All the linux specific error_notifier codes are defined in linux specific header file <uapi/linux/nvgpu.h> and used in all the common driver But since they are defined in linux specific file, we need to move all the uses of those error_notifiers in linux specific code only Hence define new error_notifiers in include/nvgpu/error_notifier.h and use them in the common code Add new API nvgpu_error_notifier_to_channel_notifier() to convert common error_notifier of the form NVGPU_ERR_NOTIFIER_* to linux specific error notifier of the form NVGPU_CHANNEL_* Any future additions to error notifiers requires update to both the form of error notifiers Move all error notifier related metadata from channel_gk20a (common code) to linux specific structure nvgpu_channel_linux Update all accesses to this data from new structure instead of channel_gk20a Move and rename below APIs to linux specific file and declare them in error_notifier.h nvgpu_set_error_notifier_locked() nvgpu_set_error_notifier() nvgpu_is_error_notifier_set() Add below new API and use it in fifo_vgpu.c nvgpu_set_error_notifier_if_empty() Include <nvgpu/error_notifier.h> wherever new error_notifier codes are used NVGPU-426 Change-Id: Iaa5bfc150e6e9ec17d797d445c2d6407afe9f4bd Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1593361 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
