2008-05-08Clean up whinging from checkpatch.pl in drm_gem.cKeith Packard
Whitespace changes, a few too-long-lines and some extra braces.
2008-05-08GEM: Fix oops on NULL dereference when we try clflushing when we don't need to.Eric Anholt
2008-05-08[intel-gem] Move domains to relocation records. add set_domain ioctl.Keith Packard
Domain information is about buffer relationships, not buffer contents. That means a relocation contains the domain information as it knows how the source buffer references the target buffer. This also adds the set_domain ioctl so that user space can move buffers to the cpu domain.
2008-05-07Apply a few stylistic cleanups to match kernel code.Arjan van de Ven
2008-05-07GEM: Wait for existing rendering to complete before writing relocation data.Eric Anholt
This should already have been generally safe since we don't change contents and put in new relocations between execbufs, so if we were writing in a new relocation then we'd already waited rendering to complete when we moved the target of the relocation. However, doing the right thing will be required if we do buffer reuse.
2008-05-07GEM: Extend cache domain stuff for 965.Eric Anholt
One of our MI_FLUSH bits is reserved on 965, being always implied, and there's a vertex cache that was forgotten.
2008-05-06[intel-GEM] ref count objects in gtt-lru.Keith Packard
If objects on the lru aren't ref counted, they'll get pulled from the gtt as soon as they are freed. This change does cause objects to get stuck in the gtt until they're forced out by new requests. The lru should get cleaned when the irq occurs.
2008-05-06[intel-GEM] Add memory domain support.Keith Packard
Memory domains allow the kernel to track which caches to flush and how to move objects before buffer execution.
2008-05-06Merge commit 'anholt/drm-gem' into drm-gemKeith Packard
2008-05-06Start coding up memory domainsKeith Packard
2008-05-06GEM: Use irq-based fencing rather than syncing and evicting every exec.Eric Anholt
2008-05-06GEM: Skip relocation if presumed offset matches.Eric Anholt
2008-05-06GEM: Save the last ioremapped page for relocations in case we need it again.Eric Anholt
2008-05-05Dump last batch buffer when hardware lockup is detected.Keith Packard
2008-05-05Unlock pages right after getting them.Keith Packard
pages come back from find_or_create_page locked, but must not stay locked for long. Unlock them immediately instead of waiting until we're done with them to avoid deadlock when applications try to touch them.
2008-05-05Merge commit 'anholt/drm-gem' into drm-gemKeith Packard
Conflicts: linux-core/i915_gem.c
2008-05-05GEM: Replace drm_memrange_for_each with just evicting what we brought in.Eric Anholt
I was wrong about how the data structure worked, and didn't care to fix it to support debugging code.
2008-05-05Remove some debug messages.Keith Packard
2008-05-05Add object base to relocation store address.Keith Packard
The relocated value was being written to the wrong location, missing the object base address.
2008-05-05Emit clflush and chipset flush when mapping objects to gttKeith Packard
2008-05-05Correct execbuffer offset. Add memory barrier and chipset flush.Keith Packard
2008-05-05Add i915_dispatch_gem_execbuffer (broken).Keith Packard
This function submits a gem-based execbuffer to the ring. It doesn't work yet.
2008-05-02Don't forget to set the memrange private, and reset ring on kernel entry.Eric Anholt
2008-05-02Don't include the tail guard memrange in foreach callbacking.Eric Anholt
2008-05-02Check for do_mmap errorsKeith Packard
2008-05-02Add a bit of /proc/dri/*/gem support. Clean up some refcount/pagelock issues.Keith Packard
Track named objects in /proc/dri/0/gem_names. Track total object count in /proc/dri/0/gem_objects. Initialize device gem data. return -ENODEV for gem ioctls if the driver doesn't support gem. Call unlock_page when unbinding from gtt. Add numerous misssing calls to drm_gem_object_unreference.
2008-05-02Add name/open ioctls, separate handle and pointer ref counts.Keith Packard
Names are just another unique integer set (from another idr object). Names are removed when the user refernces (handles) are all destroyed -- this required that handles for objects be counted separately from internal kernel references (so that we can tell when the handles are all gone).
2008-05-02Remove drm_driver argument to functions taking drm_gem_object.Keith Packard
Now that drm_gem_object has a drm_driver * in it, functions don't need both parameters.
2008-05-01Add alignment to all aperture allocation requests.Keith Packard
When pinning buffers, or using execbuffer, allow the application to specify the necessary aperture allocation alignment constraints.
2008-05-01Fix gem ioctls to be 32/64-bit clean.Keith Packard
mixed 32/64 bit systems need 'special' help for ioctl where the user-space and kernel-space datatypes differ. Fixing the datatypes to be the same size, and align the same way for both 32 and 64-bit ppc and x86 environments will elimiante the need to have magic 32/64-bit ioctl translation code.
2008-05-01Use krefs for refcounting.Keith Packard
krefs are way easier than a custom-coded spinlock+int combo.
2008-05-01Unbind objects when freeing, fix some error paths, and warn in others.Eric Anholt
2008-05-01Fix offset passed to AGP to be pages instead of bytes.Eric Anholt
Fix some utterly bonged loop while we were staring at it.
2008-05-01Fix missing member settings in obj/obj_priv, and some error paths.Eric Anholt
2008-05-01Make GEM object handles be nonzero.Eric Anholt
2008-05-01Remove _args from gem ioctl argument structure tags.Eric Anholt
2008-05-01Add pin/unpin object ioctls for gem.Eric Anholt
2008-05-01checkpoint: relocations support.Eric Anholt
2008-05-01checkpoint: gtt binding written.Eric Anholt
2008-05-01checkpoint: rename to GEM and a few more i915 bits.Eric Anholt
2008-04-30Hacking towards hooking up execbuffer.Eric Anholt
2008-04-29Remove the remainder of the mmfs device.Eric Anholt
2008-04-29Move mmfs ioctls into the DRM. Untested.Eric Anholt
2008-04-28Rename drm_mm.c and its fuctions to drm_memrange.Eric Anholt
It's not really a graphics memory allocator, just something to track ranges of address space. It doesn't involve actual allocation, and was consuming some desired namespace.
2008-04-23Add mmap ioctl to mmfs.Eric Anholt
2008-04-23Add pread/pwrite ioctls to mmfs.Eric Anholt
2008-04-23Move mmfs.h userland interface to shared-core.Eric Anholt
2008-04-23Initial add of mmfs module.Eric Anholt
2008-04-23Clarify that drm_agp_ttm_backend is associated with a drm_ttm.Eric Anholt
On first looking at it I assumed it was an aspect of the ttm backend as a whole rather than specific allocations from a backend.
2008-04-22linux-core Makefile: add GIT_REVISIONPekka Paalanen
This tries to automatically fetch a git revision string and if succeeds, it #defines GIT_REVISION string macro. Packagers can override it by 'make GIT_REVISION=foo'. Update Nouveau to use GIT_REVISION, if defined, instead of DRIVER_DATE in struct drm_driver. Signed-off-by: Pekka Paalanen <pq@iki.fi>
