2007-08-13Bug #11895: Only add the AGP base to map offset if the caller didn't.Eric Anholt
The i830 and newer intel 2D code adds the AGP base to map offsets already, because it wasn't doing the AGP enable which used to set dev->agp->base. Credit goes to Zhenyu for finding the issue.

2007-07-21Fix misc ioctl issues, makes Nouveau run.Pekka Paalanen
Debug print fix in drm_release(). Forgotten local variable init in drm_setversion(). Unnecessary put_user() in drm_addmap_ioctl(). ioctl->cmd check broken in drm_ioctl(); workaround.
2007-07-20Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.Eric Anholt
The data is now in kernel space, copied in/out as appropriate according to the This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal with those failures. This also means that XFree86 4.2.0 support for i810 DRM is lost.
2007-07-20Replace filp in ioctl arguments with drm_file *file_priv.Eric Anholt
As a fallout, replace filp storage with file_priv storage for "unique identifier of a client" all over the DRM. There is a 1:1 mapping, so this should be a noop. This could be a minor performance improvement, as everything on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls went the other direction.

2006-12-20Replace vmalloc_32.Thomas Hellstrom
The vmalloc_32 function together with the memset to clear the new pages are replaced with a vmalloc_user. A pre-2.6.18 compat vmalloc_user is added. Please replace any breakage on machines with > 1GB of memory.

Shared memory areas were not cleared when they are allocated and handed to user space. Sensitive information may leak.

2006-12-19drm: ioremap balanced with iounmap for drivers/char/drmDave Airlie

2006-07-11Keep hashed user tokens, with the following changes:Thomas Hellstrom
32-bit physical device addresses are mapped directly to user-tokens. No duplicate maps are allowed, and the addresses are assumed to be outside of the range 0x10000000 through 0x30000000. The user-token is identical to the 32-bit physical start-address of the map. 64-bit physical device addressed are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. Other map types, like upcoming TTM maps are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. This keeps compatibility with buggy drivers, while still implementing a hashed map lookup. The SiS and via device driver major bumps are reverted.
2006-07-10Change drm Map handles to be arbitrary 32-bit hash tokens in the rangeThomas Hellstrom
0x10000000 to 0x90000000 in PAGE_SIZE increments. Implement hashed map lookups. This potentially breaks both 2D and 3D drivers. If so, the corresponding 2D and 3D driver should be fixed, and it's corresponding drm device driver should have its major bumped as soon as possible. Bump sis and via drm device driver majors. The SiS and Unichrome 3D drivers are fixed in Mesa CVS HEAD and mesa_6_4_branch.

2005-11-03Converts the remaining drm_agp_foo functions to be a drm_agp_foo andIan Romanick
drm_agp_foo_ioctl pair. Modifies the MGA DRM to use the drm_agp_foo functions instead of the drm_foo_agp functions. The drm_foo_agp functions are no longer exported by drm.ko. Ensures that dma->seg_count and dma->page_count are properly set in drm_addbufs_{agp,sg,fb}. drm_addbufs_pci was already correct. Ensures that mga_do_agp_dma_bootstrap correctly sets agp_buffer_token. At this point PCI DMA is still broken.

2005-06-28- Remove drm_initmap and replace its usage with drm_addmap. This reducesEric Anholt
code duplication, and it also hands you the map pointer so you don't need to re-find it. - Remove the permanent maps flag. Instead, for register and framebuffer maps, we always check whether there's already a map of that type and offset around. Move the Radeon map initialization into presetup (first open) so it happens again after every takedown. - Remove the split cleanup of maps between driver takedown (last close) and cleanup (module unload). Instead, always tear down maps on takedown, and drivers can recreate them on first open. - Make MGA always use addmap, instead of allocating consistent memory in the PCI case and then faking up a map for it, which accomplished nearly the same thing, in a different order. Note that the maps are exposed to the user again: we may want to expose a flag to avoid this, but it's not a security concern, and saves us a lot of code. - Remove rmmaps in the MGA driver. Since the function is only called during takedown anyway, we can let them die a natural death. - Make removal of maps happen in one function, which is called by both drm_takedown and drm_rmmap_ioctl.
