From 045823a98c30fbcafa6d6b61a28b284de7038f07 Mon Sep 17 00:00:00 2001 From: Filip Bozuta Date: Wed, 15 Jan 2020 20:36:46 +0100 Subject: [PATCH] linux-user: Add support for selected alsa timer instructions using ioctls This patch implements functionalities of following ioctls: SNDRV_TIMER_IOCTL_START - Start selected alsa timer Starts the timer device that is selected. The third ioctl's argument is ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be called first to select the timer that is to be started. If no timer is selected, the error EBADFD ("File descriptor in bad shape") is returned. SNDRV_TIMER_IOCTL_STOP - Stop selected alsa timer Stops the timer device that is selected. The third ioctl's argument is ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be called first to select the timer that is to be stopped. If no timer is selected, the error EBADFD ("File descriptor in bad shape") is returned. SNDRV_TIMER_IOCTL_CONTINUE - Continue selected alsa timer Continues the timer device that is selected. The third ioctl's argument is ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be called first to select the timer that is to be continued. If no timer is selected, the error EBADFD ("File descriptor in bad shape") is returned. SNDRV_TIMER_IOCTL_PAUSE - Pause selected alsa timer Pauses the timer device that is selected. The third ioctl's argument is ignored. Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be called first to select the timer that is to be paused. If no timer is selected, the error EBADFD ("File descriptor in bad shape") is returned. Implementation notes: Since all of the implemented ioctls have NULL as their third argument, their implementation was straightforward.
