2008-06-23[intel] allow the irq code to use either enable or mask registersKeith Packard
still not sure which works best on which hardware; this will make it easier to experiment.
2008-06-23nv50: oops, keep VRAM allocations aligned at 64KiB - that's our page size..Ben Skeggs
2008-06-23nv50: use same dma object for fb/tt accessBen Skeggs
We depend on the VM fully now for memory protection, separate DMA objects for VRAM and GART are unneccesary. However, until the next interface break (soon) a client can't depend on the objects being the same and must still call NV_OBJ_SET_DMA_* methods appropriately.
2008-06-23nouveau: allocate drm-use vram buffers from end of vram.Ben Skeggs
This avoids seeing garbage from engine setup etc before X gets around to pointing the CRTCs at a new scanout buffer. Not actually a noticable problem before G80 as PRAMIN is forced to the end of VRAM by the hardware already.

2008-06-21[intel] Use IMR instead of IER to pend interrupts during ISRKeith Packard
Noting that the interrupt mask register was more reliable than the interrupt enable register for managing interrupts in user_irq_on/user_irq_off, this patch replaces the remaining IER frobbing with IMR instead. The test which exposes IER related failures is: $ glxgears & glxgears & glxgears (reposition the glxgears windows away from the upper left corner) $ while :; do x11perf -rect100 -reps 800 -repeat 1; sleep 1; done & $ while :; do runoa; runet; done &
2008-06-21[intel-gem] Add /proc/dri/*/i915_gem_interruptKeith Packard
This tracks most of the interrupt-related status, including the interrupt registers in the chip and the sequence number variables.
2008-06-21[intel] Count received interruptsKeith Packard
Another patch adds this to a /proc/dri file for debugging and monitoring.
2008-06-21[intel-gem] Remove unused variable.Keith Packard
2008-06-20[intel-gem] Use polling in i915_gem_idle instead of interrupts.Keith Packard
While waiting for the hardware to idle on leavevt or lastclose, poll for the sync sequence number instead of waiting for an interrupt. This allows the code to bail if the hardware hangs for some reason. Also, this avoids issues with signals as the exisiting wait function is interruptible.
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.
2008-06-20Add device-specific proc_init and proc_cleanup hooksKeith Packard
This allows device drivers to add proc files
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.
2008-06-20drm: only use kernel ioctl cmd when doing a core ioctl.Dave Airlie
Need to overhaul the mess that is driver ioctls
2008-06-20r300: fix warningDave Airlie
2008-06-20drm: fix the ioctl to not believe userspace.Dave Airlie
believing userspace causes oopses

2008-06-16[intel] Quirk away MSI support on 945G/GM.Eric Anholt
The PCI caps register reports MSI support even though it isn't really there.
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.
2008-06-15radeon: *really* fix screen corruption thanks to Lukasz KrotowskiJerome Glisse

2008-06-13[intel-gem] Execute MI_FLUSH in leavevt_ioctlKeith Packard
In leavevt_ioctl, queue an MI_FLUSH and then block waiting for it to complete. This will empty the active and flushing lists. That leaves only the inactive list to evict.
2008-06-13[intel-gem] inactive list may contain objects in CPU write domainKeith Packard
Pin/unpin need to know whether to remove/add objects from the inactive list, inactive objects cannot be in any GPU write domain as those would be on the flushing list instead. However, inactive objects may be in the CPU write domain.
2008-06-13[intel-gem] BUG_ON active objects in gem_object_unbindKeith Packard
Now that gem_object_unbind waits for rendering to complete, objects should not be active when they are being pulled from the GTT. BUG_ON if this is broken.
2008-06-13[intel-gem] Debugging -- verify inactive list invariantsKeith Packard
Inactive list elements may not be pinned, active or have non-CPU write domains.
2008-06-13[intel-gem] whitespace fixesKeith Packard
2008-06-13[intel-gem] show total GTT space in /proc/dri/*/gem_objectsKeith Packard
2008-06-13[intel-gem] Wait for rendering to complete before unbinding.Keith Packard
Moving to the CPU domain doesn't ensure that rendering is finished, the buffer may still be in use as a texture or other data source.
2008-06-13[libdrm] Restart all ioctls on signal receiptKeith Packard
Receiving a signal should be ignored by the library, so just restart any ioctl which returns EINTR or EAGAIN.
2008-06-13[intel-gem] add gtt and pin counts to /proc/dri/*/gem_objectsKeith Packard
Not quite portable, but these are useful for intel. Some more general mechanism could be done...
2008-06-13[intel-gem] Left the last exec buffer pinned. oops.Keith Packard
Loop end variable 'pinned' was set one too low.

2008-06-13[intel-gem] Pin objects during execbufferKeith Packard
Pinning the objects avoids accidentally evicting them while binding other objects.
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-gem] evict_something was failing when wait_request freed objectsKeith Packard
When i915_wait_request clears object from the active list, it may end up freeing them and not moving them to the inactive list. This ends up unbinding objects from the GTT without there ever being new objects visible to i915_gem_evict_something on the inactive list. As the only success condition required the presence of objects on the inactive list, this would falsely assume that no GTT space had been made available, and end up returning -ENOMEM to the application.
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.
2008-06-13[intel-gem] Reorder i915_add_request to schedule work lastKeith Packard
i915_add_request was calling schedule_delayed_work before adding the request to the list; it makes more sense to do that last.
2008-06-13Use /bin/pwd instead of trusting shell built-inKeith Packard
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] Catch -EINTR from blocking ioctls and restart them.Eric Anholt
Thanks to Thomas Hellstrom for catching the issue, no thanks to the kernel developer who authoritatively told me that they would get restarted on their own.
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.
2008-06-13[gem] Don't require the lock in execbuf now that it's not needed for the ring.Eric Anholt
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).
2008-06-12xgi: Bump kernel versionIan Romanick
This should have been bumped when the fence interface was changed the other day. Better late than never, I suppose.
