: 3


Cavium (64 bit)
arm64-build / # cat /proc/cpuinfo 
processor	: 0
BogoMIPS	: 200.00
Features	: fp asimd evtstrm aes pmull sha1 sha2 crc32
CPU implementer	: 0x43
CPU architecture: 8
CPU variant	: 0x1
CPU part	: 0x0a1
CPU revision	: 1

The Cavium does not have any 32 bit instructions.

From bug 695854, CPU_FLAGS_ARM: neon is not correct on the Cavium.
I suspect that the other 32 bit flags will fail there, as it does not have them
but they might work on the Pi, as it does.

Other than pointing out the problem, I don't know how to test further. 
Guidance welcome.
