2008-05-29modesetting: reorganise code into core and helper functions.Dave Airlie
This splits a lot of the core modesetting code out into a file of helper functions, that are only called from themselves and/or the driver. The driver gets called into more often or can call these functions from itself if it is a helper using driver. I've broken framebuffer resize doing this but I didn't like the API for that in any case.

as I'm going to break it.

2008-05-28i915: unmap BIOS when we're done with itJesse Barnes
At the moment, we only read it at startup time, so we can just unmap it there when we're done.

2008-05-27[intel-gem] Replace idlelock usage with real lock acquisition.Eric Anholt
2008-05-26[intel-gem] Must hold DRM lock while setting object domainKeith Packard
Object domain transfer can involve adding flush ops to the request queue, and so the DRM lock must be held to avoid having the X server smash pointers badly.
2008-05-26[i915] leave interrupts masked off when not in use.Keith Packard
The interrupt enable register cannot be used to temporarily disable interrupts, instead use the interrupt mask register. Note that this change means that a pile of buffers will be left stuck on the chip as the final interrupts will not be recognized to come and drain things.
2008-05-25[intel-gem] Add DRM_I915_GEM_BUSY ioctl to check for idle buffers.Keith Packard
This new ioctl returns whether re-using the buffer would force a wait.
2008-05-25[intel-gem] Compute npages instead of nbytes in flush_pwriteKeith Packard
i915_gem_flush_pwrite optimizes short writes to the buffer by clflushing only the modified pages, but it was miscomputing the number of pages.
2008-05-25[intel-gem] replace call to jiffies_to-msec with simple inlineKeith Packard
2008-05-23i915: do a better job of parsing VBIOS dataJesse Barnes
Add code to get panel modes from the VBIOS if present and check whether certain outputs exist. Should make our display detection code a little more robust.
2008-05-23drm_mode_debug_printmodeline doesn't need struct drm_device *Jesse Barnes
Makes printing modelines from some routines easier.
2008-05-22[intel-gem] Encourage multiple caches to hold read dataKeith Packard
When reading from multiple domains, allow each cache to continue to hold data until writes occur somewhere. This is done by first leaving the read_domains alone at bind time (presumably the CPU read cache contains valid data still) and then in set_domain, if no write_domain is specified, the new read domains are simply merged into the existing read domains. A huge comment was added above set_domain to explain how things are expected to work.
2008-05-22[gem] Use CPU domain for new or pageable objectsKeith Packard
Newly allocated objects need to be in the CPU domain as they've just been cleared by the CPU. Also, unmapping objects from the GTT needs to put them into the CPU domain, both to flush rendering as well as to ensure that any paging action gets flushed before we remap to the GTT.
2008-05-22[intel-gem] Force ring retire by emiting flush before user-interrupt.Keith Packard
Commands in the ring are parsed and started when the head pointer passes by them, but they are not necessarily finished until a MI_FLUSH happens. This patch inserts a flush after the execbuffer (the only place a flush wasn't already happening).
2008-05-22[intel-gem] invalidate ring locals for pin/unpin/set_domain/free functionsKeith Packard
Ring locals must be reloaded from hardware in case the X server ran.
2008-05-22[gem] Release GEM buffers from work task scheduled from IRQ.Eric Anholt
There are now 3 lists. Active is buffers currently in the ringbuffer. Flushing is not in the ringbuffer, but needs a flush before unbinding. Inactive is as before. This prevents object_free → unbind → wait_rendering → object_reference and a kernel oops about weird refcounting. This also avoids an synchronous extra flush and wait when freeing a buffer which had a write_domain set (such as a temporary rendered to and then from using the 2d engine). It will sit around on the flushing list until the appropriate flush gets emitted, or we need the GTT space for another operation.
2008-05-22i915: check dummy page before freeingHong Liu
The dummy read page will point to NULL if drm_bo_driver_init failed at firstopen (modeset is not enabled), and will cause kernel oops at subsequent drm_lastclose call, so be sure to check it.
2008-05-21[gem] Replace ring throttling hack with actual time measurement.Eric Anholt
2008-05-21[gem] Fix bad test for list_for_each completion.Eric Anholt
Since it's a circular list, the entry won't be NULL at termination.
2008-05-21[gem] Hold a reference on the object in i915_gem_wait_space.Eric Anholt
Otherwise, in the middle of the function called using it the last ref might disappear.
2008-05-21[intel-gem] invalidate ring locals for pin/unpin/set_domain/free functionsKeith Packard
Ring locals must be reloaded from hardware in case the X server ran.
2008-05-20[gem] Use a separate sequence number field from classic/ttmEric Anholt
This lets us get some qualities we desire, such as using the full 32-bit range (except zero), avoiding DRM_WAIT_ON, and a 1:1 mapping of active sequence numbers to request structs, which will be used soon for throttling and interrupt-driven list cleanup.
2008-05-20[gem] Rename sequence numbers from "cookie" to "seqno"Eric Anholt
2008-05-20[gem] Clean up active/inactive list handling using helper functions.Eric Anholt
Additionally, a boolean active field is added to indicate which list an object is on, rather than smashing last_rendering_cookie to 0 to show inactive. This will help with flush-reduction later on, and makes the code clearer.
2008-05-15[gem] Hold dev->struct_mutex to protect structure data.Eric Anholt
2008-05-15[gem] Rename the GTT LRU lists to active (executing) and inactive (idle).Eric Anholt

