[PATCH] intel: Export GT config attributes

From: Jeff McGee Update kernel interface with new I915_GETPARAM ioctl entries for slice total, subslice total, EU total, and threads per EU. Add a wrapping function for each parameter. The motivation for this change is that fusing can be used to create multiple slice, subslice, and EU configurat

[PATCH] intel: Export GT config attributes

From: Jeff McGee The motivation for this change is that fusing can be used to create multiple slice, subslice, and EU configuration within the same PCI ID. CHV is the first such device to do this and thus make an ID-based lookup table approach unreliable. The best solution is for the kernel to de

[PATCH] drm/i915: Export total subslice and EU counts

From: Jeff McGee Setup new I915_GETPARAM ioctl entries for subslice total and EU total. Userspace drivers need these values when constructing GPGPU commands. This kernel query method is intended to replace the PCI ID-based tables that userspace drivers currently maintain. The kernel driver can em

[PATCH] tests/core_getparams: Create new test core_getparams

From: Jeff McGee New test core_getparams consists of 2 subtests, each one testing the ability of userspace to query the correct value of a GT config attribute: subslice total or EU total. drm/i915 implementation of these queries is required for Cherryview and Gen9+ devices (non- simulated). For:

[PATCH 1/2] Add driver callback for updating device info

From: Jeff McGee We need to update some fields of the device's cl_device_id struct at runtime using driver-specific methods. It is best to group all such updates into a single driver callback to avoid opening/initing and deiniting/closing the device multiple times. Signed-off-by: Jeff McGee ---

[PATCH 2/2] Query the driver directly for compute units and subslice

From: Jeff McGee Values of device max compute units and max subslice obtained directly from the driver should be more accurate than our own ID-based lookup values. This is particularly important when a single device ID may encompass more than one configuration. If the driver cannot provide a vali
