Preempt fences can sleep waiting for an exec queue suspend operation to complete. If the system_unbound_wq is used for waiting and the number of waiters exceeds max_active this will result in other users of the system_unbound_wq getting starved. Use a device private work queue for preempt fences to avoid starvation of the system_unbound_wq. Even though suspend operations can complete out-of-order, all suspend operations within a VM need to complete before the preempt rebind worker can start. With that, use a device private ordered wq for preempt fence waiting. v2: - Add comment about cleanup on failure (Matt R) - Update commit message (Lucas) Fixes: dd08ebf6 ("drm/xe: Introduce a new DRM driver for Intel GPUs") Signed-off-by:

The flags stored in the BO grew over time without following much a naming pattern. First of all, get rid of the _BIT suffix that was banned from everywhere else due to the guideline in drivers/gpu/drm/i915/i915_reg.h that xe kind of follows: Define bits using ``REG_BIT(N)``. Do **not** add ``_BIT`` suffix to the name. Here the flags aren't for a register, but it's good practice to keep it consistent. Second divergence on names is the use or not of "CREATE". This is because most of the flags are passed to xe_bo_create*() family of functions, changing its behavior. However, since the flags are also stored in the bo itself and checked elsewhere in the code, it seems better to just omit the CREATE part. With those 2 guidelines, all the flags are given the form XE_BO_FLAG_<FLAG_NAME> with the following commands: git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i \ -e "s/XE_BO_\([_A-Z0-9]*\)_BIT/XE_BO_\1/g" \ -e 's/XE_BO_CREATE_/XE_BO_FLAG_/g' git grep -le "XE_BO_" -- drivers/gpu/drm/xe | xargs sed -i -r \ -e 's/XE_BO_(DEFER_BACKING|SCANOUT|FIXED_PLACEMENT|PAGETABLE|NEEDS_CPU_ACCESS|NEEDS_UC|INTERNAL_TEST|INTERNAL_64K|GGTT_INVALIDATE)/XE_BO_FLAG_\1/g' And then the defines in drivers/gpu/drm/xe/xe_bo.h are adjusted to follow the coding style.

It's quite redundant to pass XE_BO_CREATE_USER_BIT to xe_bo_create_user() since the only difference of that function is to force that flag. Stop passing the flag in the few cases that were explicitly doing so. Reviewed-by:

Add infra to support card power and energy attributes through channel 0. Package attributes will be now exposed through channel 1 rather than channel 0 as shown below. Channel 0 i.e power1/energy1_xxx used for card and channel 1 i.e power2/energy2_xxx used for package power,energy attributes. power1/curr1_crit and in0_input are moved to channel 1, i.e. power2/curr2_crit and in1_input as these are available for package only. This would be needed for future platforms where they might be separate registers for package and card power and energy. Each discrete GPU supported by Xe driver, would have a directory in /sys/class/hwmon/ with multiple channels under it. Each channel would have attributes for power, energy etc. Ex: /sys/class/hwmon/hwmon2/power1_max /power1_label /energy1_input /energy1_label Attributes will have a label to get more description of it. Labelling is as below. power1_label/energy1_label - "card", power2_label/energy2_label - "pkg". v2: Fix checkpatch errors. v3: - Update intel-xe-hwmon documentation.

We are abusing struct drm_info_list.data by storing there pointer to the xe_gt, while it shouldn't be used for any device specific data. Use recently introduced xe_gt_debugfs_simple_show() that hides all details how to obtain the xe_gt pointer. This will also remove the need for making copies of the struct drm_info_list to get GT specific definitions. Reviewed-by:

Many of our debugfs files are GT specific and require a pointer to struct xe_gt to correctly show its content. Our initial approach to use drm_info_list.data field to pass pointer not only requires extra steps (like copying template per each GT) but also abuses the rule that this data field should not be device specific. Introduce helper function that will use xe_gt pointer stored at parent directory level and use .data only to pass actual print function that would expects xe_gt pointer as a parameter. Reviewed-by:

For each rebind we insert a GuC TLB invalidation and add a corresponding unordered TLB invalidation fence. This might add a huge number of TLB invalidation fences to wait for so rather than doing that, defer the TLB invalidation to the next ring ops for each affected exec queue. Since the TLB is invalidated on exec_queue switch, we need to invalidate once for each affected exec_queue. v2: - Simplify if-statements around the tlb_flush_seqno.

While we are already managing GuC IDs directly in GuC submission code, using bitmap() for MLRC and ida() for SLRC, this code can't be easily extended to meet additional requirements for SR-IOV use cases, like limited number of IDs available on VFs, or ID range reservation for provisioning VFs by the PF. Add a separate component for managing GuC IDs, that will replace existing ID management. Start with bitmap() based implementation that could be optimized later based on perf data.
