2023-11-23drm/imagination: Add GPU ID parsing and firmware loadingSarah Walker1-0/+107
Read the GPU ID register at probe time and select the correct features/quirks/enhancements. Use the GPU ID to form the firmware file name and load the firmware. The features/quirks/enhancements arrays are currently hardcoded in the driver for the supported GPUs. We are looking at moving this information to the firmware image. Changes since v8: - Corrected license identifiers Changes since v7: - Fix kerneldoc for pvr_device_info_set_enhancements() Changes since v5: - Add BRN 71242 to device info Changes since v4: - Retrieve device information from firmware header - Pull forward firmware header parsing from FW infrastructure patch - Use devm_add_action_or_reset to release firmware Changes since v3: - Use drm_dev_{enter,exit} Co-developed-by: Frank Binns <frank.binns@imgtec.com> Signed-off-by: Frank Binns <frank.binns@imgtec.com> Co-developed-by: Matt Coster <matt.coster@imgtec.com> Signed-off-by: Matt Coster <matt.coster@imgtec.com> Co-developed-by: Donald Robson <donald.robson@imgtec.com> Signed-off-by: Donald Robson <donald.robson@imgtec.com> Signed-off-by: Sarah Walker <sarah.walker@imgtec.com> Link: https://lore.kernel.org/r/1ff76f7a5b45c742279c78910f8491b8a5e7f6e6.1700668843.git.donald.robson@imgtec.com Signed-off-by: Maxime Ripard <mripard@kernel.org>
2023-11-23drm/imagination: Add skeleton PowerVR driverSarah Walker1-0/+22
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() Co-developed-by: Frank Binns <frank.binns@imgtec.com> Signed-off-by: Frank Binns <frank.binns@imgtec.com> Co-developed-by: Matt Coster <matt.coster@imgtec.com> Signed-off-by: Matt Coster <matt.coster@imgtec.com> Signed-off-by: Sarah Walker <sarah.walker@imgtec.com> Signed-off-by: Donald Robson <donald.robson@imgtec.com> Reviewed-by: Maxime Ripard <mripard@kernel.org> Link: https://lore.kernel.org/r/fed8a77e29620a61aed2684f802339759082cf1b.1700668843.git.donald.robson@imgtec.com Signed-off-by: Maxime Ripard <mripard@kernel.org>
