When we iterate over ti_sn_bridge_dp_rate_lut, there's no reason to start at index 0 which always contains the value 0. 0 is not a valid link rate. This change should have no real effect but is a small cleanup. Signed-off-by:

These two things were in one function. Split into two. This looks like it's duplicating some code, but don't worry. This is is just in preparation for future changes. This is intended to have zero functional change and will just make future patches easier to understand. Signed-off-by:

This patch reworks the whole delayed deletion of BOs which aren't idle. Instead of having two counters for the BO structure we resurrect the BO when we find that a deleted BO is not idle yet. This has many advantages, especially that we don't need to increment/decrement the BOs reference counter any more when it moves on the LRUs. v2: remove duplicate ttm_tt_destroy, fix holde lock for LRU move Signed-off-by:

There is no real reason to require drivers to set and use dev->dev_private. Indeed, the current recommendation, as documented in drm_device.h, is to embed struct drm_device in the per-device struct instead of using dev_private. Remove the requirement for dev_private to have been set to indicate driver initialization. For background, quoting Daniel Vetter: Now there might be some hilarious races this papers over, but: - Proper drivers should only call drm_dev_register once everything is set up, including this stuff here. No race possible with anything else really. - Slightly more wobbly drivers, including the legacy ones, all use drm_global_mutex. This was the former BKL, which means that it was impossible for soeone to go through the load/unload/reload (between lastclose and firstopen) paths and also run the ioctl. But the ioctl had to be made unlocked because blocking there killed X: commit 8f4ff2b0 Author: Ilija Hadzic <ihadzic@research.bell-labs.com> Date: Mon Oct 31 17:46:18 2011 -0400 drm: do not sleep on vblank while holding a mutex The even more legacy DRM_CONTROL ioctl stayed fully locked. But the file open/close paths are still fully locked, and that's the only place legacy drivers should call drm_irq_install/uninstall, so should all still be fully ordered and protected and happy.

This catches the majority of drivers (unfortunately not if we take users into account, because all the big drivers have at least a lastclose hook). With the prep patches out of the way all drm state is fully protected and either prevents or can deal with the races from dropping the BKL around open/close. The only thing left to audit are the various driver hooks - by keeping the BKL around if any of them are set we have a very simple cop-out! Note that one of the biggest prep pieces to get here was making dev->open_count atomic, which was done in commit 7e13ad89 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Jan 24 13:01:07 2020 +0000 drm: Avoid drm_global_mutex for simple inc/dec of dev->open_count v2: - Rebase and fix locking in drm_open() (Chris) - Indentation fix in drm_release - Typo fix in the commit message (Sam) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Sam Ravnborg <sam@ravnborg.org> Reviewed-by:

We want to only take the BKL on crap drivers, but to know whether we have a crap driver we first need to look it up. Split this shuffle out from the main BKL-disabling patch, for more clarity. Historical aside: When the kernel-wide BKL was removed, it was replaced by drm_global_mutex within the scope of the drm subsystem hence why these two things are (almost) interchangeable as concepts here. Since the minors are refcounted drm_minor_acquire is purely internal and this does not have a driver visible effect. v2: Push the locking even further into drm_open(), suggested by Chris. This gives us more symmetry with drm_release(), and maybe a futuer avenue where we make drm_global_mutex locking (partially) opt-in like with drm_release_noglobal(). v3: - Actually push this stuff correctly, don't unlock twice (Chris) - Fix typo on commit message, plus explain why BKL = drm_global_mutex (Sam) Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Chris Wilson <chris@chris-wilson.co.uk> Tested-by:

Plus extend the kerneldoc a bit to explain how this should be used. With the previous patch to drop the force restore the main user of this function is not emphasis on the "I hold the internal master lock already" aspect, so rename the function to match.

Instead check for master status, in case we've raced. This is the last exception to the general rule that we restore fbcon only when there's no master active. Compositors are supposed to drop their master status before they switch to a different console back to text mode (or just switch to text mode directly, without a vt switch). This is known to break some subtests of kms_fbcon_fbt in igt, but they're just wrong - it does a graphics/text mode switch for the vt without updating the master status. Also add a comment to the drm_client->restore hook that this is expected going forward from all clients (there's currently just one). v2: Also drop the force in pan_display v3: Restore the _force to pan_display, this actually means _locked in that path.
