From de1ef4ffd70e1d15f0bf584fd22b1f28cbd5e2ec Mon Sep 17 00:00:00 2001 From: Junrui Luo Date: Tue, 24 Mar 2026 17:39:02 +0800 Subject: [PATCH 01/71] drm/amdgpu: validate doorbell_offset in user queue creation amdgpu_userq_get_doorbell_index() passes the user-provided doorbell_offset to amdgpu_doorbell_index_on_bar() without bounds checking. An arbitrarily large doorbell_offset can cause the calculated doorbell index to fall outside the allocated doorbell BO, potentially corrupting kernel doorbell space. Validate that doorbell_offset falls within the doorbell BO before computing the BAR index, using u64 arithmetic to prevent overflow.

To handle this, we allocate an enlarged MQD buffer where the first page is used as the MQD and the remaining pages store the control stack. Although these regions share the same BO, they require different memory types: the MQD must be UC (uncached), while the control stack must be NC (non-coherent), matching the behavior when the control stack is allocated in user space. This logic works correctly on systems where the CPU page size matches the GPU page size (4K). However, the current implementation aligns both the MQD and the control stack to the CPU PAGE_SIZE. On systems with a larger CPU page size, the entire first CPU page is marked UC—even though that page may contain multiple GPU pages. The GPU treats the second 4K GPU page inside that CPU page as part of the control stack, but it is incorrectly mapped as UC. This patch fixes the issue by aligning both the MQD and control stack sizes to the GPU page size (4K). The first 4K page is correctly marked as UC for the MQD, and the remaining GPU pages are marked NC for the control stack. This ensures proper memory type assignment on systems with larger CPU page sizes.

Timeout is caused by driver fails validate_bandwidth() during atomic_commit_tail but passes atomic_check. Under further analysis, indicates the delta of atomic_check and atomic_commit_tail are dc->current_state->bw_ctx.dml.soc.sr_exit_time_us and dc->current_state->bw_ctx.dml.soc.sr_enter_plus_exit_time_us. We set validate_mode as DC_VALIDATE_MODE_ONLY while calling dc_validate_global_state() at atomic_check, but set mode as DC_VALIDATE_MODE_AND_PROGRAMMING during atomic_commit_tail. If dc_validate_mode set as DC_VALIDATE_MODE_ONLY, validate_bandwidth() will skip the wm and dlg calculation. During commit_tail, validate_bandwidth() is called with dc_validate_mode set as DC_VALIDATE_MODE_AND_PROGRAMMING and dc_state->bw_ctx.dml.soc.sr_exit_time_us might get modified after the wm_calculation and stored into dc->current_state. Which means dc->current_state->bw_ctx.dml.soc.sr_exit_time_us might not aligned with the one stored in dm_state->context. That causes duplicated dm_state->context not aligned with dc->current_state, and might have bandwidth validation pass in atomic_check and fail in commit_tail later. [How] When the issue occurs, it fails dml_get_voltage_level() with the condition dm_allow_self_refresh_and_mclk_switch but pass with the condition dm_allow_self_refresh. However, we should support p-state. So we should not pass validate_bandwidth by allowing self refresh only. Change the policy under DCN21.

If the signal type is DVI then the OTG can become stuck on pre DCN401 ASIC when DPMS off occurs because the OTG remains running but the PHY transmitter is disabled. [How] There exists logic to keep track of the OTG running refcount on the link to determine if the link needs to go to PLL_EN instead of TX_EN but the logic only checks for HDMI TMDS on older ASIC. DVI is still a TMDS signal type so the constraint should also apply. Replace the checks for dc_is_hdmi_tmds_signal with dc_is_tmds_signal to cover both HDMI and DVI for the symclk refcount workaround.

When num_clk_values is 0, this results in accessing array index -1, which wraps to 255 for unsigned types, causing out-of-bounds memory access and potential crashes. [How] Add proper bounds checking using ternary operators to guard all num_clk_values-1 array accesses. When num_clk_values is 0, return 0 as fallback value instead of accessing invalid memory. This prevents buffer overflows while maintaining backward compatibility and provides sensible default behavior for empty clock tables.

As part of this, the driver selects a watermark table based on the memory type (DDR4, LPDDR4, LPDDR5) from ctx->dc_bios->integrated_info. The display pipeline continuously reads pixel data from memory, processes it (such as scaling, color conversion, and blending), and sends it to the screen. To keep this pipeline running smoothly, the driver must ensure there is enough memory bandwidth and that clocks are increased when needed. Watermark tables define when the GPU should increase clocks to ensure there is enough bandwidth to feed pixel data without underflow. However, ctx->dc_bios->integrated_info is dereferenced without checking for NULL in multiple clk_mgr_construct() implementations. On some platforms, BIOS may not provide this information, and accessing it directly can cause a NULL pointer dereference during initialization. Fix this by adding a NULL check before accessing integrated_info. If integrated_info is not available, the driver safely falls back to default watermark tables.

These variables are meant as global configs, not to by dynamically modified. Modifying them dynamically prevents us from enabling/disabling functionality for debug purposes and can easily lead to bad things since we're not operating on the current state but on DC-wide variables. Instead we should look at the existing split4mpc decision in dcn20_validate_apply_split_flags and make the decision there, if the global config.enable_4to1MPC is set to true for the DCN version we're running. This fixes corruption that is observed when running a new IGT kms_colorop test for color-space-conversion that uses a YUV plane and outputs to a writeback connector.

Add != 0 for bool assignments from uint32_t bitfield reads. - dmub_reg.c: Cast va_arg shift value to uint8_t with ASSERT guard before passing to set_reg_field_value_masks(). - dmub_srv.c: Widen num_pending to uint64_t to match uint64_t arithmetic; use != 0 for bool assignments from unsigned expressions. No functional change intended.

This increases maintenance overhead and potential for bugs. [How] Expose clock constants and internal functions in header for sharing. Remove duplicate implementations and update function pointers to use shared functions. Refactor remaining variant-specific functions to use shared constants and helper functions. Add compatibility comments for hardware differences.

To do this properly, the FPU guards must be used in a file that is not compiled as a FPU unit. If the guards are used in a file that is a FPU unit, other sections in the file that aren't guarded may be end up being compiled to use FPU operations. [How] Added DC_FP_START and DC_FP_END to DC functions that call DML functions using FPU.

From 4bb2f0721ed8a2a70f864b9358bd6cd4d92199b3 Mon Sep 17 00:00:00 2001 From: Rafal Ostrowski Date: Wed, 18 Feb 2026 16:19:47 +0100 Subject: [PATCH 42/71] drm/amd/display: Move FPU Guards From DML To DC - Part 2 [Why] FPU guards (DC_FP_START/DC_FP_END) are required to wrap around code that can manipulates floats. To do this properly, the FPU guards must be used in a file that is not compiled as a FPU unit. If the guards are used in a file that is a FPU unit, other sections in the file that aren't guarded may be end up being compiled to use FPU operations. [How] Removed DC_FP_START and DC_FP_END.

To do this properly, the FPU guards must be used in a file that is not compiled as a FPU unit. If the guards are used in a file that is a FPU unit, other sections in the file that aren't guarded may be end up being compiled to use FPU operations. [How] Added DC_FP_START and DC_FP_END to DC functions that call DML functions using FPU.

Compiler warnings in dmub [Why] Resolve compiler warnings by marking unused parameters explicitly. [How] In .c and .h files, keep parameter names in signatures and add a line with`(void)param;` inside the function body Preserved function signatures and avoids breaking code paths that may reference the parameter under conditional compilation.

It can also spam DMUB command submission in a way that prevents it from servicing other requestors. [How] Introduce the Idle State Manager (ISM) to amdgpu. It maintains a finite state machine that uses a hysteresis to determine if a delay should be inserted between a caller allowing idle, and when the actual idle optimizations are programmed. A second timer is also introduced to enable static screen optimizations (SSO) such as PSR1 and Replay low HZ idle mode. Rapid SSO enable/disable can have a negative power impact on some low hz video playback, and can introduce user lag for PSR1 (due to up to 3 frames of sync latency). This effectively rate-limits idle optimizations, based on hysteresis. This also replaces the existing delay logic used for PSR1, allowing drm_vblank_crtc_config.disable_immediate = true, and thus allowing drm_crtc_vblank_restore(). v2: * Loosen criteria for ISM to exit idle optimizations; it failed to exit idle correctly on cursor updates when there are no drm_vblank requestors, * Document default_ism_config * Convert pr_debug to trace events to reduce overhead on frequent codepaths * checkpatch.pl fixes Link: https://gitlab.freedesktop.org/drm/amd/-/issues/4527 Link: https://gitlab.freedesktop.org/drm/amd/-/issues/3709 Fixes: 58a261bfc967 ("drm/amd/display: use a more lax vblank enable policy for older ASICs") Signed-off-by: Ray Wu Signed-off-by: Leo Li Reviewed-by: Mario Limonciello (AMD) Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h | 5 + .../gpu/drm/amd/display/amdgpu_dm/Makefile | 3 +- .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 34 +- .../amd/display/amdgpu_dm/amdgpu_dm_crtc.c | 90 +-- .../amd/display/amdgpu_dm/amdgpu_dm_crtc.h | 6 + .../drm/amd/display/amdgpu_dm/amdgpu_dm_ism.c | 598 ++++++++++++++++++ .../drm/amd/display/amdgpu_dm/amdgpu_dm_ism.h | 151 +++++ .../amd/display/amdgpu_dm/amdgpu_dm_plane.c | 16 + .../amd/display/amdgpu_dm/amdgpu_dm_trace.h | 63 ++ 9 files changed, 903 insertions(+), 63 deletions(-) create mode 100644 drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_ism.c create mode 100644 drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_ism.h diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h index 90352284c5ee..51ab1a332615 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h @@ -44,6 +44,7 @@ #include #include "modules/inc/mod_freesync.h" #include "amdgpu_dm_irq_params.h" +#include "amdgpu_dm_ism.h" struct amdgpu_bo;

This patch fixes the issue by aligning the control stack size to AMDGPU_GPU_PAGE_SIZE instead of PAGE_SIZE, so the control stack size will not be 64 KB on systems with a 64 KB page size and queue preemption works correctly. Additionally, In the current code, wg_data_size is aligned to PAGE_SIZE, which can waste memory if the system page size is large. In this patch, wg_data_size is aligned to AMDGPU_GPU_PAGE_SIZE. The cwsr_size, calculated from wg_data_size and the control stack size, is aligned to PAGE_SIZE.

The SMU in this GPU just hangs as soon as we send it the PPSMC_MSG_MCLKDPM_Enable command, even when MCLK switching is disabled, and even when we only populate one MCLK DPM level. Apply workaround to all devices with the same subsystem ID. Radeon R7 260X due to old memory controller microcode. We only flash the MC ucode when it isn't set up by the VBIOS, therefore there is no way to make sure that it has the correct ucode version. I verified that this patch fixes the SMU hang on the R9 M380 which would previously fail to boot. This also fixes the UVD initialization error on that GPU which happened because the SMU couldn't ungate the UVD after it hung.

Add a new table that contains display clock frequency levels and the corresponding required voltages. The clock frequency levels are taken from DC (and the old radeon driver's voltage dependency table for CI in cases where its values were lower). The voltage levels are taken from the following function: phm_initializa_dynamic_state_adjustment_rule_settings(). Furthermore, in case of CI, call smu7_patch_vddc() on the new table to account for leakage voltage (like in radeon). Use the display clock value from amd_pp_display_configuration to look up the voltage level needed by the DCE. Send the voltage to the SMU via the PPSMC_MSG_VddC_Request command. The previous implementation of this feature was non-functional because it relied on a "dal_power_level" field which was never assigned; and it was not at all implemented for CI ASICs. I verified this on a Radeon R9 M380 which previously booted to a black screen with DC enabled (default since Linux 6.19), but now works correctly.

Initially I thought this was a RADV bug and tried to work around this in Mesa: commit 8ea08747b86b ("radv: Mitigate GPU hang on Hawaii in Dota 2 and RotTR") However, I got some feedback from other users who are reporting that the above mitigation causes a significant performance regression for them, and they didn't experience the hang on their GPU in the first place. After some further investigation, it turns out that the problem is that the highest SCLK DPM level on this board isn't stable. Lowering SCLK to 1040 MHz (from 1070 MHz) works around the issue, and has a negligible impact on performance compared to the Mesa patch. (Note that increasing the voltage can also work around it, but we felt that lowering the SCLK is the safer option.) To solve the above issue, add an "sclk_cap" field to smu7_hwmgr and set this field for the affected board. The capped SCLK value correctly appears on the sysfs interface and shows up in GUI tools such as LACT.
