drm/xe: Select CONFIG_DEVICE_PRIVATE when DRM_XE_GPUSVM is selected

2026-01-22T10:27:25+00:00

CONFIG_DEVICE_PRIVATE is a prerequisite for DRM_XE_GPUSVM.
Explicitly select it so that DRM_XE_GPUSVM is not unintentionally
left out from distro configs not explicitly enabling
CONFIG_DEVICE_PRIVATE.

v2:
- Select also CONFIG_ZONE_DEVICE since it's needed by
  CONFIG_DEVICE_PRIVATE.
v3:
- Depend on CONFIG_ZONE_DEVICE rather than selecting it.

drm, drm/xe: Fix xe userptr in the absence of CONFIG_DEVICE_PRIVATE

2026-01-22T09:41:18+00:00

CONFIG_DEVICE_PRIVATE is not selected by default by some distros,
for example Fedora, and that leads to a regression in the xe driver
since userptr support gets compiled out.

It turns out that DRM_GPUSVM, which is needed for xe userptr support
compiles also without CONFIG_DEVICE_PRIVATE, but doesn't compile
without CONFIG_ZONE_DEVICE.
Exclude the drm_pagemap files from compilation with !CONFIG_ZONE_DEVICE,
and remove the CONFIG_DEVICE_PRIVATE dependency from CONFIG_DRM_GPUSVM and
the xe driver's selection of it, re-enabling xe userptr for those configs.

v2:
- Don't compile the drm_pagemap files unless CONFIG_ZONE_DEVICE is set.
- Adjust the drm_pagemap.h header accordingly.

drm/xe/userptr: replace xe_hmm with gpusvm

2025-09-05T10:45:47+00:00

Goal here is cut over to gpusvm and remove xe_hmm, relying instead on
common code. The core facilities we need are get_pages(), unmap_pages()
and free_pages() for a given useptr range, plus a vm level notifier
lock, which is now provided by gpusvm.

v2:
  - Reuse the same SVM vm struct we use for full SVM, that way we can
    use the same lock (Matt B & Himal)
v3:
  - Re-use svm_init/fini for userptr.
v4:
  - Allow building xe without userptr if we are missing DRM_GPUSVM
    config. (Matt B)
  - Always make .read_only match xe_vma_read_only() for the ctx. (Dafna)
v5:
  - Fix missing conversion with CONFIG_DRM_XE_USERPTR_INVAL_INJECT
v6:
  - Convert the new user in xe_vm_madise.

Mark xe driver as BROKEN if kernel page size is not 4kB

2025-08-04T09:24:03+00:00

This driver, for the time being, assumes that the kernel page size is 4kB,
so it fails on loong64 and aarch64 with 16kB pages, and ppc64el with 64kB
pages.

drm/xe: Support for I2C attached MCUs

2025-07-10T14:19:41+00:00

Adding adaption/glue layer where the I2C host adapter
(Synopsys DesignWare I2C adapter) and the I2C clients (the
microcontroller units) are enumerated.

The microcontroller units (MCU) that are attached to the GPU
depend on the OEM. The initially supported MCU will be the
Add-In Management Controller (AMC).

drm/gpusvm, drm/pagemap: Move migration functionality to drm_pagemap

2025-06-26T16:00:07+00:00

The migration functionality and track-keeping of per-pagemap VRAM
mapped to the CPU mm is not per GPU_vm, but rather per pagemap.
This is also reflected by the functions not needing the drm_gpusvm
structures. So move to drm_pagemap.

With this, drm_gpusvm shouldn't really access the page zone-device-data
since its meaning is internal to drm_pagemap. Currently it's used to
reject mapping ranges backed by multiple drm_pagemap allocations.
For now, make the zone-device-data a void pointer.

Alter the interface of drm_gpusvm_migrate_to_devmem() to ensure we don't
pass a gpusvm pointer.

Rename CONFIG_DRM_XE_DEVMEM_MIRROR to CONFIG_DRM_XE_PAGEMAP.

Matt is listed as author of this commit since he wrote most of the code,
and it makes sense to retain his git authorship.
Thomas mostly moved the code around.

v3:
- Kerneldoc fixes (CI)
- Don't update documentation about how the drm_pagemap
  migration should be interpreted until upcoming
  patches where the functionality is implemented.
  (Matt Brost)
v4:
- More kerneldoc fixes around timeslice_ms
  (Himal Ghimiray, Matt Brost)
v6:
- Fix an uninitialized pagemap pointer (CI)
