drm/ttm/tests: depend on UML || COMPILE_TEST

2024-02-26T15:17:02+00:00

At least the device test requires that no other driver using TTM is
loaded. So make those unit tests depend on UML || COMPILE_TEST to
prevent people from trying them on bare metal.

drm/xe: Introduce a new DRM driver for Intel GPUs

2023-12-12T19:05:48+00:00

Xe, is a new driver for Intel GPUs that supports both integrated and
discrete platforms starting with Tiger Lake (first Intel Xe Architecture).

The code is at a stage where it is already functional and has experimental
support for multiple platforms starting from Tiger Lake, with initial
support implemented in Mesa (for Iris and Anv, our OpenGL and Vulkan
drivers), as well as in NEO (for OpenCL and Level0).

The new Xe driver leverages a lot from i915.

As for display, the intent is to share the display code with the i915
driver so that there is maximum reuse there. But it is not added
in this patch.

This initial work is a collaboration of many people and unfortunately
the big squashed patch won't fully honor the proper credits. But let's
get some git quick stats so we can at least try to preserve some of the
credits:

This patch introduces an initial KUnit test suite for GEM objects
backed by shmem buffers.

v3:
- Explicitly cast pointers in the helpers
- Removed unused pointer to parent dev in struct fake_dev
- Test entries reordering in Kconfig and Makefile sent as a separate patch
v2:
- Improved description of test cases
- Cleaner error handling using KUnit actions
- Alphabetical order in Kconfig and Makefile

drm/imagination: Add skeleton PowerVR driver

2023-11-23T08:01:45+00:00

This adds the basic skeleton of the driver. The driver registers
itself with DRM on probe. Ioctl handlers are currently implemented
as stubs.

Changes since v8:
- Corrected license identifiers

Changes since v5:
- Update compatible string & description to match marketing name
- Checkpatch fixes in to/from_pvr_device/file macros

Changes since v3:
- Clarify supported GPU generations in driver description
- Use drm_dev_unplug() when removing device
- Change from_* and to_* functions to macros
- Fix IS_PTR/PTR_ERR confusion in pvr_probe()
- Remove err_out labels in favour of direct returning
- Remove specific am62 compatible match string
- Drop MODULE_FIRMWARE()

drm/gpuvm: allow building as module

2023-09-25T23:58:28+00:00

Currently, the DRM GPUVM does not have any core dependencies preventing
a module build.

Also, new features from subsequent patches require helpers (namely
drm_exec) which can be built as module.

drm: fix up fbdev Kconfig defaults

2023-09-18T08:52:55+00:00

As a result of the recent Kconfig reworks, the default settings for the
framebuffer interfaces changed in unexpected ways:

Configurations that leave CONFIG_FB disabled but use DRM now get
DRM_FBDEV_EMULATION by default. This also turns on the deprecated /dev/fb
device nodes for machines that don't actually want it.

In turn, configurations that previously had DRM_FBDEV_EMULATION enabled
now only get the /dev/fb front-end but not the more useful framebuffer
console, which is not selected any more.

We had previously decided that any combination of the three frontends
(FB_DEVICE, FRAMEBUFFER_CONSOLE and LOGO) should be selectable, but the
new default settings mean that a lot of defconfig files would have to
get adapted.

Change the defaults back to what they were in Linux 6.5:

 - Leave DRM_FBDEV_EMULATION turned off unless CONFIG_FB
   is enabled. Previously this was a hard dependency but now the two are
   independent. However, configurations that enable CONFIG_FB probably
   also want to keep the emulation for DRM, while those without FB
   presumably did that intentionally in the past.

 - Leave FB_DEVICE turned off for FB=n. Following the same
   logic, the deprecated option should not automatically get enabled
   here, most users that had FB turned off in the past do not want it,
   even if they want the console

 - Turn the FRAMEBUFFER_CONSOLE option on if
   DRM_FBDEV_EMULATION is set to avoid having to change defconfig
   files that relied on it being selected unconditionally in the past.
   This also makes sense since both LOGO and FB_DEVICE are now disabled
   by default for builds without CONFIG_FB, but DRM_FBDEV_EMULATION
   would make no sense if all three are disabled.

Fixes: a5ae331edb02b ("drm: Drop select FRAMEBUFFER_CONSOLE for DRM_FBDEV_EMULATION")
Fixes: 701d2054fa317 ("fbdev: Make support for userspace interfaces configurable")
