Hook up steamcompmgr output pipeline. Get steamcompmgr's GL context from EGL and rip out GLX, as we need EGL to import dma-bufs. When new buffers are committed to surfaces, push their information to steamcompmgr (without any feedback for now, fire-and-forget). Can render games now. 2019-10-27 03:57:54 +00:00

steamcompmgr: also set thread priorities for ourselves and Xwayland. Avoid setting it for our children processes, by spawning them in a new thread group and setting group-wide priority, which also conveniently gets Xwayland. 2020-09-02 07:27:18 +00:00			`extern bool g_bNiceCap;`
Different method of bumping priority. Calling nice() in the very beginning ensures that Mesa worker threads in gamescope and Xwayland can properly reduce their priority without us stomping it later. Move away from posix_spawn, since there's no easy way (that seems to work) to keep priority normal for the spawned process and get the right behaviour for gamescope and Xwayland. The intermediate fork() lets us simplify the logic for LD_PRELOAD rewriting. 2020-09-02 18:02:31 +00:00			`extern int g_nOldNice;`

Add realtime flag for SCHED_RR Use sched_get_priority_min for priority Accommodates other unixes with odd minimum priorities. Manually handle save/restore of scheduling. Add space. (formatting) Exit on failure to get scheduler parameters. Add missing braces. Copy and edit existing sched_parm rather than new.

main: Raise the file descriptor limit at launch Gamescope currently uses 1024 VkFence objects to synchronize CPU and GPU work. The NVIDIA Vulkan driver currently creates a file descriptor for each VKFence object created. To ensure there are sufficient file descriptors, attempt to raise the limit to 2048 file descriptors if it is currently lower than that. Failure to raise the limit for any reason is non-fatal, as the increased limit is not required on some drivers. 2022-03-14 16:59:02 +00:00			`void restore_fd_limit( void );`
