Giving the opportunity to userspace to associate a free-form name with a drm_file struct is helpful for tracking and debugging. This is similar to the existing DMA_BUF_SET_NAME ioctl. Access to client_name is protected by a mutex, and the 'clients' debugfs file has been updated to print it. Userspace MR to use this ioctl: virgl/virglrenderer!1428 If the string passed by userspace contains chars that would mess up output when it's going to be printed (in dmesg, fdinfo, etc), -EINVAL is returned. A 0-length string is a valid use, and clears the existing name. Reviewed-by:

This happens when a user changes the external monitor when the system is suspended and the embedded controller doesn't not wake AP up.

This commit introduces a DRM device sysfs attribute that lets UM control the job accounting status in the device. The knob variable had been brought in as part of a previous commit, but now we're able to fix it manually. As sysfs files are part of a driver's uAPI, describe its legitimate input values and output format in a documentation file. Signed-off-by:

Drawing from the FW-calculated values in a previous commit, we can increase the numbers for an open file by collecting them from finished jobs when updating their group synchronisation objects.

Enable calculations of job submission times in clock cycles and wall time. This is done by expanding the boilerplate command stream when running a job to include instructions that compute said times right before and after a user CS. A separate kernel BO is created per queue to store those values. Jobs can access their sampled data through an index different from that of the queue's ringbuffer. The reason for this is saving memory on the profiling information kernel BO, since the amount of simultaneous profiled jobs we can write into the queue's ringbuffer might be much smaller than for regular jobs, as the former take more CSF instructions. This commit is done in preparation for enabling DRM fdinfo support in the Panthor driver, which depends on the numbers calculated herein. A profile mode mask has been added that will in a future commit allow UM to toggle performance metric sampling behaviour, which is disabled by default to save power. When a ringbuffer CS is constructed, timestamp and cycling sampling instructions are added depending on the enabled flags in the profiling mask. A helper was provided that calculates the number of instructions for a given set of enablement mask, and these are passed as the number of credits when initialising a DRM scheduler job.

Maybe we could instead have made the call sites conditional, since the callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak fallback. I'll leave that to the kvm people to argue about, this at least gets the build going for that particular config.
