2025-05-22drm/i915/display: Add check for alloc_ordered_workqueue() and alloc_workqueue()Haoxiang Li
Add check for the return value of alloc_ordered_workqueue() and alloc_workqueue(). Furthermore, if some allocations fail, cleanup works are added to avoid potential memory leak problem.

2025-04-25drm/i915/vga: Consolidate intel_vga_disable() callsVille Syrjälä
Currently we disable the VGA plane from various places, sometimes multiple times in the same init/resume sequence. Get rid of all this mess and do it just once. The most correct place seems to be just after intel_early_display_was() as that one applies various workarounds that need to be in place before we touch any planes (including the VGA plane). Actually, we do still have a second caller in vlv_display_power_well_init(). I think we still need that as the reset value of VGACNTR is 0x0 and thus technically the VGA plane will be (at least partially) enabled after the power well has been toggled. In both cases we have the necessary power reference already held (INIT power domain for load/resume case, and the display power well itself being what we need for vlv_display_power_well_init()).

2025-04-23drm/i915/psr: Apply underrun on PSR idle workaroundJouni Högander
This patch is applying workaround for underrun on idle PSR HW issue (Wa_16025596647) when PSR is getting enabled. It uses vblank enable/disable status, DC5/6 enabled disabled and enabled pipes count information made available. This patch is also adding calls to dc5/dc6, vblank enable/disable and pipe enable/disable notification functions as needed. intel_psr_needs_block_dc_vblank is modified to get vblank enable/disable notification on PSR capable system. v2: use intel_dmc interface instead of directly writing dmc register Bspec: 74151 Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Mika Kahola <mika.kahola@intel.com> Link: https://lore.kernel.org/r/20250414100508.1208774-12-jouni.hogander@intel.com

2024-12-02drm/i915/display: convert high level power interfaces to struct intel_displayJani Nikula
Going forward, struct intel_display is the main device data structure for display. Convert the high level interfaces (init, cleanup, suspend, resume, etc.) of intel_display_power.c over to it. The actual power get/put etc. are left for follow-up.

2024-11-28drm/i915/dpt: Evict all DPT VMAs on suspendVille Syrjälä
Currently intel_dpt_resume() tries to blindly rewrite all the PTEs for currently bound DPT VMAs. That is problematic because the CPU mapping for the DPT is only really guaranteed to exist while the DPT object has been pinned. In the past we worked around this issue by making DPT objects unshrinkable, but that is undesirable as it'll waste physical RAM. Let's instead forcefully evict all the DPT VMAs on suspend, thus guaranteeing that intel_dpt_resume() has nothing to do. To guarantee that all the DPT VMAs are evictable by intel_dpt_suspend() we need to flush the cleanup workqueue after the display output has been shut down. And for good measure throw in a few extra WARNs to catch any mistakes.
