2023-12-21drm/xe: Invert mask and val in xe_mmio_wait32.Rodrigo Vivi1-1/+1
The order: 'offset, mask, val'; is more common in other drivers and in special in i915, where any dev could copy a sequence and end up with unexpected behavior. Done with coccinelle: @rule1@ expression gt, reg, val, mask, timeout, out, atomic; @@ - xe_mmio_wait32(gt, reg, val, mask, timeout, out, atomic) + xe_mmio_wait32(gt, reg, mask, val, timeout, out, atomic) spatch -sp_file mmio.cocci *.c *.h compat-i915-headers/intel_uncore.h \ --in-place v2: Rebased after changes on xe_guc_mcr usage of xe_mmio_wait32.

2023-12-20drm/xe/mmio: Use struct xe_regLucas De Marchi1-8/+8
Convert all the callers to deal with xe_mmio_*() using struct xe_reg instead of plain u32. In a few places there was also a rename s/reg/reg_val/ when dealing with the value returned so it doesn't get mixed up with the register address.

2023-12-20drm/xe: Only request PCODE_WRITE_MIN_FREQ_TABLE on LLC platformsMatt Roper1-1/+1
PCODE_WRITE_MIN_FREQ_TABLE is only applicable to platforms with an LLC. Change the discrete GPU check to an LLC check instead; this take care of skipping not only the discrete platforms, but also integrated platforms like MTL that do not have an LLC. Fixes MTL dmesg error: xe 0000:00:02.0: [drm] *ERROR* PCODE Mailbox failed: 1 Illegal Command Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://lore.kernel.org/r/20230410183910.2696628-3-matthew.d.roper@intel.com Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2023-12-20drm/xe: Sort includesLucas De Marchi1-5/+4
Sort includes and split them in blocks: 1) .h corresponding to the .c. Example: xe_bb.c should have a "#include "xe_bb.h" first. 2) #include <linux/...> 3) #include <drm/...> 4) local includes 5) i915 includes This is accomplished by running `clang-format --style=file -i --sort-includes drivers/gpu/drm/xe/*.[ch]` and ignoring all the changes after the includes. There are also some manual tweaks to split the blocks. v2: Also sort includes in headers Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
2023-12-12drm/xe/pcode: fix pcode error checkMatthew Auld1-1/+1
On DG2 we are now getting: [ 104.456607] xe 0000:03:00.0: [drm] *ERROR* PCODE timeout, retrying with preemption disabled Looks like we just need to invert the error check for xe_pcode_try_request(), which returns zero on success.

2023-12-12drm/xe: Remove i915_utils dependency from xe_pcode.Rodrigo Vivi1-56/+38
Expand xe_mmio_wait32 to accept atomic and then use that directly when possible, and create own routine to wait for the pcode status. Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com>
2023-12-12drm/xe: Implement a local xe_mmio_wait32Rodrigo Vivi1-0/+7
Then, move the i915_utils.h include to its user. The overall goal is to kill all the usages of the i915_utils stuff. Yes, wait_for also depends on <linux/delay.h>, so they go together to where it is needed. It will be likely needed anyway directly for udelay or usleep_range.

2023-12-12drm/xe: Introduce a new DRM driver for Intel GPUsMatthew Brost1-0/+296
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: Co-developed-by: Matthew Brost <matthew.brost@intel.com> Co-developed-by: Matthew Auld <matthew.auld@intel.com> Co-developed-by: Matt Roper <matthew.d.roper@intel.com> Co-developed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Co-developed-by: Francois Dugast <francois.dugast@intel.com> Co-developed-by: Lucas De Marchi <lucas.demarchi@intel.com> Co-developed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Co-developed-by: Philippe Lecluse <philippe.lecluse@intel.com> Co-developed-by: Nirmoy Das <nirmoy.das@intel.com> Co-developed-by: Jani Nikula <jani.nikula@intel.com> Co-developed-by: José Roberto de Souza <jose.souza@intel.com> Co-developed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Co-developed-by: Dave Airlie <airlied@redhat.com> Co-developed-by: Faith Ekstrand <faith.ekstrand@collabora.com> Co-developed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Co-developed-by: Mauro Carvalho Chehab <mchehab@kernel.org> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com>
