2008-07-15This is a modified version of Hong's patch from last month, with a fewHong Liu
modifications to make it work correctly on my test hardware (altered the backlight write function, made it enable the legacy backlight controller interrupts on mobile hardware, sorted the interrupt function so we don't get an excessive number of vblank interrupts). This lets the backlight keys on my T61 work properly, though there's a 750msec or so delay between the request and the brightness actually changing - this sounds awfully like the hardware spinning waiting for a status flag to become ready, but as far as I can tell they're all set correctly. If anyone can figure out what's wrong here, it'd be nice to know. Some of the functions are still stubs and just tell the hardware that the request was successful. These can be filled in as kernel modesetting gets integrated. I think it's worth getting this in anyway, since it's required for backlight control to work properly on some new platforms.

2008-06-24i915: register definition & header file cleanupJesse Barnes
It would be nice if one day the DRM driver was the canonical source for register definitions and core macros. To that end, this patch cleans things up quite a bit, removing redundant definitions (some with different names referring to the same register) and generally tidying up the header file.

2008-03-08Switch from PIPE_VBLANK to PIPE_EVENT interrupts.Keith Packard
My 965GM gets interrupts stuck when using the old PIPE_VBLANK interrupt. Switch to the PIPE_EVENT interrupt mechanism, and set the PIPE*STAT registers to use START_VBLANK on 965 and VBLANK on previous chips.

2008-02-16[915]: more registers for S3 (DSPCLK_GATE_D, CACHE_MODE_0, MI_ARB_STATE)Keith Packard
Failing to preserve the MI_ARB_STATE register was causing FIFO underruns on the VGA output on my HP 2510p after resume.

2008-02-07Fix saveGR array sizeJesse Barnes
Make sure we have enough room for all the GR registers or we'll end up clobbering the AR index register (which should actually be harmless unless the BIOS is making an assumption about it).
2008-02-07i915: save/restore interrupt stateJesse Barnes
On resume, if the interrupt state isn't restored correctly, we may end up with a flood of unexpected or ill-timed interrupts, which could cause the kernel to disable the interrupt or vblank events to happen at the wrong time. So save/restore them properly.
2008-02-05i915: Re-report breadcrumbs on poll to the fence manager,Thomas Hellstrom

waiting types. Add a "command_stream_barrier" method to the bo driver.
2008-01-24Remove broken 'in vblank' accountingJesse Barnes
We need to return an accurate vblank count to the callers of ->get_vblank_counter, and in the Intel case the actual frame count register isn't udpated until the next active line is displayed, so we need to return one more than the frame count register if we're currently in a vblank period. However, none of the various ways of doing this is working yet, so disable the logic for now. This may result in a few missed events, but should fix the hangs some people have seen due to the current code tripping the wraparound logic in drm_update_vblank_count.

2008-01-22Correct vblank count valueJesse Barnes
The frame count registers don't increment until the start of the next frame, so make sure we return an incremented count if called during the actual vblank period.

2008-01-03drm: cleanup DRM_DEBUG() parametersMárton Németh
As DRM_DEBUG macro already prints out the __FUNCTION__ string (see drivers/char/drm/drmP.h), it is not worth doing this again. At some other places the ending "\n" was added. airlied:- I cleaned up a few that this patch missed also
2007-12-21Rename inappropriately named 'mask' fields to 'proposed_flags' instead.Keith Packard
Flags pending validation were stored in a misleadingly named field, 'mask'. As 'mask' is already used to indicate pieces of a flags field which are changing, it seems better to use a name reflecting the actual purpose of this field. I chose 'proposed_flags' as they may not actually end up in 'flags', and in an case will be modified when they are moved over. This affects the API, but not ABI of the user-mode interface.

Use clflush on Intel hardware to flush cached objects.
2007-10-29Remove unused memory save areasJesse Barnes
These need to be kmalloc'd separately anyway or we may hit kmalloc size limits.
2007-10-26i915: suspend/resume supportJesse Barnes
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.

of a hardware lock.
2007-10-12i915: add superioctl support to i915Dave Airlie
This adds the initial i915 superioctl interface. The interface should be sufficent even if the implementation may needs fixes/optimisations internally in the drm wrt caching etc.
2007-09-22Add fence error member.Thomas Hellstrom
Modify the TTM backend bind arguments. Export a number of functions needed for driver-specific super-ioctls. Add a function to map buffer objects from the kernel, regardless of where they're currently placed. A number of error fixes.
2007-09-12Remove plane->pipe mapping from SAREA private after allJesse Barnes
We can figure out which pipe a given plane is mapped to by looking at the display control registers instead of tracking it in a new SAREA private field. If this becomes a performance problem, we could move to an ioctl based solution by adding a new parameter for the DDX to set (defaulting to the old behavior if the param was never set of course).
2007-09-11Disambiguate planes & pipes for swap operationsJesse Barnes
This mod makes the SAREA track plane to pipe mappings and corrects the name of the plane info variables (they were mislabeled as pipe info since until now all code assumed a direct mapping between planes and pipes). It also updates the flip ioctl argument to take a set of planes rather than pipes, since planes are flipped while pipes generate vblank events.

2007-08-11i915: i965 non-secure batchbuffer bit has moved.Dave Airlie
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.
