We almost always want to cast the pointer from dev_get_drvdata() to 'struct nouveau_drm *', so just directly store that pointer instead, simplifying callers, and fixing some clumsy naming of dev/drm_dev variables at the same time. Signed-off-by:

Unify some more of the PCI/Tegra DRM driver init, both as a general cleanup, and because a subsequent commit changes the pointer stored via dev_set_drvdata(), and this allows the change to be made in one place. Signed-off-by:

The next commit wants to be able to call fini() from an init() failure path to remove the need to duplicate a bunch of cleanup. Moving fini() above init() avoids the need for a forward-declaration. Signed-off-by:

We would like to be able to enable vblank_disable_immediate unconditionally, however there are a handful of cases where a small off delay is necessary (e.g. with PSR enabled). So, we would like to be able to adjust the vblank off delay and disable imminent values dynamically for a given CRTC. Since, it will allow drivers to apply static screen optimizations more quickly and consequently allow users to benefit more so from the power savings afforded by the aforementioned optimizations, while avoiding issues in cases where an off delay is still warranted. In particular, the PSR case requires a small off delay of 2 frames, otherwise display firmware isn't able to keep up with all of the requests made to amdgpu. So, introduce drm_crtc_vblank_on_config() which is like drm_crtc_vblank_on(), but it allows drivers to specify the vblank CRTC configuration before enabling vblanking support for a given CRTC.

Before building an image, the build script looks to see if there are fixes to apply from an upstream repository. The link for the upstream repository git://anongit.freedesktop.org/drm/drm became obsolete with the move to Gitlab server in March 2024. Until recently, this obsolete link was harmless because anongit would at least respond that there were no such fixes available. In the last few days anongit has stopped responding to requests causing the build script to hang indefinitely. Update the link from anongit to the Gitlab server to prevent the build script from hanging indefinitely. Signed-off-by:

The preemphasis can be set separately for both DP lanes in range 0=0dB, 1=3.5dB, 2=6dB . This is an endpoint property, not a port property, because the TC9595 datasheet does mention that the DP might operate in some sort of split mode, where each DP lane is used to feed one display, so in that case there might be two endpoints.

Limiting the allocation of higher order pages to the closest NUMA node and enabling direct memory reclaim provides not only failsafe against situations when memory becomes too much fragmented and the allocator is not able to satisfy the request from the local node but falls back to remote pages (HUGEPAGE) but also offers performance improvement. Accessing remote pages suffers due to bandwidth limitations and could be avoided if memory becomes defragmented and in most cases without using manual compaction. (/proc/sys/vm/compact_memory) Note: On certain distros such as RHEL, the proactive compaction is disabled.

At shutdown if you've got a _properly_ coded DRM modeset driver then you'll get these two warnings at shutdown time: Skipping disable of already disabled panel Skipping unprepare of already unprepared panel These warnings are ugly and sound concerning, but they're actually a sign of a properly working system. That's not great. We're not ready to get rid of the calls to drm_panel_disable() and drm_panel_unprepare() because we're not 100% convinced that all DRM modeset drivers are properly calling drm_atomic_helper_shutdown() or drm_helper_force_disable_all() at the right times. However, having the warning show up for correctly working systems is bad. As a bit of a workaround, add some "if" tests to try to avoid the warning on correctly working systems. Also add some comments and update the TODO items in the hopes that future developers won't be too confused by what's going on here. Suggested-by:
