13 daysdrm/amd/pm: Add fine grained flag to SMU v13.0.6Lijo Lazar1-0/+1
[ Upstream commit 47a5dfc8add4e60ff1ddc312f79998e70cbb0c09 ] Gfx clock is fine grained on SMU v13.0.6/12 SOCs. Add the flag to report clock frequencies correctly.

13 daysdrm/amd/pm/smu7: Add SCLK cap for quirky Hawaii boardTimur Kristóf2-4/+27
[ Upstream commit 4724bc5b8d78c34b993594f9406135408ccb312a ] On a specific Radeon R9 390X board, the GPU can "randomly" hang while gaming. 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.

[ Upstream commit baf28ec5795c077406d6f52b8ad39e614153bce6 ] In ci_populate_dw8() we currently just read a value from the SMU and then throw it away. Instead of throwing away the value, we should use it to fill other fields in DW8 (like radeon). Otherwise the value of the other fiels is just cleared when we copy this data to the SMU later.

13 daysdrm/amd/pm/smu7: Fix SMU7 voltage dependency on display clockTimur Kristóf2-3/+86
[ Upstream commit 0138610c14130425be53423b35336561829965e0 ] The DCE (display controller engine) requires a minimum voltage in order to function correctly, depending on which clock level it currently uses. 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.

13 daysdrm/amd/pm/ci: Disable MCLK DPM on problematic CI ASICsTimur Kristóf1-0/+15
[ Upstream commit 9851f29cb06c09f7dad3867d8b0feec3fc71b6c8 ] There are two known cases where MCLK DPM can causes issues: Radeon R9 M380 found in iMac computers from 2015. 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.

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts.

Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2026-02-12drm/amd/pm: send unload command to smu during modprobe -r amdgpuKenneth Feng3-12/+4
Send unload command to smu during modprobe -r amdgpu for smu 13/14. 1. This can fix the high voltage/temperatue issue after driver is unloaded. 2. Reloading driver could fail but with the debug port based mode1 reset during driver is reloaded, it is good and safe.

2026-02-12drm/amd/pm: use sysfs_streq for string matching in amdgpu_pmYang Wang1-15/+14
The driver uses strncmp() to compare sysfs attribute strings, which does not handle trailing newlines and lacks NULL safety. sysfs_streq() is the recommended function for sysfs string equality checks in the kernel, providing safer and more correct behavior. replace strncmp() with sysfs_streq() in drivers/gpu/drm/amd/pm/amdgpu_pm.c Signed-off-by: Yang Wang <kevinyang.wang@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
