* drm: fd.o bug #11895: Only add the AGP base to map offset if the caller didn't.Eric Anholt2008-02-07
| | | | | | | | | 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. Signed-off-by: Dave Airlie <airlied@linux.ie>
* i915: add suspend/resume supportJesse Barnes2008-02-07
| | | | | | | | | Add suspend/resume support to the i915 driver. Moves some of the initialization into the driver load routine, and fixes up places where we assumed no dev_private existed in some of the cleanup paths. This allows us to suspend/resume properly even if X isn't running. Signed-off-by: Dave Airlie <airlied@linux.ie>

* Use helpers to obtain task pid in printksPavel Emelyanov2007-10-19
| | | | | | | | | | | | | | | | The task_struct->pid member is going to be deprecated, so start using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in the kernel. The first thing to start with is the pid, printed to dmesg - in this case we may safely use task_pid_nr(). Besides, printks produce more (much more) than a half of all the explicit pid usage.

* drm: Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.Eric Anholt2007-10-14
| | | | | | | | | The data is now in kernel space, copied in/out as appropriate according to t 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 DR is lost. Signed-off-by: Dave Airlie <airlied@linux.ie>
* drm: Replace filp in ioctl arguments with drm_file *file_priv.Eric Anholt2007-10-14
| | | | | | | | | | 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 everyth on Linux dereferenced filp to get file_priv anyway, while only the mmap ioct went the other direction.

* drm: update user token hashing and map handlesThomas Hellstrom2006-09-21
| | | | | | | | | | | | | | | | | | | Keep hashed user tokens, with the following changes: 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. Implement hashed map lookups. Signed-off-by: Dave Airlie <airlied@linux.ie>
