[alsa-devel] alsa git: which version of ac97_codec.c am i supposed to hxr?
Hello All;
I feel confused by the presence of 2 different copies of ac97_codec.c:
jutz-gnto ~ # find . -name ac97_codec.c ./alsa-driver/pci/ac97/ac97_codec.c ./alsa-kmirror/pci/ac97/ac97_codec.c
worse yet,they are not in sync:
jutz-gnto ~ # diff -w ./alsa-driver/pci/ac97/ac97_codec.c ./alsa-kmirror/pci/ac97/ac97_codec.c 1d0 < #include "adriver.h" 38c37 < #include "../../alsa-kernel/pci/ac97/ac97_id.h" ---
#include "ac97_id.h"
40c39 < #include "../../alsa-kernel/pci/ac97/ac97_patch.c" ---
#include "ac97_patch.c"
1917d1915 < #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 0) 1929d1926 < #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 14) 1931d1927 < #endif 1953,1956d1948 < #else /* <= 2.6.0 */ < #define snd_ac97_dev_register NULL < #define snd_ac97_dev_disconnect NULL < #endif
Which of these am i supposed to use? am i supposed to change both of them for some backward compatibility purpose?
tnx!

Modify the alsa-kmirror code. When you run make in alsa-driver tree, the file from alsa-kmirror is patched to retain compatibility for older linux kernels. The ac97_codec.c file in alsa-driver tree is just a temporary file (not in our repository) used for building. See to .gitignore which files are temporary only.
