2021-08-26drm/amdkfd: Account for SH/SE count when setting up cu masks.Sean Keely2-21/+64
On systems with multiple SH per SE compute_static_thread_mgmt_se# is split into independent masks, one for each SH, in the upper and lower 16 bits. We need to detect this and apply cu masking to each SH. The cu mask bits are assigned first to each SE, then to alternate SHs, then finally to higher CU id. This ensures that the maximum number of SPIs are engaged as early as possible while balancing CU assignment to each SH. v2: Use max SH/SE rather than max SH in cu_per_sh. v3: Fix comment blocks, ensure se_mask is initially zero filled, and correctly assign se.sh.cu positions to unset bits in cu_mask.

2021-08-25drm/panfrost: Simplify lock_region calculationAlyssa Rosenzweig1-14/+5
In lock_region, simplify the calculation of the region_width parameter. This field is the size, but encoded as ceil(log2(size)) - 1. ceil(log2(size)) may be computed directly as fls(size - 1). However, we want to use the 64-bit versions as the amount to lock can exceed 32-bits. This avoids undefined (and completely wrong) behaviour when locking all memory (size ~0). In this case, the old code would "round up" ~0 to the nearest page, overflowing to 0. Since fls(0) == 0, this would calculate a region width of 10 + 0 = 10. But then the code would shift by (region_width - 11) = -1. As shifting by a negative number is undefined, UBSAN flags the bug. Of course, even if it were defined the behaviour is wrong, instead of locking all memory almost none would get locked. The new form of the calculation corrects this special case and avoids the undefined behaviour.

2021-08-24drm/amdgpu/OLAND: clip the ref divider max valueShashank Sharma3-9/+16
This patch limits the ref_div_max value to 100, during the calculation of PLL feedback reference divider. With current value (128), the produced fb_ref_div value generates unstable output at particular frequencies. Radeon driver limits this value at 100. On Oland, when we try to setup mode 2048x1280@60 (a bit weird, I know), it demands a clock of 221270 Khz. It's been observed that the PLL calculations using values 128 and 100 are vastly different, and look like this: +------------------------------------------+ |Parameter |AMDGPU |Radeon | | | | | +-------------+----------------------------+ |Clock feedback | | |divider max | 128 | 100 | |cap value | | | | | | | | | | | +------------------------------------------+ |ref_div_max | | | | | 42 | 20 | | | | | | | | | +------------------------------------------+ |ref_div | 42 | 20 | | | | | +------------------------------------------+ |fb_div | 10326 | 8195 | +------------------------------------------+ |fb_div | 1024 | 163 | +------------------------------------------+ |fb_dev_p | 4 | 9 | |frac fb_de^_p| | | +----------------------------+-------------+ With ref_div_max value clipped at 100, AMDGPU driver can also drive videmode 2048x1280@60 (221Mhz) and produce proper output without any blanking and distortion on the screen. PS: This value was changed from 128 to 100 in Radeon driver also, here: https://github.com/freedesktop/drm-tip/commit/4b21ce1b4b5d262e7d4656b8ececc891fc3cb806 V1: Got acks from: Acked-by: Alex Deucher <alexander.deucher@amd.com> Acked-by: Christian König <christian.koenig@amd.com> V2: - Restricting the changes only for OLAND, just to avoid any regression for other cards. - Changed unsigned -> unsigned int to make checkpatch quiet.

Building a randconfig here triggered: ERROR: modpost: "pm_suspend_target_state" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! because the module export of that symbol happens in kernel/power/suspend.c which is enabled with CONFIG_SUSPEND. The ifdef guards in amdgpu_acpi_is_s0ix_supported(), however, test for CONFIG_PM_SLEEP which is defined like this: config PM_SLEEP def_bool y depends on SUSPEND || HIBERNATE_CALLBACKS and that randconfig has: # CONFIG_SUSPEND is not set CONFIG_HIBERNATE_CALLBACKS=y leading to the module export missing.

2021-08-20drm/amdgpu: Cancel delayed work when GFXOFF is disabledMichel Dänzer2-17/+30
schedule_delayed_work does not push back the work if it was already scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms after the first time GFXOFF was disabled and re-enabled, even if GFXOFF was disabled and re-enabled again during those 100 ms. This resulted in frame drops / stutter with the upcoming mutter 41 release on Navi 14, due to constantly enabling GFXOFF in the HW and disabling it again (for getting the GPU clock counter). To fix this, call cancel_delayed_work_sync when the disable count transitions from 0 to 1, and only schedule the delayed work on the reverse transition, not if the disable count was already 0. This makes sure the delayed work doesn't run at unexpected times, and allows it to be lock-free. v2: * Use cancel_delayed_work_sync & mutex_trylock instead of mod_delayed_work. v3: * Make amdgpu_device_delay_enable_gfx_off lock-free (Christian König) v4: * Fix race condition between amdgpu_gfx_off_ctrl incrementing adev->gfx.gfx_off_req_count and amdgpu_device_delay_enable_gfx_off checking for it to be 0 (Evan Quan) Cc: stable@vger.kernel.org Reviewed-by: Evan Quan <evan.quan@amd.com> Reviewed-by: Lijo Lazar <lijo.lazar@amd.com> # v3 Acked-by: Christian König <christian.koenig@amd.com> # v3 Signed-off-by: Michel Dänzer <mdaenzer@redhat.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
