Let's do a frontbuffer flush on dirty fb. To be used for DIRTYFB drm ioctl. This patch solves the biggest PSR known issue, that is missed screen updates during boot, mainly when there is a splash screen involved like Plymouth. Previously PSR was being invalidated by fbdev and Plymounth was taking control with PSR yet invalidated and could get screen updates normally. However with some atomic modeset changes Pymouth modeset over ioctl was now causing frontbuffer flushes making PSR gets back to work while it cannot track the screen updates and exit properly. By adding this flush on dirtyfb we properly track frontbuffer writes and properly exit PSR. Actually all mmap_wc users should call this dirty callback in order to have a proper frontbuffer tracking. In the future it can be extended to return 0 if the whole screen has being flushed or the number of rects flushed as Chris suggested. v2: Remove ORIGIN_FB_DIRTY and use ORIGIN_GTT instead since dirty callback is just called after few screen updates and not on everyone as pointed by Daniel. v3: Use flush instead of invalidate since flush means invalidate + flush and dirty means drawn had finished and it can be flushed. v4: Remove PSR from subject since it is purely frontbuffer tracking change and that can be useful for FBC as well.

Since flush actually means invalidate + flush we need to force psr exit on PSR flush. On Core platforms there is no way to disable hw tracking and do the pure sw tracking so we simulate it by fully disable psr and reschedule a enable back. So a good idea is to minimize sequential disable/enable in cases we know that HW tracking like when flush has been originated by a flip. Also flip had just invalidated it already. It also uses origin to minimize the a bit the amount of disable/enabled, mainly when flip already had invalidated. With this patch in place it is possible to do a flush on dirty areas properly in a following patch. v2: Remove duplicated exit on HSW+Sprites as pointed out by Paulo.

wa_ctx_emit() depends on the name of a local variable; if the name of that variable is changed then we get compile errors. In this case it is unlikely to be changed as this macro is only used in this set of functions but Kernel coding guidelines doesn't recommend doing this. It was my mistake as I should have corrected it at the beginning but missed so correct this before there are more usages of this macro (Bob Beckett). https://www.kernel.org/doc/Documentation/CodingStyle, Chapter 12, "Things to avoid when using macros", point 2): " 2) macros that depend on having a local variable with a magic name: #define FOO(val) bar(index, val) might look like a good thing, but it's confusing as hell when one reads the code and it's prone to breakage from seemingly innocent changes. " v2: Optimization to avoid multiple evaluation of 'index' in the macro. Since we invoke it multiple times, compiler, if it can, should be able to coalesce them into a single condition and remove multiple WARN_ON checks (Chris). Suggested-by:

I have two separate refactor ideas that require extracting this to a separate function. I'm not sure which idea I'll end choosing, but since both will require extracting this function, let's do this now. Notice that this is just code moving. Any possible problems with the current multiple pipes check should be fixed in later commits. Signed-off-by:

Because the cool kids use dev_priv and FBC wants to be cool too. We've been historically using struct drm_device on the FBC function arguments, but we only really need it for intel_vgpu_active(): we can use dev_priv everywhere else. So let's fully switch to dev_priv since I'm getting tired of adding "struct drm_device *dev = dev_priv->dev" everywhere. If I get a NACK here I'll propose the opposite: convert all the functions that currently take dev_priv to take dev. Signed-off-by:

intel_atomic_setup_scalers() dereferences 'plane' before the plane has been assigned. The plane ID assignment doing this dereference is only needed for debugging messages later in the function, so just move the assignment farther down the function to a point where plane will no longer be NULL.

It is found that i915 will not reset gpu under execlist mode when unload module. that will lead to some issues when unload/load module with different submission mode. e.g. from execlist mode to ring buffer mode via loading/unloading i915. Because HW is not in a reset state and registers are not clean under such condition. Signed-off-by:

In this WA we need to set GEN8_L3SQCREG4[21:21] and reset it after PIPE_CONTROL instruction but there is a slight complication as this is applied in WA batch where the values are only initialized once. Dave identified an issue with the current implementation where the register value is read once at the beginning and it is reused; this patch corrects this by saving the register value to memory, update register with the bit of our interest and restore it back with original value. This implementation uses MI_LOAD_REGISTER_MEM which is currently only used by command parser and was using a default length of 0. This is now updated with correct length and moved to appropriate place. Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Dave Gordon <david.s.gordon@intel.com> Signed-off-by:

Make sure we're not going to have weird races in really weird cases where a lot of different CRTCs are doing rendering and modesets at the same time.

Which should protect dev_priv->mm.stolen usage. This will allow us to simplify the relationship between stolen memory, FBC and struct_mutex. v2: - Rebase after the stolen_remove_node() dev_priv patch move. - I realized that after we fixed a few things related to the FBC CFB size checks, we're not reallocating the CFB anymore with FBC enabled, so we can just move all the locking to i915_gem_stolen.c and stop worrying about freezing all the stolen alocations while freeing/rellocating the CFB. This allows us to fix the "Too coarse" observation from Chris. Suggested-by: -

With the abstractions created by the last patch, we can move this code and the only thing inside intel_fbc.c that knows about dev_priv->mm is the code that reads stolen_base. We also had to move a call to i915_gem_stolen_cleanup_compression() - now called intel_fbc_cleanup_cfb() - outside i915_gem_stolen.c. v2: - Rebase after the remove_node() changes on the previous patch.

Paulo Zanoni authored
We want to move the FBC code out of i915_gem_stolen.c, but that code directly adds/removes stolen memory nodes. Let's create this abstraction, so i915_gme_stolen.c is still in control of all the stolen memory handling. The abstraction will also allow us to add locking assertions later. v2: - Add dev_priv as remove_node() argument since we'll need it later (Chris). Requested-by: -
