2022-02-17drm/amdgpu: fix amdgpu_ras_block_late_init error handlerTom Rix1-6/+5
Clang build fails with amdgpu_ras.c:2416:7: error: variable 'ras_obj' is used uninitialized whenever 'if' condition is true if (adev->in_suspend || amdgpu_in_reset(adev)) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ amdgpu_ras.c:2453:6: note: uninitialized use occurs here if (ras_obj->ras_cb) ^~~~~~~ There is a logic error in the error handler's labels. ex/ The sysfs: is the last goto label in the normal code but is the middle of error handler. Rework the error handler. cleanup: is the first error, so it's handler should be last. interrupt: is the second error, it's handler is next. interrupt: handles the failure of amdgpu_ras_interrupt_add_hander() by calling amdgpu_ras_interrupt_remove_handler(). This is wrong, remove() assumes the interrupt has been setup, not torn down by add(). Change the goto label to cleanup. sysfs is the last error, it's handler should be first. sysfs: handles the failure of amdgpu_ras_sysfs_create() by calling amdgpu_ras_sysfs_remove(). But when the create() fails there is nothing added so there is nothing to remove. This error handler is not needed. Remove the error handler and change goto label to interrupt.

The `program_aspm` callback is already guarded for aspm, but the `enable_aspm` callback doesn't follow the module parameter. Update it to use the helper `amdgpu_device_should_use_aspm`.

2022-02-17drm/amd: Refactor `amdgpu_aspm` to be evaluated per deviceMario Limonciello8-8/+31
Evaluating `pcie_aspm_enabled` as part of driver probe has the implication that if one PCIe bridge with an AMD GPU connected doesn't support ASPM then none of them do. This is an invalid assumption as the PCIe core will configure ASPM for individual PCIe bridges. Create a new helper function that can be called by individual dGPUs to react to the `amdgpu_aspm` module parameter without having negative results for other dGPUs on the PCIe bus.

commit 0064b0ce85bb ("drm/amd/pm: enable ASPM by default") enabled ASPM by default but a variety of hardware configurations it turns out that this caused a regression. * PPC64LE hardware does not support ASPM at a hardware level. CONFIG_PCIEASPM is often disabled on these architectures. * Some dGPUs on ALD platforms don't work with ASPM enabled and PCIe subsystem disables it Check with the PCIe subsystem to see that ASPM has been enabled or not.

This patch handles the GPU recovery failure in sriov environment by retrying the reset if the first reset fails. To determine the condition of retry, a new macro AMDGPU_RETRY_SRIOV_RESET is added which returns true if failure is due to ETIMEDOUT, EINVAL or EBUSY, otherwise return false.A new macro AMDGPU_MAX_RETRY_LIMIT is used to limit the retry to 2. It also handles the return status in Post Asic Reset by updating the return code with asic_reset_res and eventually return the return code in amdgpu_job_timedout().
