2021-03-04drm/amdgpu: Prevent shift wrapping in amdgpu_read_mask()Dan Carpenter1-3/+3
[ Upstream commit c915ef890d5dc79f483e1ca3b3a5b5f1a170690c ] If the user passes a "level" value which is higher than 31 then that leads to shift wrapping. The undefined behavior will lead to a syzkaller stack dump.

2020-07-29drm/amdgpu: Fix NULL dereference in dpm sysfs handlersPaweł Gronowski1-6/+3
commit 38e0c89a19fd13f28d2b4721035160a3e66e270b upstream. NULL dereference occurs when string that is not ended with space or newline is written to some dpm sysfs interface (for example pp_dpm_sclk). This happens because strsep replaces the tmp with NULL if the delimiter is not present in string, which is then dereferenced by tmp[0]. Reproduction example: sudo sh -c 'echo -n 1 > /sys/class/drm/card0/device/pp_dpm_sclk' Signed-off-by: Paweł Gronowski <me@woland.xyz> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2020-06-22drm/amd/powerpay: Disable gfxoff when setting manual mode on picasso and ravenchen gong1-0/+9
[ Upstream commit cbd2d08c7463e78d625a69e9db27ad3004cbbd99 ] [Problem description] 1. Boot up picasso platform, launches desktop, Don't do anything (APU enter into "gfxoff" state) 2. Remote login to platform using SSH, then type the command line: sudo su -c "echo manual > /sys/class/drm/card0/device/power_dpm_force_performance_level" sudo su -c "echo 2 > /sys/class/drm/card0/device/pp_dpm_sclk" (fix SCLK to 1400MHz) 3. Move the mouse around in Window 4. Phenomenon : The screen frozen Tester will switch sclk level during glmark2 run time. APU will enter "gfxoff" state intermittently during glmark2 run time. The system got hanged if fix GFXCLK to 1400MHz when APU is in "gfxoff" state. [Debug] 1. Fix SCLK to X MHz 1400: screen frozen, screen black, then OS will reboot. 1300: screen frozen. 1200: screen frozen, screen black. 1100: screen frozen, screen black, then OS will reboot. 1000: screen frozen, screen black. 900: screen frozen, screen black, then OS will reboot. 800: Situation Nomal, issue disappear. 700: Situation Nomal, issue disappear. 2. SBIOS setting: AMD CBS --> SMU Debug Options -->SMU Debug --> "GFX DLDO Psm Margin Control": 50 : Situation Nomal, issue disappear. 45 : Situation Nomal, issue disappear. 40 : Situation Nomal, issue disappear. 35 : Situation Nomal, issue disappear. 30 : screen black. 25 : screen frozen, then blurred screen. 20 : screen frozen. 15 : screen black. 10 : screen frozen. 5 : screen frozen, then blurred screen. 3. Disable GFXOFF feature Situation Nomal, issue disappear. [Why] Through a period of time debugging with Sys Eng team and SMU team, Sys Eng team said this is voltage/frequency marginal issue not a F/W or H/W bug. This experiment proves that default targetPsm [for f=1400MHz] is not sufficient when GFXOFF is enabled on Picasso. SMU team think it is an odd test conditions to force sclk="1400MHz" when GPU is in "gfxoff" state，then wake up the GFX. SCLK should be in the "lowest frequency" when gfxoff. [How] Disable gfxoff when setting manual mode. Enable gfxoff when setting other mode(exiting manual mode) again. By the way, from the user point of view, now that user switch to manual mode and force SCLK Frequency, he don't want SCLK be controlled by workload.It becomes meaningless to "switch to manual mode" if APU enter "gfxoff" due to lack of workload at this point. Tips: Same issue observed on Raven.

2020-06-22drm/amdgpu: Init data to avoid oops while reading pp_num_states.limingyu1-1/+4
[ Upstream commit 6f81b2d047c59eb77cd04795a44245d6a52cdaec ] For chip like CHIP_OLAND with si enabled(amdgpu.si_support=1), the amdgpu will expose pp_num_states to the /sys directory. In this moment, read the pp_num_states file will excute the amdgpu_get_pp_num_states func.
