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
2008-05-05Monitor ACTHD register while polling for idle ring.Keith Packard
When batch buffers are executing, the ring may be stuck for a long time. Monitor the ACTHD pointer which will show if the execution engine is actually hung.
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.
2008-05-05r500: add allowed range for us config/pixsizeDave Airlie
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.
2008-05-02Fix nouveau warning when returning pointers in uint64_t objects.Keith Packard
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
2008-05-01Update mm tests for GEM rename.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
2008-05-02nv50: enable 0x400500 bit 0 after PGRAPH exception alsoBen Skeggs
No solid idea about what these 2 bits do, but nv50 can now survive a few PGRAPH exceptions just as nv40 does :)
2008-05-02nouveau: guard against channels potentially not having a context, fix nv50Ben Skeggs
2008-05-02nouveau: disable all card interrupts when unknown PFIFO IRQ occurs.Ben Skeggs
This is possibly temporary. I can trigger an unending IRQ storm on G8x in some circumstances, and have no idea how to handle that particular PFIFO exception correctly yet.
2008-05-02nouveau: restore original NV_PFIFO_CACHES_REASSIGN value in fifo handlerBen Skeggs
Doesn't fix any issue I've seen, but is a potential issue if a FIFO IRQ occurs during channel creation/takedown.
2008-05-02nouveau: gather nsource in trap_info()Ben Skeggs
The IRQ handling stuff really is a mess.. On the TODO :)
2008-05-02nv50: PGRAPH exception handling completely different from earlier chipsBen Skeggs
2008-05-01nv50: I cave... Add nv84 initial context values.Ben Skeggs
I swore I'd actually do this properly and not go the horrible route we did with nv4x, but I won't get around to it just yet with so many *actually* interesting things to do first.. One day. Since someone already added nv86, why not!
2008-04-30Hacking towards hooking up execbuffer.Eric Anholt
2008-04-29Remove the remainder of the mmfs device.Eric Anholt
2008-04-29Move mmfs tests over to be drm tests.Eric Anholt
2008-04-29Move mmfs ioctls into the DRM. Untested.Eric Anholt
2008-04-29i915: fix off by one in VGA save/restore of AR & CR regsJesse Barnes
Turns out it's important to save/restore AR14 in particular.
2008-04-29nouveau: NV9x cards exist as well.Maarten Maathuis
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.
2008-04-27Use fixed sized types in new ioctlsJesse Barnes
Make both crtc and the command argument 32 bits to avoid any 32-on-64 compat issues.
