[gentoo-dev] New virtual: virtual/pcmcia

[gentoo-dev] New virtual: virtual/pcmcia

Hi,

Starting from linux-2.6.13-rc1 the PCMCIA subsystem has been patched to
exports certain internals to sysfs, which allows using hotplug for
handling insertion/ejection of 16bit PCMCIA cards.

For this to work, a new package called pcmciautils [1] will need to be
added to portage. Therefore, a new virtual/pcmcia (which will default to
sys-apps/pcmcia-cs in base/virtuals for now) will be added as well.

I have had sys-apps/pcmciautils in my portage overlay [2] for quite a
while now, just waiting for the needed functionality to be merged into
Linus' tree.

The linux-mod eclass will be changed to depend on virtual/pcmcia for
pcmcia support. Future ebuilds that just need a PCMCIA card manager
should depend on virtual/pcmcia as well.

If anybody has any objections and/or questions to this new virtual,
please drop me an e-mail.

Sincerely,
Brix

I forgot to mention that the addition of pcmciautils is handled in bug
#84234 [1].

... and it is done.

According to Dominik Brodowski, the author of pcmciautils, Gentoo is the
first distribution to include pcmciautils.

On that note.. Would you mind compiling it one time with a gcc built 
with +boundschecking and then enabling CFLAGS+= -fbounds-checking as a
basic q/a check. Reason being that if nobody has ever included it
anywhere the chances of it being audited are slim to none and
-fbounds-checking helps ferret out alot of common coding mistakes.
gcc-3.4.4 works good for this.

thanks in advance.

A bit late I know, but just for interest sake .. virtuals is usually
used when more than one package usually provides the same compatible
api/tool ... which basically means pcmcia-cs and pcmciautils do the same
thing and cannot be installed together ?  Sorry if my non-pcmcia
cluedup-ness shows ...

Yes, that is correct. pcmciautils will replace pcmcia-cs starting with
linux-2.6.13, and the two can not be installed side-by-side as they have
file collisions (not to mention the fact that they provide the same
functionality).

Sincerely,
Brix

I am still on gcc-3.3.x - will that work for this test?

Yup .. there might just be an bug with bounds-checking that breaks make
jobs .. so if it borks, try with make -j1 ...

I've tested this with CFLAGS+=-fbounds-checking as suggested, and I see
a couple of "cc1: warning: htb stub: bounds checking is not supported"
warnings. Please advice.
