nouveau_usif.c was already stripped right back a couple of years ago, limiting what userspace could do with it. A follow-on series removes the nvkm side of these interfaces entirely, in order to make it less of a nightmare to add/change internal APIs in the future. Unfortunately. Userspace uses some of this. Fortunately, userspace only ever ended up using a fraction of the APIs, so those are reimplemened here in a more direct manner, and return -EINVAL to userspace for everything else. v2: - simplified struct nouveau_abi16_obj - added a couple of comments v3: - comment harder Signed-off-by:

Ben Skeggs authored
drm->master isn't really a nouveau_cli, and is mostly just used to get at an nvif_mmu object to implement a hack around issues with the ioctl interface to nvkm. Later patches in this series allocate nvif_device/mmu objects in nouveau_drm directly, removing the need for master. A pending series to remove the "ioctl" layer between DRM and NVKM removes the need for the above-mentioned hack entirely. The only other member of drm->master that's needed is the nvif_client, and is a dependency of device/mmu. So the first step is to move its allocation out of code handling nouveau_cli init. v2: - modified slightly due to the addition of tegra/pci cleanup patches v3: - move nvif init below drm_dev_alloc() to avoid changing nouveau_name() Signed-off-by:

There's various different places in the drm code that get at the nvkm_device via various creative (and not very type-safe) means. One of those being via nvif_device.object.priv. Another patch series is going to entirely remove the ioctl-like interfaces beween the drm code and nvkm, and that field will no longer exist. This provides a safer replacement for accessing the nvkm_device, and will used more in upcoming patches to cleanup other cases. v2: - fixup printk macros to not oops if used before client ctor Signed-off-by:

HW isn't touched anymore (aside from detection) until the first nvif_device has been allocated, so we no longer need a separate probe-only step before kicking efifb (etc) off the HW. Signed-off-by:

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:

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:
