2023-06-09drm/amdgpu: add gfx9 hw debug mode enable and disable callsJonathan Kim
Implement the per-device calls to enable or disable HW debug mode for GFX9 prior to GFX9.4.1. GFX9.4.1 and onward will require their own enable/disable sequence as follow on patches. When hardware debug mode setting is requested, waves will inherit these settings in the Shader Processor Input's (SPI) Sequencer Global Block (SQG). This means that the KGD must drain all waves from the SPI into SQG (approximately 96 SPI clock cycles) prior to debug mode setting to ensure that the order of operations that the debugger expects with regards to debug mode setting transaction requests and wave inheritence of that mode is upheld. Also ensure that exception overrides are reset to their original state prior to debug enable or disable.

during suspend path Users have reported that s2idle wasn't working on OEM Phoenix systems, but it was root caused to be because `CONFIG_AMD_PMC` wasn't set in the distribution kernel config.

2023-06-09drm/amdgpu: setup hw debug registers on driver initializationJonathan Kim
Add missing debug trap registers references and initialize all debug registers on boot by clearing the hardware exception overrides and the wave allocation ID index. The debugger requires that TTMPs 6 & 7 save the dispatch ID to map waves onto dispatch during compute context inspection. In order to correctly set this up, set the special reserved CP bit by default whenever the MQD is initailized.

2023-06-09drm/amdkfd: prepare per-process debug enable and disableJonathan Kim
The ROCm debugger will attach to a process to debug by PTRACE and will expect the KFD to prepare a process for the target PID, whether the target PID has opened the KFD device or not. This patch is to explicity handle this requirement. Further HW mode setting and runtime coordination requirements will be handled in following patches. In the case where the target process has not opened the KFD device, a new KFD process must be created for the target PID. The debugger as well as the target process for this case will have not acquired any VMs so handle process restoration to correctly account for this. To coordinate with HSA runtime, the debugger must be aware of the target process' runtime enablement status and will copy the runtime status information into the debugged KFD process for later query. On enablement, the debugger will subscribe to a set of exceptions where each exception events will notify the debugger through a pollable FIFO file descriptor that the debugger provides to the KFD to manage. Finally on process termination of either the debugger or the target, debugging must be disabled if it has not been done so.

2023-06-09drm/amd: Disallow s0ix without BIOS support againMario Limonciello
commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") showed improvements to power consumption over suspend when s0ix wasn't enabled in BIOS and the system didn't support S3. This patch however was misguided because the reason the system didn't support S3 was because SMT was disabled in OEM BIOS setup. This prevented the BIOS from allowing S3. Also allowing GPUs to use the s2idle path actually causes problems if they're invoked on systems that may not support s2idle in the platform firmware. `systemd` has a tendency to try to use `s2idle` if `deep` fails for any reason, which could lead to unexpected flows. The original commit also fixed a problem during resume from suspend to idle without hardware support, but this is no longer necessary with commit ca4751866397 ("drm/amd: Don't allow s0ix on APUs older than Raven") Revert commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") to make it match the expected behavior again.

2023-06-09tools/virtio: use canonical ftrace pathRoss Zwisler
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing A few spots in tools/virtio still refer to this older debugfs path, so let's update them to avoid confusion.
