2023-06-09drm/amd/display: Program OTG vtotal min/max selectors unconditionally for DCN1+Aurabindo Pillai2-12/+13
For FPO/FAMS, DMCUB will try to change the output timings by writing to the OTG registers. However, the timings written directly to the OTG registers will not be honoured unless VMIN/VMAX selector registers are programmed with the right bits and trigger source is selected correctly. Proper solution needs to go into DMCUB but will require additional state tracking to ensure that the selectors are set and reset correctly as per driver state. Until fix is merged into firmware, apply the workaround in driver to unconditionally write OTG vmin/vmax selectors.

This reverts commit 047783cdd5f604d87398236beb4971abb4d43293 since it causes higher power consumption for single display use case (4k60). Also, this patch introduced a 35% performance drop in a Vulkan benchmark. * The patch disabled the ODM-combination on most popular monitors, including 4K, 2K and FHD monitors at 60Hz. * ODM-combination can halve the DPP clock to save power, that is the reason why we introduce ODM-combination, and the PM log shows single pipe consumes more power at 4K@60Hz. * ODM-combination has 2 de-tiled buffer involved, which provides longer self-sustained time, that benefit to the memory power optimization.

Zero-length and one-element arrays are deprecated, and we are moving towards adopting C99 flexible-array members, instead.

2023-06-09drm/amdkfd: add debug set flags operationJonathan Kim3-0/+61
Allow the debugger to set single memory and single ALU operations. Some exceptions are imprecise (memory violations, address watch) in the sense that a trap occurs only when the exception interrupt occurs and not at the non-halting faulty instruction. Trap temporaries 0 & 1 save the program counter address, which means that these values will not point to the faulty instruction address but to whenever the interrupt was raised. Setting the Single Memory Operations flag will inject an automatic wait on every memory operation instruction forcing imprecise memory exceptions to become precise at the cost of performance. This setting is not permitted on debug devices that support only a global setting of this option. Return the previous set flags to the debugger as well.

2023-06-09drm/amdkfd: add debug set and clear address watch points operationJonathan Kim13-5/+452
Shader read, write and atomic memory operations can be alerted to the debugger as an address watch exception. Allow the debugger to pass in a watch point to a particular memory address per device. Note that there exists only 4 watch points per devices to date, so have the KFD keep track of what watch points are allocated or not.

2023-06-09drm/amdkfd: add debug suspend and resume process queues operationJonathan Kim11-14/+512
In order to inspect waves from the saved context at any point during a debug session, the debugger must be able to preempt queues to trigger context save by suspending them. On queue suspend, the KFD will copy the context save header information so that the debugger can correctly crawl the appropriate size of the saved context. The debugger must then also be allowed to resume suspended queues. A queue that is newly created cannot be suspended because queue ids are recycled after destruction so the debugger needs to know that this has occurred. Query functions will be later added that will clear a given queue of its new queue status. A queue cannot be destroyed while it is suspended to preserve its saved context during debugger inspection. Have queue destruction block while a queue is suspended and unblocked when it is resumed. Likewise, if a queue is about to be destroyed, it cannot be suspended. Return the number of queues successfully suspended or resumed along with a per queue status array where the upper bits per queue status show that the request was invalid (new/destroyed queue suspend request, missing queue) or an error occurred (HWS in a fatal state so it can't suspend or resume queues).

2023-06-09drm/amdkfd: add debug wave launch override operationJonathan Kim11-2/+351
This operation allows the debugger to override the enabled HW exceptions on the device. On debug devices that only support the debugging of a single process, the HW exceptions are global and set through the SPI_GDBG_TRAP_MASK register. Because they are global, only address watch exceptions are allowed to be enabled. In other words, the debugger must preserve all non-address watch exception states in normal mode operation by barring a full replacement override or a non-address watch override request. For multi-process debugging, all HW exception overrides are per-VMID so all exceptions can be overridden or fully replaced. In order for the debugger to know what is permissible, returned the supported override mask back to the debugger along with the previously enable overrides.

2023-06-09drm/amdkfd: update process interrupt handling for debug eventsJonathan Kim12-19/+686
The debugger must be notified by any debugger subscribed exception that comes from hardware interrupts. If a debugger session exits, any exceptions it subscribed to may still have interrupts in the interrupt ring buffer or KGD/KFD pipeline. To prevent a new session from inheriting stale interrupts, when a new queue is created, open an interrupt drain and allow the IH ring to drain from a timestamped checkpoint. Then inject a custom IV so that once the custom IV is picked up by the KFD, it's safe to close the drain and proceed with queue creation. The drain must also be on debug disable as SW interrupts may still be processed. Drain at this time and clear all the exception status. The debugger may also not be attached nor subscibed to certain exceptions so forward them directly to the runtime. GFX10 also requires its own IV processing, hence the creation of kfd_int_process_v10.c. This is because the IV from SQ interrupts are packed into a new continguous format unlike GFX9. To make this clear, a separate interrupting handling code file was created.
