Drive-by fixup while looking at all the connector_list walkers - holding connection_mutex does actually _not_ give you locking to look at the legacy drm_connector->encoder->crtc pointer chain. That one is solely owned by the atomic commit workers. Instead we must inspect the atomic state.

While at it also try to reduce the locking a bit to what's really just needed instead of everything that we could possibly lock. Added a new for_each_intel_connector_iter which includes the cast to intel_connector. Otherwise just plain transformation with nothing special going on. v2: Review from Maarten: - Stick with modeset_lock_all in sink_crc, it looks at crtc->state. - Fix up early loop exit in i915_displayport_test_active_write. v3: Rebase onto the iter_get/put->iter_begin/end rename.

printks are slow so we should not be doing them from the vblank evade critical section. These could explain why we sometimes seem to blow past our 100 usec deadline. The problem has been there ever since commit bfd16b2a ("drm/i915: Make updating pipe without modeset atomic.") but it may not have been readily visible until commit e1edbd44 ("drm/i915: Complain if we take too long under vblank evasion.") increased our chances of noticing it.

Backmerge drm-next to get at all the good stuff in drm-misc. We need that because: - drm_connector_list_iter conversion for i915 needs the core patches. - Maarten's patches to use the new atomic state iterators also need the core patches. - We need the new link status property to complete the DP retraining work, merging through 2 branches wasn't a good idea and we had to partially backtrack. - Chris needs reservation_object_trylock and we want to roll out kref_read everywhere.

Before we instantiate/pin the backing store for our use, we can prepopulate the shmemfs filp efficiently using a write into the pagecache. We avoid the penalty of instantiating all the pages, important if the user is just writing to a few and never uses the object on the GPU, and using a direct write into shmemfs allows it to avoid the cost of retrieving a page (mostly the clear-before-use, but in theory we could curtail swapin) before it is overwritten. This can be extended later to provide additional specialisation for other backends (other than shmemfs). For now it provides a defense against very large write-only allocations from exhausting all of system memory. v2: Smelling fixes.

The IS_G4X macro is defined as IS_G45 || IS_GM45. We have two points in our code where we have an if statement checking for GM45 followed by an else if statement checking for IS_G4X. This can be confusing since the IS_G4X check won't be catching the previously-checked GM45. Someone quickly trying to check which functions run on each platform may end up getting confused while reading the code. Fix the potential confusion by limiting the else if statements to only check for the platform that was not already checked earlier in the if ladder.

The hook names reflect more the phase in the mode set sequence the hooks are called in than what they actually do in terms of the specific encoder. Stick to that scheme, and rename intel_dsi_pre_disable to intel_dsi_disable. Unify the comments around this while at it.

Commit 18a00095 ("drm/i915/dsi: Make intel_dsi_enable/disable directly exec VBT sequences") started calling the VBT sequence functions directly instead of using the drm_panel hooks. Remove the last drm_panel hook by calling vbt_panel_get_modes() directly. No functional changes.

This commit reworks the RAM detection algorithm, using RAM-per-LTC to determine whether a board has a mixed-memory configuration instead of using RAM-per-FBPA. I'm not certain the algorithm is perfect, but it should handle all currently known configurations in the very least. This should fix GTX 970 boards with 4GiB of RAM where the last 512MiB isn't fully accessible, as well as only detecting half the VRAM on GF108 boards. As a nice side-effect, GP10x memory detection now reuses the majority of the code from earlier chipsets. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
