drm/radeon: fix r100_copy_blit for large BOs

2026-06-17T22:19:00+00:00

r100_copy_blit() copies BOs as 1024-pixel-wide ARGB8888 blits, so one GPU page becomes one blit row. Large copies are split into chunks of at most 8191 rows. The kernel register header names the packet coordinate dwords SRC_Y_X and DST_Y_X. In the BITBLT_MULTI description in R5xx_Acceleration_v1.5.pdf docs, these correspond to [SRC_X1 | SRC_Y1] and [DST_X1 | DST_Y1], which are signed 13-bit coordinates in the -8192..8191 range. The old code kept SRC/DST_PITCH_OFFSET at the BO base and used SRC_Y_X/DST_Y_X as the chunk address, so large BO moves could exceed that coordinate range. Compute per-chunk SRC/DST_PITCH_OFFSET bases and emit zero source and destination coordinates. r100_copy_blit() already packs SRC/DST_PITCH_OFFSET as pitch plus base offset, so large chunk addresses belong there rather than in the coordinate fields. This fixes Prison Architect corruption with 4096x4096 mipped textures after they are evicted to GTT under memory pressure on RV530.

drm/radeon/radeon_connectors: remove radeon_connector_free_edid

2026-05-27T14:51:19+00:00

Since we are using struct drm_edid, we can call drm_edid_free directly. Also make sure to set the pointer to NULL afterwards. Signed-off-by: Joshua Peisach Signed-off-by: Alex Deucher

drm/radeon/radeon_connectors: use struct drm_edid instead of struct edid

2026-05-27T14:51:15+00:00

This was done with amdgpu, just bringing the same patch to radeon. The goal of this is to stop using the deprecated edid functions, specifically drm_connector_update_edid_property. Switch to struct drm_edid and the appropriate function replacements for the new type. Also, for audio, use the raw edid for SADB allocations and for equivalent drm_edid_is_digital expressions.

drm/radeon/evergreen_cs: Add missing NULL prefix check in surface check

2026-05-19T15:49:56+00:00

'evergreen_surface_check' is called with a NULL warning prefix when handling potentially recoverable issues or just to compute the alignment requirements, and 'evergreen_surface_check' is called again in case of failure (with the correct prefix, as opposed to NULL), therefore, the initial check must not print a warning, because the surface may be accepted successfully after having been corrected, however if it isn't, the final check will print the warning anyway. The surface check functions specific to array modes already implement this behavior, but the 'evergreen_surface_check' function itself doesn't. This is also supposed to fix the "'%s' directive argument is null [-Werror=format-overflow=]" compiler warning.

drm/radeon: fix memory leak in radeon_ring_restore() on lock failure

2026-04-17T19:41:16+00:00

radeon_ring_restore() takes ownership of the data buffer allocated by radeon_ring_backup(). The caller (radeon_gpu_reset()) only frees it in the non-restore branch; in the restore branch it relies on radeon_ring_restore() to free it. If radeon_ring_lock() fails, the function returned early without calling kvfree(data), leaking the ring backup buffer on every GPU reset that fails at the lock stage. During repeated GPU resets this causes cumulative kernel memory exhaustion. Free data before returning the error.

drm/radeon: fix integer overflow in radeon_align_pitch()

2026-04-17T19:41:16+00:00

radeon_align_pitch() has the same kind of overflow issue as the old amdgpu helper: both the alignment round-up add and the final 'aligned * cpp' calculation can overflow signed int. If that wraps, radeon_mode_dumb_create() can end up returning an invalid pitch or creating a zero-sized dumb buffer. Fix this by using check_add_overflow() for the alignment round-up and check_mul_overflow() for the final pitch calculation, returning 0 on overflow. Also reject zero pitch and size in radeon_mode_dumb_create(). Found via AST-based call-graph analysis using sqry.
