Merge tag 'exynos-drm-next-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next New feature - Add BGR pixel format support for FIMD device. As for this, this patch uses undocumented register, WIN_RGB_ORDER, but it is safe because product kernels have been using same register. Signed-off-by:

In the downstream kernels for exynos4 and exynos5 devices, there is an undocumented register that controls the order of the RGB output. It can be set to either normal order or reversed, which enables BGR support for those SoCs. This patch enables the BGR support for all the SoCs that were found to have at least one device with this logic in the corresponding downstream kernels. Signed-off-by:

TE-gpio, if defined, is placed in the panel's node, not the parent DSI node. Change the devm_gpiod_get_optional() to gpiod_get_optional() and pass proper device node to it. The code already has a proper cleanup path, so it looks that the devm_* variant has been applied accidentally during the conversion to gpiod API.

TE-gpio is optional and if it is not found then gpiod_get_optional() returns NULL. In such case the code will continue and try to convert NULL gpiod to irq what in turn fails. The failure is then propagated and driver is not registered. Fix this by returning early from exynos_dsi_register_te_irq() if no TE-gpio is found.

The rcar-du driver goes to great lengths to preserve device tree backward compatibility for the LVDS encoders by patching old device trees at runtime. The last R-Car Gen2 platform was converted to the new bindings commit edb0c3af ("ARM: dts: r8a7793: Convert to new LVDS DT bindings"), in v4.17, and the last RZ/G1 platform converted in commit 6a6a7976 ("ARM: dts: r8a7743: Convert to new LVDS DT bindings"), in v5.0. Both are older than commit 58256143 ("clk: renesas: Remove R-Car Gen2 legacy DT clock support"), in v5.5, which removes support for legacy bindings for clocks. The LVDS compatibility code is thus not needed anymore. Drop it. Signed-off-by:

Registers that exist in the shared render/compute reset domain need to be placed on an engine workaround list to ensure that they are properly re-applied whenever an RCS or CCS engine is reset. We have a number of workarounds (updating registers MLTICTXCTL, L3SQCREG1_CCS0, GEN12_MERT_MOD_CTRL, and GEN12_GAMCNTRL_CTRL) that are incorrectly implemented on the 'gt' workaround list and need to be moved accordingly.

Additional workarounds are required once we start exposing CCS engines. Note that we have a number of workarounds that update registers in the shared render/compute reset domain. Historically we've just added such registers to the RCS engine's workaround list. But going forward we should be more careful to place such workarounds on a wa_list for an engine that definitely exists and is not fused off (e.g., a platform with no RCS would never apply the RCS wa_list). We'll keep rcs_engine_wa_init() focused on RCS-specific workarounds that only need to be applied if the RCS engine is present. A separate general_render_compute_wa_init() function will be used to define workarounds that touch registers in the shared render/compute reset domain and that we need to apply regardless of what render and/or compute engines actually exist. Any workarounds defined in this new function will internally be added to the first present RCS or CCS engine's workaround list to ensure they get applied (and only get applied once rather than being needlessly re-applied several times).

HW resources are divided across the active CCS engines at the compute slice level, with each CCS having priority on one of the cslices. If a compute slice has no enabled DSS, its paired compute engine is not usable in full parallel execution because the other ones already fully saturate the HW, so consider it fused off. v2 (José): - moved it to its own function - fixed definition of ccs_mask v3 (Matt): - Replace fls() condition with a simple IP version test v4 (Matt): - Don't try to calculate a ccs_mask using intel_slicemask_from_dssmask() until we've determined that we're running on an Xe_HP platform where the logic makes sense (and won't overflow).

The compute engine handles the same commands the render engine can (except 3D pipeline), so it makes sense that CCS is more similar to RCS than non-render engines. The CCS context state (lrc) is also similar to the render one, so reuse it. Note that the compute engine has its own CTX_R_PWR_CLK_STATE register. In order to avoid having multiple RCS && CCS checks, add the following engine flag: - I915_ENGINE_HAS_RCS_REG_STATE - use the render (larger) reg state ctx.

The reset domain is shared between render and all compute engines, so resetting one will affect the others. Note: Before performing a reset on an RCS or CCS engine, the GuC will attempt to preempt-to-idle the other non-hung RCS/CCS engines to avoid impacting other clients (since some shared modules will be reset). If other engines are executing non-preemptable workloads, the impact is unavoidable and some work may be lost.
