Add vram frequency sysfs attributes under the below hierarchy; /device/tile#/memory/freq0 |-max_freq |-min_freq v2: Drop "vram" from attribute names (Rodrigo) v3: Add documentation for new sysfs (Riana) Drop prefix from XEHP_PCODE_FREQUENCY_CONFIG (Riana) v4: Create sysfs under tile#/freq0 after removal of physical_memsize attrbute v5: Revert back to creating sysfs under tile#/memory/freq0 Remove definition of GT_FREQUENCY_MULTIPLIER (Rodrigo) v6: Rename attributes to max/min_freq (Anshuman) Fix review comments (Rodrigo) v7: Make documentation more verbose Move sysfs to separate file (Anshuman) v8: Fix platform specific conditions and add kernel doc (Anshuman) Fix typos and remove redundant headers (Riana) v9: Fix typo (Riana) Change function name to include "sysfs" (Lucas) Signed-off-by: Sujaritha Sundaresan Reviewed-by: Anshuman Gupta Link: https://lore.kernel.org/r/20240109110418.2065101-1-sujaritha.sundaresan@intel.com Signed-off-by: Rodrigo Vivi

drm/xe/hwmon: Expose card reactive critical power

2023-12-21T16:42:08+00:00

Expose the card reactive critical (I1) power. I1 is exposed as power1_crit in microwatts (typically for client products) or as curr1_crit in milliamperes (typically for server). v2: Move PCODE_MBOX macro to pcode file (Riana) v3: s/IS_DG2/(gt_to_xe(gt)->info.platform == XE_DG2) v4: Fix review comments (Andi) Acked-by: Rodrigo Vivi Reviewed-by: Riana Tauro Signed-off-by: Badal Nilawar Reviewed-by: Andi Shyti Link: https://lore.kernel.org/r/20230925081842.3566834-3-badal.nilawar@intel.com Signed-off-by: Rodrigo Vivi

drm/xe: Use XE_REG/XE_REG_MCR

2023-12-19T23:32:21+00:00

These should replace the _MMIO() and MCR_REG() from i915, with the goal of being more extensible, allowing to pass the additional fields for struct xe_reg and struct xe_reg_mcr. Replace all uses of _MMIO() and MCR_REG() in xe. Since the RTP, reg-save-restore and WA infra are not ready to use the new type, just undef the macro like was done for the i915 types previously. That conversion will come later. v2: Remove MEDIA_SOFT_SCRATCH_COUNT/MEDIA_SOFT_SCRATCH re-added by mistake (Matt Roper) Reviewed-by: Matt Roper Link: https://lore.kernel.org/r/20230427223256.1432787-8-lucas.demarchi@intel.com Signed-off-by: Lucas De Marchi Signed-off-by: Rodrigo Vivi

drm/xe: Do not spread i915_reg_defs.h include

2023-12-19T23:29:23+00:00

Reduce the use of i915_reg_defs.h so it can be encapsulated in a single place. 1) If it was being included by mistake, remove 2) If it was included for FIELD_GET()/FIELD_PREP()/GENMASK() and the like, just include 3) If it was included to be able to define additional registers, move the registers to the relavant headers (regs/xe_regs.h or regs/xe_gt_regs.h) v2: - Squash commit fixing i915_reg_defs.h include and with the one introducing regs/xe_reg_defs.h - Remove more cases of i915_reg_defs.h being used when all it was needed was linux/bitfield.h (Matt Roper) - Move some registers to the corresponding regs/*.h file (Matt Roper) Signed-off-by: Lucas De Marchi Reviewed-by: Matt Roper Signed-off-by: Rodrigo Vivi [Rodrigo squashed here the removal of the i915 include]

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: Co-developed-by: Matthew Brost Co-developed-by: Matthew Auld Co-developed-by: Matt Roper Co-developed-by: Thomas Hellström Co-developed-by: Francois Dugast Co-developed-by: Lucas De Marchi Co-developed-by: Maarten Lankhorst Co-developed-by: Philippe Lecluse Co-developed-by: Nirmoy Das Co-developed-by: Jani Nikula Co-developed-by: José Roberto de Souza Co-developed-by: Rodrigo Vivi Co-developed-by: Dave Airlie Co-developed-by: Faith Ekstrand Co-developed-by: Daniel Vetter Co-developed-by: Mauro Carvalho Chehab Signed-off-by: Rodrigo Vivi Signed-off-by: Matthew Brost
