2021-07-23drm/amdgpu: Clear doorbell interrupt status for Sienna CichlidChengzhe Liu3-0/+26
On Sienna Cichlid, in pass-through mode, if we unload the driver in BACO mode(RTPM), then the kernel would receive thousands of interrupts. That's because there is doorbell monitor interrupt on BIF, so KVM keeps injecting interrupts to the guest VM. So we should clear the doorbell interrupt status after BACO exit. v2: Modify coding style and commit message Signed-off-by: Chengzhe Liu <ChengZhe.Liu@amd.com> Reviewed-by: Luben Tuikov <luben.tuikov@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2021-07-23drm/amd/pm: Fix a bug communicating with the SMU (v5)Luben Tuikov2-47/+244
This fixes a bug which if we probe a non-existing I2C device, and the SMU returns 0xFF, from then on we can never communicate with the SMU, because the code before this patch reads and interprets 0xFF as a terminal error, and thus we never write 0 into register 90 to clear the status (and subsequently send a new command to the SMU.) It is not an error that the SMU returns status 0xFF. This means that the SMU executed the last command successfully (execution status), but the command result is an error of some sort (execution result), depending on what the command was. When doing a status check of the SMU, before we send a new command, the only status which precludes us from sending a new command is 0--the SMU hasn't finished executing a previous command, and 0xFC--the SMU is busy. This bug was seen as the following line in the kernel log, amdgpu: Msg issuing pre-check failed(0xff) and SMU may be not in the right state! when subsequent SMU commands, not necessarily related to I2C, were sent to the SMU. This patch fixes this bug. v2: Add a comment to the description of __smu_cmn_poll_stat() to explain why we're NOT defining the SMU FW return codes as macros, but are instead hard-coding them. Such a change, can be followed up by a subsequent patch. v3: The changes are, a) Add comments to break labels in __smu_cmn_reg2errno(). b) When an unknown/unspecified/undefined result is returned back from the SMU, map that to -EREMOTEIO, to distinguish failure at the SMU FW. c) Add kernel-doc to smu_cmn_send_msg_without_waiting(), smu_cmn_wait_for_response(), smu_cmn_send_smc_msg_with_param(). d) In smu_cmn_send_smc_msg_with_param(), since we wait for completion of the command, if the result of the completion is undefined/unknown/unspecified, we print that to the kernel log. v4: a) Add macros as requested, though redundant, to be removed when SMU consolidates for all ASICs--see comment in code. b) Get out if the SMU code is unknown. v5: Rename the macro names.