2008-05-14Revert "ati_pcigart: fixup properly this version might even work"Dave Airlie
This reverts commit bc0836e12a9790f1cc83f8bc29bc05043c4bc840. tree has some kref hacks in it - oops

2008-05-14ati_pcigart: fill out 40-bit gart table support properlyDave Airlie
Thanks to Alex for supplying this info.
2008-05-13i915: 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.
2008-05-12i915: TV hotplug fixesJesse Barnes
In order to avoid recursive ->detect->interrupt->detect->interrupt->... we need to disable TV hotplug interrupts in intel_tv.c:intel_tv_detect_type. We also need to enable the TV interrupt detection and hotplug sequence properly in i915_irq.c.
2008-05-12[GEM] Typo (and thinking) fixes in drm-gem.txt and doxygen.Eric Anholt
2008-05-12[intel] Minor kludge -- wait for the ring to be nearly empty before queuingKeith Packard
No need to fill the ring that much; wait for it to become nearly empty before adding the execbuffer request. A better fix will involve scheduling ring insertion in the irq handler.
2008-05-12[gem] Set write domain to CPU when doing pwrite.Keith Packard
Leave the flush call in place, which can fix domains up if necessary.
2008-05-12[gem] Clarify use of explicit domain control. Remove Gen3 from I-cache usage.Keith Packard
2008-05-12fix kernel oops when removing fbHong Liu
drm_crtc->fb may point to NULL, f.e X server will allocate a new fb and assign it to the CRTC at startup, when X server exits, it will destroy the allocated fb, making drm_crtc->fb points to NULL.
2008-05-12free dummy read page if fail to init mmHong Liu
Since drm_bo_driver_init will be called in driver_load, we need to free what it alloced when error to avoid memory leak.
2008-05-12drm: remove root only from a lot of drm ioctls to get stuff running as non-rootDave Airlie
2008-05-12drm: masters are always authenticatedDave Airlie
2008-05-12drm: fix oops on reading proc file with no masterDave Airlie
2008-05-11[GEM] Make pread/pwrite manage memory domains. No luck with movnti though.Keith Packard
pread and pwrite must update the memory domains to ensure consistency with the GPU. At some point, it should be possible to avoid clflush through this path, but that isn't working for me.
2008-05-10[intel-GEM] exec list can contain pinned, lru cannot.Keith Packard
The exec list contains all objects, in order of use. The lru list contains only unpinned objects ready to be evicted. This required two changes -- the first was to not migrate pinned objects from exec to lru, the second was to search for the first unpinned object in the exec list when doing eviction.

2008-05-10[GEM] Add drm-gem.txtKeith Packard
Add some API and implementation documentation for GEM.
2008-05-10[intel-GEM] Clean up GEM ioctl naming.Keith Packard
Rename 'validate_entry' to 'exec_object', then clean up some field names in structures (renaming buffer_offset to just offset, for example).
