2008-06-20[intel-gem] Add intel-specific /proc entries to help monitor gem operationKeith Packard
This adds gem_active, gem_flushing, gem_inactive, gem_request and gem_seqno entries to monitor gem operation and help debug issues.
2008-06-20[intel-gem] Use shmem_getpage instead of find_or_create_pageKeith Packard
find_or_create_page doesn't quite set up pages correctly; any newly created pages aren't hooked into the shmem object quite right; user space mmaps of those pages end up mapping pages full of zeros which then get written to the real pages inappropriately. This patch requires that the kernel export shmem_getpage.
2008-06-20[intel-gem] Add DRM_IOCTL_I915_GEM_SW_FINISH to flag CPU writesKeith Packard
When a software fallback has completed, usermode must notify the kernel so that any scanout buffers can be synchronized. This ioctl should be called whenever a fallback completes to flush CPU and chipset caches.

2008-06-16[linux] Use the device's irq for handler setup instead of stale dev->irq.Eric Anholt
This fixes registration when MSI is set up after the stub function fills in dev->irq. Otherwise /proc/interrupts would report attachment to the fasteoi interrupt. dev->irq is still exposed (and updated at IRQ setup) for the drivers that use it for whatever reason.

2008-06-13[intel-gem] throttle based on frames rather than time. Reduces jitter.Keith Packard
Record the last execbuffer sequence for each client. Record that sequence in the throttle ioctl as the 'throttle sequence'. Wait for the last throttle sequence in the throttle ioctl.
2008-06-13[intel] Enable MSI for i915 IRQKeith Packard
2008-06-13[intel] Restructure irq to pend all work until after iir write.Keith Packard
The interrupt identity register must be writen before any work occurs lest we drop an interrupt on the floor. This patch just shuffles code around to make sure that IIR is written as early as possible.
2008-06-13[intel-gem] Use a delayed_work instead of a timer + work_structKeith Packard
We want request retirement to occur about once a second when the request queue is non-empty. This was done with a timer that queued a work_struct, using a delayed_work instead makes a lot more sense.
2008-06-13Fix i915_wait_irq in the presence of interrupt masking.Eric Anholt
In the short-circuit code for the breadcrumb already being new enough, we need to update the sarea_priv copy of the breadcrumb just as if we had waited. Otherwise userland error checking will notice that we returned too early based on its wrong information, and call wait_irq again (leading to spinning until someone else comes along and updates the sarea_priv). This bug was hidden when we had interrupt masking disabled, such as in master, since the interrupt handler would update sarea_priv.
2008-06-13[gem] Remove the interrupt handler for retiring requests.Eric Anholt
This was insufficient once we started masking interrupts to only when someone was waiting for them (and would thus retire requests themselves). It was replaced by the retire_timer.
2008-06-13radeon: bump driver date to know if lockup fix is inJerome Glisse
2008-06-13radeon: r345xx fixe hard lockupJerome Glisse
This patch should fixe hard lockup and convert them in softlockup (ie you can ssh the box but the gpu is busted and we are waiting in loop for it to come back to reason).
2008-06-12Don't clear USER_INTERRUPT if we're not handling it.Eric Anholt
This fixes a regression from commit d434b64f6a760d85295e32298a9a1f3624ee1b69 which could cause us to fail to wake up for user interrupts if we lost a race.
2008-06-11[gem] Another round of cleanups from checkpatch.plEric Anholt
2008-06-11RADEON: use DSTCACHE_CTLSTAT rather than RB2D_DSTCACHE_CTLSTATAlex Deucher
According to the hw guys, you should use DSTCACHE_CTLSTAT to flush the 2D dst cache rather than RB2D_DSTCACHE_CTLSTAT.
2008-06-11[gem] Move potentially device-specific ioctls to the intel driver.Eric Anholt
This is the create (may want location flags), pread/pwrite/mmap (performance tuning hints), and set_domain (will 32 bits be enough for everyone?) ioctls. Left in the generic set are just flink/open/close. The 2D driver must be updated for this change, and API but not ABI is broken for 3D. The driver version is bumped to mark this.
2008-06-10[intel] Fix BUG_ON trigger in irq masking if you did on/off with irqs disabled.Eric Anholt
2008-06-10[gem] Manage the ringbuffer from the kernel in the GEM case.Eric Anholt
This requires that the X Server use the execbuf interface for buffer submission, as it no longer has direct access to the ring. This is therefore a flag day for the gem interface. This also adds enter/leavevt ioctls for use by the X Server. These would get stubbed out in a modesetting implementation, but are required while in an environment where the device's state is only managed by the DRM while X has the VT.

2008-06-09RADEON: Add untested support for RS400 chipsAlex Deucher
GART setup appears to work the same as RS480 chips. Also RC4xx chips are actually RS400 based, not RS480 based.

2008-06-06[intel] remove settable use_mi_batchbuffer_startKeith Packard
The driver can know what hardware requires MI_BATCH_BUFFER vs MI_BATCH_BUFFER_START; there's no reason to let user mode configure this.
2008-06-06[intel-gem] Use timers to retire requests periodically.Keith Packard
Without the user IRQ running constantly, there's no wakeup when the ring empties to go retire requests and free buffers. Use a 1 second timer to make that happen more often.
2008-06-06[intel] free the hardware status page at driver_unloadKeith Packard
This goes with the other hardware status page patch.
2008-06-06[intel-gem] Add explicit throttle ioctlKeith Packard
Instead of throttling and execbuffer time, have the application ask to throttle explicitly. This allows the throttle to happen less often, and without holding the DRM lock.
2008-06-06[intel] Allocate hardware status page at driver load timeKeith Packard
I couldn't get the re-allocated HWS to work on my 965GM, so I just gave up and made it persist across the lifetime of the driver instead.

The i915 driver now works again.
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.
2008-05-22[intel] Add debug code to verify the cached ring tail pointer.Keith Packard
Recording the tail pointer in a local variable improves performance, but if someone messes up and fails to reload at the right time, the driver will write commands to the wrong part of the ring and scramble execution badly. This change (available by setting I915_RING_VALIDATE to 1) checks to make sure the cached tail pointer matches the hardware tail pointer at each ring buffer addition, calling BUG_ON when that's not true.
