Skip the transcoder whose pipe is disabled while initializing transcoder error state in 3 non-contiguous display pipe system. v2: - Don't skip EDP_TRANSCODER error state. [Ville] - Use a helper has_transcoder(). [Ville] v3: - Removed DSI transcoder case from has_transcoder(), and few other cosmetic changes.

we can't have (pipe == crtc->index) assumption in driver in order to support 3 non-contiguous display pipe system. FIXME: Remove the WARN_ON(drm_crtc_index(&crtc->base) != crtc->pipe) when we will fix all such assumption. changes since RFC: - Added again removed (pipe == crtc->index) WARN_ON. - Pass drm_crtc_index instead of intel pipe in order to call drm_handle_vblank(). v2: - Used drm_crtc_handle_vblank()/drm_crtc_wait_one_vblank() instead of drm_handle_vblank/drm_wait_one_vblank(). [Jani] - Introduced intel_handle_vblank() helper to avoid sprinkle of intel_crtc across irq_handlers. [Ville] v3: - Moved intel_handle_vblank() from header to i915_irq.c.

It should not be assumed that a disabled display pipe will be always last the pipe. for_each_pipe() should iterate over I915_MAX_PIPES and check for the disabled pipe and skip that pipe so that it should not initialize the intel crtc for any disabled pipes. Due to changes in for_each_pipe() macro, it requires to handle the below compilation error. "suggest explicit braces to avoid ambiguous ‘else’ [-Werror=dangling-else]" v2: - Cosmetic changes, removed unwanted parentheses.

Commit 60c6a14b ("drm/i915/display: Force the state compute phase once to enable PSR") was forcing the state compute too earlier causing errors because not everything was initialized, so here moving to the end of i915_driver_modeset_probe() when the display is all initialized. Also fixing the place where it disarm the force probe as during the atomic check phase errors could happen like the ones due locking and it would cause PSR to never be enabled if that happens. Leaving the disarm to the atomic commit phase, intel_psr_enable() or intel_psr_update() will be called even if the current state do not allow PSR to be enabled. v2: Check if intel_dp is null in intel_psr_force_mode_changed_set() v3: Check intel_dp before get dev_priv v4: - renamed intel_psr_force_mode_changed_set() to intel_psr_set_force_mode_changed() - removed the set parameter from intel_psr_set_force_mode_changed() - not calling intel_psr_set_force_mode_changed() from intel_psr_enable/update(), directly setting it after the same checks that intel_psr_set_force_mode_changed() does - moved intel_psr_set_force_mode_changed() arm call to i915_driver_modeset_probe() as it is a better for a PSR call, all the functions calls happening between the old and the new function call will cause issue Fixes: 60c6a14b ("drm/i915/display: Force the state compute phase once to enable PSR") Closes: https://gitlab.freedesktop.org/drm/intel/issues/1151Tested-by:

Variables declared in a switch statement before any case statements cannot be automatically initialized with compiler instrumentation (as they are not part of any execution flow). With GCC's proposed automatic stack variable initialization feature, this triggers a warning (and they don't get initialized). Clang's automatic stack variable initialization (via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also doesn't initialize such variables[1]. Note that these warnings (or silent skipping) happen before the dead-store elimination optimization phase, so even when the automatic initializations are later elided in favor of direct initializations, the warnings remain. To avoid these problems, move such variables into the "case" where they're used or lift them up into the main function body. drivers/gpu/drm/i915/display/intel_display.c: In function ‘check_digital_port_conflicts’: drivers/gpu/drm/i915/display/intel_display.c:12963:17: warning: statement will never be executed [-Wswitch-unreachable] 12963 | unsigned int port_mask; | ^~~~~~~~~ drivers/gpu/drm/i915/intel_pm.c: In function ‘vlv_get_fifo_size’: drivers/gpu/drm/i915/intel_pm.c:474:7: warning: statement will never be executed [-Wswitch-unreachable] 474 | u32 dsparb, dsparb2, dsparb3; | ^~~~~~ drivers/gpu/drm/i915/intel_pm.c: In function ‘vlv_atomic_update_fifo’: drivers/gpu/drm/i915/intel_pm.c:1997:7: warning: statement will never be executed [-Wswitch-unreachable] 1997 | u32 dsparb, dsparb2, dsparb3; | ^~~~~~ [1] https://bugs.llvm.org/show_bug.cgi?id=44916Reviewed-by:Kees Cook <keescook@chromium.org> Signed-off-by:

Manual conversion of instances of printk based drm logging macros to the struct drm_device based logging macros in i915/i915_perf.c. Also involves extraction of the struct drm_i915_private device from various intel types for use in the macros. Instances of the DRM_DEBUG printk macro were not converted due to the lack of an analogous struct drm_device based logging macro. v2: remove instances of DRM_DEBUG that were converted.

On gen11 we only needed to program MBus credits into MBUS_ABOX_CTL during display initialization, but on gen12 we're now supposed to program the same values into MBUS_ABOX1_CTL and MBUS_ABOX2_CTL as well. v2: - Program registers with rmw to preserve contents of unrelated bits. - Switch to the new display uncore helpers.

It wasn't terribly clear from the bspec's wording, but after discussion with the hardware folks, it turns out that we need to preserve the pre-existing contents of the MBUS ABOX control register when initializing a few specific bits.

We have to write quite a few registers when programming the pipe scaler. Let's use intel_de_write_fw() for these to reduce the lockdep overhead a bit. All plane registers (including plane scaler) already do this. We already had a few accidental intel_de_write_fw() in there. Signed-off-by:
