771fe6b9 - drm/radeon: introduce kernel modesetting for radeon hardware

Fri, 05 Jun 2009 12:42:42 +0000

drm/radeon: introduce kernel modesetting for radeon hardwareAdd kernel modesetting support to radeon driver, use the ttm memorymanager to manage memory and DRM/GEM to provide userspace API.In order to avoid backward compatibility issue and to allow cleandesign and code the radeon kernel modesetting use different code paththan old radeon/drm driver.When kernel modesetting is enabled the IOCTL of radeon/drmdriver are considered as invalid and an error message is printedin the log and they return failure.KMS enabled userspace will use new API to talk with the radeon/drmdriver. The new API provide functions to create/destroy/share/mmapbuffer object which are then managed by the kernel memory manager(here TTM). In order to submit command to the GPU the userspaceprovide a buffer holding the command stream, along this bufferuserspace have to provide a list of buffer object used by thecommand stream. The kernel radeon driver will then place bufferin GPU accessible memory and will update command stream to reflectthe position of the different buffers.The kernel will also perform security check on command streamprovided by the user, we want to catch and forbid any illegal useof the GPU such as DMA into random system memory or into memorynot owned by the process supplying the command stream. This partof the code is still incomplete and this why we propose that patchas a staging driver addition, future security might forbid currentexperimental userspace to run.This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX(radeon up to X1950). Works is underway to provide support for R6XX,R7XX and newer hardware (radeon from HD2XXX to HD4XXX).Authors: Jerome Glisse Dave Airlie Alex Deucher Signed-off-by: Jerome Glisse Signed-off-by: Dave Airlie Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie List of files: /linux-6.15/drivers/gpu/drm/radeon/ObjectID.h
