So, what is the danger of using these 'disabled' ioctls?
I can't find any reference to 'TCOC* definitions' - what are these ???
A typo of TIOC* or TC*. They are defined in asm-*/ioctls.h.
These are used for syscalls like fcntl(). Thus, it's indeed dangerous to define these.
Can't you build the new alsa-driver with old kernel? Then, together with the new alsa-lib, the problem should go away.
I can't build either alsa-driver 1.0.14 or 1.0.15rc1 - they bomb out with:
CC [M] /tmp/alsa-driver-1.0.15rc1/misc/ac97_bus.o In file included from /tmp/alsa-driver-1.0.15rc1/misc/ac97_bus.c:1: /tmp/alsa-driver-1.0.15rc1/misc/../alsa-kernel/ac97_bus.c:30: error: syntax error before "pm_message_t" /tmp/alsa-driver-1.0.15rc1/misc/../alsa-kernel/ac97_bus.c:31: warning: function declaration isn't a prototype /tmp/alsa-driver-1.0.15rc1/misc/../alsa-kernel/ac97_bus.c: In function `ac97_bus_suspend': /tmp/alsa-driver-1.0.15rc1/misc/../alsa-kernel/ac97_bus.c:34: error: `dev' undeclared (first use in this function) /tmp/alsa-driver-1.0.15rc1/misc/../alsa-kernel/ac97_bus.c:34: error: (Each undeclared identifier is reported only once /tmp/alsa-driver-1.0.15rc1/misc/../alsa-kernel/ac97_bus.c:34: error: for each function it appears in.) /tmp/alsa-driver-1.0.15rc1/misc/../alsa-kernel/ac97_bus.c:35: error: `state' undeclared (first use in this function) /tmp/alsa-driver-1.0.15rc1/misc/../alsa-kernel/ac97_bus.c: In function `ac97_bus_resume': /tmp/alsa-driver-1.0.15rc1/misc/../alsa-kernel/ac97_bus.c:45: error: too few arguments to function make[4]: *** [/tmp/alsa-driver-1.0.15rc1/misc/ac97_bus.o] Error 1
However, even if I could build 1.0.14/15rc1, I'm not sure if they would help - as I think the important output from the configure script (alsa-driver 1.0.13 and above) is:
checking for new unlocked/compat_ioctl... no
and in include/config.h:
/* #undef CONFIG_SND_HAVE_NEW_IOCTL */
So, as far as I can tell, means that I have to use the snd-ioctl32 module, which has the problems I originally described.
Is this correct?
Thanks
