2026-04-28drm/amd/display: Update MCIF_ADDR macro to address IGT DWB regressionGaghik Khachatrian
[Why] A previous warning-fix commit updated type casts in the DCN3 mmhubbub code but missed updating the MCIF_ADDR macro to the correct, fully parenthesized and casted version. This caused a regression during DWB tests, where address values could be misinterpreted, potentially leading to incorrect hardware programming. [How] Updated the MCIF_ADDR macro in dcn30_mmhubbub.c to use the proper parenthesization and type casting, ensuring correct address handling. Removed redundant casts from REG_UPDATE calls for improved clarity and consistency with current coding standards.

2026-04-27drm/gem: Fix inconsistent plane dimension calculation in ↵Ashutosh Desai
drm_gem_fb_init_with_funcs() drm_gem_fb_init_with_funcs() computes sub-sampled plane dimensions using plain integer division: unsigned int width = mode_cmd->width / (i ? info->hsub : 1); unsigned int height = mode_cmd->height / (i ? info->vsub : 1); However, the ioctl-level framebuffer_check() in drm_framebuffer.c uses drm_format_info_plane_width/height() which round up dimensions via DIV_ROUND_UP(). This inconsistency corrupts the subsequent GEM object size check for certain pixel format and dimension combinations. For example, with NV12 (vsub=2) and a 1-pixel-tall framebuffer the GEM size validation path sees height=0 instead of height=1. The expression (height - 1) then wraps to UINT_MAX as an unsigned int, causing min_size to overflow and wrap back to a small value. A tiny GEM object therefore passes the size guard, yet when the GPU accesses the chroma plane it will read or write memory beyond the object's bounds. Fix by replacing the open-coded divisions with drm_format_info_plane_width() and drm_format_info_plane_height(), which use DIV_ROUND_UP() and match the calculation already used in framebuffer_check().

2026-04-24drm/amdgpu/gfx6: Support harvested SI chips with disabled TCCs (v2)Timur Kristóf
This commit fixes amdgpu to work on the Radeon HD 7870 XT which has never worked with the Linux open source drivers before. Some boards have "harvested" chips, meaning that some parts of the chip are disabled and fused, and it's sold for cheaper and under a different marketing name. On a harvested chip, any of the following can be disabled: - CUs (Compute Units) - RBs (Render Backend, aka. ROP) - Memory channels (ie. the chip has a lower bandwidth) - TCCs (ie. less L2 cache) Handle chips with harvested TCCs by patching the registers that configure how TCCs are mapped. If some TCCs are disabled, we need to make sure that the disabled TCCs are not used, and the remaining TCCs are used optimally. TCP_CHAN_STEER_LO/HI control which TCC is used by TCP channels. TCP_ADDR_CONFIG.NUM_TCC_BANKS controls how many channels are used. Note that the TCC configuration is highly relevant to performance. Suboptimal configuration (eg. CHAN_STEER=0) can significantly reduce gaming performance. For optimal performance: - Rely on the CHAN_STEER from the golden registers table, only skip disabled TCCs but keep the mapping order. - Limit NUM_TCC_BANKS to number of active TCCs to avoid thrashing, which performs better than using the same TCC twice. v2: - Also consider CGTS_USER_TCC_DISABLE for disabled TCCs.

2026-04-24drm/amdgpu/uvd3.1: Don't validate the firmware when already validatedTimur Kristóf
UVD 3.1 firmware validation seems to always fail after attempting it when it had already been validated. (This works similarly with the VCE 1.0 as well.) Don't attempt repeating the validation when it's already done. This caused issues in situations when the system isn't able to suspend the GPU properly and so the GPU isn't actually powered down. Then amdgpu would fail when calling the IP block resume function.

2026-04-24drm/amdgpu: avoid double drm_exec_fini() in userq validateHongyan Xu
When new_addition is true, amdgpu_userq_vm_validate() calls drm_exec_fini(&exec) before iterating over the collected HMM ranges and calling amdgpu_ttm_tt_get_user_pages(). If amdgpu_ttm_tt_get_user_pages() fails in that path, the code jumps to unlock_all and calls drm_exec_fini(&exec) a second time on the same exec object. drm_exec_fini() is not idempotent: it frees exec->objects and may also drop exec->contended and finalize the ww acquire context. Route that error path directly to the range cleanup once exec has already been finalized.

2026-04-24drm/amdgpu: fix zero-size GDS range init on RDNA4Arjan van de Ven
RDNA4 (GFX 12) hardware removes the GDS, GWS, and OA on-chip memory resources. The gfx_v12_0 initialisation code correctly leaves adev->gds.gds_size, adev->gds.gws_size, and adev->gds.oa_size at zero to reflect this. amdgpu_ttm_init() unconditionally calls amdgpu_ttm_init_on_chip() for each of these resources regardless of size. When the size is zero, amdgpu_ttm_init_on_chip() forwards the call to ttm_range_man_init(), which calls drm_mm_init(mm, 0, 0). drm_mm_init() immediately fires DRM_MM_BUG_ON(start + size <= start) -- trivially true when size is zero -- crashing the kernel during modprobe of amdgpu on an RX 9070 XT. Guard against this by returning 0 early from amdgpu_ttm_init_on_chip() when size_in_page is zero. This skips TTM resource manager registration for hardware resources that are absent, without affecting any other GPU type. DRM_MM_BUG_ON() only asserts if CONFIG_DRM_DEBUG_MM is enabled in the kernel config. This is apparently rarely enabled as these chips have been in the market for over a year and this issue was only reported now.

When no CMM is present, the rcrtc->cmm field is NULL, testing rcrtc->cmm->dev causes a NULL pointer dereference. This slipped through testing as all tests were run with the CMM present.

Note that a recent commit changed the default 10-bit dithering option to DITHER_OPTION_SPATIAL10 which improves the picture quality because it happens to look better, but is still not actually supported by DCE 6.x versions. When the color depth is 10-bit or more, just disable any kind of dithering options on DCE 6.x.
