add_margin_and_round_to_dfs_grainularity() When building with clang 19 or newer (which strengthened some of the enum conversion warnings for C), there is a warning (or error with CONFIG_WERROR=y) around doing arithmetic with an enumerated type and a floating point expression. drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_dpmm/dml2_dpmm_dcn4.c:181:58: error: arithmetic between enumeration type 'enum dentist_divider_range' and floating-point type 'double' [-Werror,-Wenum-float-conversion] 181 | divider = (unsigned int)(DFS_DIVIDER_RANGE_SCALE_FACTOR * (vco_freq_khz / clock_khz)); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. This conversion is expected due to the nature of the enumerated value and definition, so silence the warning by casting the enumeration to an integer explicitly to make it clear to the compiler.

2024-05-02drm/amd/display: Disable panel replay by default for nowMario Limonciello1-9/+12
Panel replay was enabled by default in commit 5950efe25ee0 ("drm/amd/display: Enable Panel Replay for static screen use case"), but it isn't working properly at least on some BOE and AUO panels. Instead of being static the screen is solid black when active. As it's a new feature that was just introduced that regressed VRR disable it for now so that problem can be properly root caused.

2024-05-02drm/panthor: Fix the FW reset logicBoris Brezillon1-3/+4
In the post_reset function, if the fast reset didn't succeed, we are not clearing the fast_reset flag, which prevents firmware sections from being reloaded. While at it, use panthor_fw_stop() instead of manually writing DISABLE to the MCU_CONTROL register.

2024-05-02drm/xe/gt: Fix assert in L3 bank mask generationFrancois Dugast1-1/+3
What needs to be asserted is that the pattern fits in the number of bits provided by the user in patternbits, otherwise it would be truncated when replicated according to the mask, which is likely not the intended use of this function. The pattern argument is a bitmap so use find_last_bit() instead of fls(). The bit position starts at index 0 so remove "or equal" from the comparison. XE_MAX_L3_BANK_MASK_BITS would be the returned value if the pattern is 0, which can be the case on some platforms. v2: Check the result does not overflow the array (Lucas De Marchi) v3: Use __fls() for long and handle mask == 0 (Lucas De Marchi) Cc: Matt Roper <[email protected]> Cc: Lucas De Marchi <[email protected]> Signed-off-by: Francois Dugast <[email protected]> Reviewed-by: Lucas De Marchi <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Lucas De Marchi <[email protected]>
2024-05-02drm/panthor: Make sure we handle 'unknown group state' case properlyBoris Brezillon1-2/+35
When we check for state values returned by the FW, we only cover part of the 0:7 range. Make sure we catch FW inconsistencies by adding a default to the switch statement, and flagging the group state as unknown in that case. When an unknown state is detected, we trigger a reset, and consider the group as unusable after that point, to prevent the potential corruption from creeping in other places if we continue executing stuff on this context. v2: - Add Steve's R-b - Fix commit message Reported-by: Dan Carpenter <[email protected]> Closes: https://lore.kernel.org/dri-devel/[email protected]/T/#u Suggested-by: Steven Price <[email protected]> Signed-off-by: Boris Brezillon <[email protected]> Reviewed-by: Steven Price <[email protected]> Reviewed-by: Liviu Dudau <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2024-05-02drm/xe/display: Fix ADL-N detectionLucas De Marchi1-1/+2
Contrary to i915, in xe ADL-N is kept as a different platform, not a subplatform of ADL-P. Since the display side doesn't need to differentiate between P and N, i.e. IS_ALDERLAKE_P_N() is never called, just fixup the compat header to check for both P and N. Moving ADL-N to be a subplatform would be more complex as the firmware loading in xe only handles platforms, not subplatforms, as going forward the direction is to check on IP version rather than platforms/subplatforms. Fix warning when initializing display: xe 0000:00:02.0: [drm:intel_pch_type [xe]] Found Alder Lake PCH ------------[ cut here ]------------ xe 0000:00:02.0: drm_WARN_ON(!((dev_priv)->info.platform == XE_ALDERLAKE_S) && !((dev_priv)->info.platform == XE_ALDERLAKE_P)) And wrong paths being taken on the display side.

2024-05-02drm: move DRM-related CONFIG options into DRM submenuMasahiro Yamada1-4/+8
When you create a submenu using the 'menu' syntax, there is no ambiguity about its end because the code between 'menu' and 'endmenu' becomes the submenu. In contrast, 'menuconfig' does not have the corresponding end marker. Instead, the end of the submenu is inferred from symbol dependencies. This is detailed in Documentation/kbuild/kconfig-language.rst, starting line 348. It outlines two methods to place the code under the submenu: (1) Open an if-block immediately after 'menuconfig', enclosing the submenu content within it (2) Add 'depends on' to every symbol intended for the submenu Many subsystems opt for (1) because it reliably maintains the submenu structure. The DRM subsystem adopts (2). The submenu ends when the sequence of 'depends on DRM' breaks. It can be confirmed by running a GUI frontend such as 'make menuconfig' and visiting the DRM menu: < > Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) ---- If you toggle this, you will notice most of the DRM-related options appear below it, not in the submenu. I highly recommend the approach (1). Obviously, (2) is not reliable, as the submenu breaks whenever someone forgets to add 'depends on DRM'. This commit encloses the entire DRM configuration with 'if DRM' and 'endif', except for DRM_PANEL_ORIENTATION_QUIRKS. Note: Now, 'depends on DRM' properties inside the if-block are all redundant. I leave it as follow-up cleanups.

2024-05-02drm/fbdev-dma: Implement damage handling and deferred I/OThomas Zimmermann1-14/+51
Add support for damage handling and deferred I/O to fbdev-dma. This enables fbdev-dma to support all DMA-memory-based DRM drivers, even such with a dirty callback in their framebuffers. The patch adds the code for deferred I/O and also sets a dedicated helper for struct fb_ops.fb_mmap that support coherent mappings. v3: - init fb_ops with FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS() (Javier) Signed-off-by: Thomas Zimmermann <[email protected]> Reviewed-by: Javier Martinez Canillas <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
