From cee17a71656e9e1b5ffc01767844026550d5f4a9 Mon Sep 17 00:00:00 2001 From: Eugeniy Paltsev Date: Tue, 11 Jun 2019 20:21:59 +0300 Subject: drm/arcpgu: rework encoder search Instead of using non-standard "encoder-slave" property to find encoder let's find it by associated endpoint. While I'm on it add corresponding log message if we don't find any encoder and we assume that we use virtual LCD on the simulation platform.

Issue 1: In XGMI case amdgpu_device_lock_adev for other devices in hive was called to late, after access to their repsective schedulers. So relocate the lock to the begining of accessing the other devs. Issue 2: Using amdgpu_device_ip_need_full_reset to switch the device list from all devices in hive to the single 'master' device who owns this reset call is wrong because when stopping schedulers we iterate all the devices in hive but when restarting we will only reactivate the 'master' device. Also, in case amdgpu_device_pre_asic_reset conlcudes that full reset IS needed we then have to stop schedulers for all devices in hive and not only the 'master' but with amdgpu_device_ip_need_full_reset we already missed the opprotunity do to so. So just remove this logic and always stop and start all schedulers for all devices in hive. Also minor cleanup and print fix. v4: Minor coding style fix.

Problem: Under certain conditions, when some IP bocks take a RAS error, we can get into a situation where a GPU reset is not possible due to issues in RAS in SMU/PSP. Temporary fix until proper solution in PSP/SMU is ready: When uncorrectable error happens the DF will unconditionally broadcast error event packets to all its clients/slave upon receiving fatal error event and freeze all its outbound queues, err_event_athub interrupt will be triggered. In such case and we use this interrupt to issue GPU reset. THe GPU reset code is modified for such case to avoid HW reset, only stops schedulers, deatches all in progress and not yet scheduled job's fences, set error code on them and signals. Also reject any new incoming job submissions from user space. All this is done to notify the applications of the problem. v2: Extract amdgpu_amdkfd_pre/post_reset from amdgpu_device_lock/unlock_adev Move amdgpu_job_stop_all_jobs_on_sched to amdgpu_job.c Remove print param from amdgpu_ras_query_error_count v3: Update based on prevoius bug fixing patch to properly call amdgpu_amdkfd_pre_reset for other XGMI hive memebers.

This interface will remove sysfs file of df_cntr_avail function. The old behavior only create sysfs of df_cntr_avail in sw_init, but never remove it for lack of sw_fini interface. With this,driver will report create sysfs fail when it's loaded for the second time.

[how] remove GPIO close as part of GPIO destroy, this is unnecessary because GPIO is not shared, and GPIOs are generally closed after being opened Add tracking to HW access during destructor to make future issues easier to pinpoint, and block access to prevent hangs.

Underflow occurs because mem clk is not set high after disabling pstate switching. This behaviour occurs because some calculations assumed displays were synchronized. [How] Add a condition to check if timing sync is disabled so that synchronized vblank can be set to false.

Problem: amdgpu_ras_reserve_bad_pages was moved to amdgpu_ras_reset_gpu because writing to EEPROM during ASIC reset was unstable. But for ERREVENT_ATHUB_INTERRUPT amdgpu_ras_reset_gpu is called directly from ISR context and so locking is not allowed. Also it's irrelevant for this partilcular interrupt as this is generic RAS interrupt and not memory errors specific. Fix: Avoid calling amdgpu_ras_reserve_bad_pages if not in task context.

This avoid /dev/dri/card0 temporarily getting registered and then unregistered again, sending unwanted add / remove udev events to userspace. Specifically this avoids triggering the (userspace) bug fixed by this plymouth merge-request: https://gitlab.freedesktop.org/plymouth/plymouth/merge_requests/59 Note that despite that being an userspace bug, not sending unnecessary udev events is a good idea in general.

This seems to be wrong for both use cases. Use case one (suspend_enabe/disable): Those callbacks are used to mark a regulator device as enabled/disabled during suspend. Marking the regulator enabled during suspend is done by the LDOx_CONF/BUCKx_CONF bit within the LDOx_CONT/BUCKx_CONT registers. Setting this bit tells the DA9062 PMIC state machine to keep the regulator on in POWERDOWN mode and switch to suspend voltage. Use case two (get_mode): The get_mode callback is used to retrieve the active mode state. Since the regulator-setting-A is used for the active state and regulator-setting-B for the suspend state there is no need to check which regulator setting is active.
