Marking the context as guilty currently only makes the application which hits a single timeout problem to stop its rendering context entirely. All jobs submitted later are dropped from the guilty context. Lima runs on fairly underpowered hardware for modern standards and it is not entirely unreasonable that a rendering job may time out occasionally due to high system load or too demanding application stack. In this case it would be generally preferred to report the error but try to keep the application going. Other similar embedded GPU drivers don't make use of the guilty context flag. Now that there are reliability improvements to the lima timeout recovery handling, drop the guilty contexts to let the application keep running in this case. Signed-off-by:

There are several unexplained and unreproduced cases of rendering timeouts with lima, for which one theory is high IRQ latency coming from somewhere else in the system. This kind of occurrence may cause applications to trigger unnecessary resets of the GPU or even applications to hang if it hits an issue in the recovery path. Panfrost already does some special handling to account for such "spurious timeouts", it makes sense to have this in lima too to reduce the chance that it hit users. Signed-off-by:

This is required for reliable hard resets. Otherwise, doing a hard reset while a task is still running (such as a task which is being stopped by the drm_sched timeout handler) may result in random mmu write timeouts or lockups which cause the entire gpu to hang. Signed-off-by:

Lima gp jobs use an async reset to avoid having to wait for the soft reset right after a job. The soft reset is done at the end of a job and a reset_complete flag is expected to be set at the next job. However, in case the user runs into a job timeout from any application, a hard reset is issued to the hardware. This hard reset clears the reset_complete flag, which causes an error message to show up before the next job. This is probably harmless for the execution but can be very confusing to debug, as it blames a reset timeout on the next application to submit a job. Reset the async_reset flag when doing the hard reset so that we don't get that message. Signed-off-by:

Convert the remaining drm_debug_printer users over to drm_dbg_printer, as it can handle the cases without struct drm_device pointer, and also provides drm debug category and prefix support. Remove drm_debug_printer altogether. Signed-off-by:

We've lacked a device specific debug printer. Add one. Take category into account too. __builtin_return_address(0) is inaccurate here, so don't use it. If necessary, we can later pass __func__ to drm_dbg_printer() by wrapping it inside a macro. Signed-off-by:
