Each slot holds the job's Tile State Data +Array (TSDA) at its start, followed by the tile allocation pool. + +While the tile allocation pool is only walked by the render thread +through branches the binner generated during the current job, the +TSDA is the PTB's own per-tile bookkeeping and is consumed by the +hardware itself. Although the kernel sets the "Auto-initialise Tile +State Data Array" flag in the tile binning mode configuration, the +PTB demonstrably still acts on stale tile state left by the slot's +previous user: the binner ends up creating invalid command streams +with invalid primitive streams and branches, which can cause GPU hangs +as observed in [1][2]. + +Zero the TSDA when the job's binning slot is configured. This clears +48 bytes per tile (~24KB for a 1080p frame) in the submission path, and +guarantees the PTB never sees another job's tile state. + +The tile count is only checked for being non-zero today, so the 8-bit +fields it comes from can describe a tile state array almost six times +larger than the slot it has to live in. Bound it before the slot is +handed out, since such size decides how much of the slot is left for +the tile alloc pool. + +Link: https://github.com/raspberrypi/linux/issues/3221 [1] +Link: https://github.com/raspberrypi/linux/issues/5780 [2] +Fixes: 553c942f8b2c ("drm/vc4: Allow using more than 256MB of CMA memory.") +Cc: stable@vger.kernel.org +Reviewed-by: Iago Toral Quiroga +Link: https://patch.msgid.link/20260727-vc4-bin-oom-fixes-v2-2-0d8a5eddc7c9@igalia.com +Signed-off-by: Maíra Canal +Signed-off-by: Greg Kroah-Hartman +--- + drivers/gpu/drm/vc4/vc4_validate.c | 29 +++++++++++++++++++++++------ + 1 file changed, 23 insertions(+), 6 deletions(-) + +--- a/drivers/gpu/drm/vc4/vc4_validate.c ++++ b/drivers/gpu/drm/vc4/vc4_validate.c +@@ -379,6 +379,23 @@ validate_tile_binning_config(VALIDATE_AR + return -EINVAL; + } + ++ /* The tile state data array is 48 bytes per tile, and we put it at ++ * the start of a BO containing both it and the tile alloc. ++ */ ++ tile_state_size = 48 * tile_count; ++ ++ /* Since the tile alloc array will follow us, align. */ ++ tile_state_size = roundup(tile_state_size, 4096); ++ ++ /* Reject configurations whose tile state would leave no room for ++ * the tile alloc pool that follows it in the slot. ++ */ ++ if (tile_state_size >= vc4->bin_alloc_size) { ++ DRM_DEBUG("Tile binning config of %dx%d too large\n", ++ exec->bin_tiles_x, exec->bin_tiles_y); ++ return -EINVAL; ++ } ++ + bin_slot = vc4_v3d_get_bin_slot(vc4); + if (bin_slot < 0) { + if (bin_slot != -EINTR && bin_slot != -ERESTARTSYS) { +@@ -394,13 +411,13 @@ validate_tile_binning_config(VALIDATE_AR + exec->bin_slots |= BIT(bin_slot); + bin_addr = vc4->bin_bo->base.paddr + bin_slot * vc4->bin_alloc_size; + +- /* The tile state data array is 48 bytes per tile, and we put it at +- * the start of a BO containing both it and the tile alloc. +- */ +- tile_state_size = 48 * tile_count; ++ exec->tile_alloc_offset = bin_addr + tile_state_size; + +- /* Since the tile alloc array will follow us, align. */ +- exec->tile_alloc_offset = bin_addr + roundup(tile_state_size, 4096); ++ /* The TSDA area must be zeroed out before use, otherwise the PTB might ++ * consume a stale tile state. ++ */ ++ memset(vc4->bin_bo->base.vaddr + bin_slot * vc4->bin_alloc_size, 0, ++ tile_state_size); + + *(uint8_t *)(validated + 14) = + ((flags & ~(VC4_BIN_CONFIG_ALLOC_INIT_BLOCK_SIZE_MASK | diff --git a/queue-5.15/series b/queue-5.15/series index 75e67941a9..b46a71752b 100644 --- a/queue-5.15/series +++ b/queue-5.15/series @@ -343,3 +343,16 @@ net-openvswitch-fix-potential-uaf-on-meter-attach-failure.patch net-openvswitch-fix-skb-leak-on-flow-key-update-failure-during-ct.patch i2c-jz4780-cache-host-clock-rate-at-probe-to-prevent-ccf-prepare_lock-deadlock.patch i2c-imx-cancel-hrtimer-before-clearing-slave-pointer.patch +can-c_can-c_can_chip_config-keep-controller-in-init-mode-until-bittiming-is-configured.patch +can-ems_usb-validate-cpc-message-lengths.patch +can-etas_es58x-es58x_read_bulk_callback-fix-rx-buffer-leak-on-urb-resubmit-failure.patch +can-j1939-transport-j1939_session_fresh_new-initialize-receive-buffer.patch +can-kvaser_usb-kvaser_usb_hydra_get_busparams-fix-memory-leak-in-kvaser_usb_hydra_get_busparams.patch +can-kvaser_usb_leaf-kvaser_usb_leaf_wait_cmd-validate-received-command-extents.patch +can-softing-fw_parse-validate-firmware-record-spans.patch +can-peak_usb-add-bounds-check-for-usb-channel-index.patch +can-peak_usb-peak_usb_start-fix-double-free-of-transfer-buffer-on-urb-submit-error.patch +can-peak_usb-validate-ucan-receive-record-lengths.patch +drm-vc4-zero-the-tile-state-data-array-before-each-bin-job.patch +drm-amdgpu-restore-umd-profile-pstate-after-runtime-resume.patch +drm-amdgpu-cap-gtt-size-to-physical-ram-on-apus.patch
