2008-06-24[intel] Get vblank pipe from irq_mask_reg instead of hardware enable regKeith Packard
With the interrupt enable/disable using only the mask register, it was wrong to use the enable register to detect which pipes had vblank detection turned on. Also, as we keep a local copy of the mask register around, and MSI machines smack the hardware during the interrupt handler, it is more efficient and more correct to use the local copy.
2008-06-24[intel] Create functions to enable/disable interruptsKeith Packard
This shares common code sequences for managing the interrupt register bits
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] Count received interruptsKeith Packard
Another patch adds this to a /proc/dri file for debugging and monitoring.
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.

2008-06-13[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.
2008-06-13Fix 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.
2008-06-12Don'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.

2008-06-10[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.

2008-05-30modesetting: the great renaming.Dave Airlie
Okay we have crtc, encoder and connectors. No more outputs exposed beyond driver internals I've broken intel tv connector stuff. Really for TV we should have one TV connector, with a sub property for the type of signal been driven over it
2008-05-30modesetting: reorganise out crtc/outputs are allocated.Dave Airlie
Use subclassing from the drivers to allocate the objects. This saves two objects being allocated for each crtc/output and generally makes exit paths cleaner.
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.

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.
2008-05-22[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.
2008-05-13i915: 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.

2008-04-22clear interrupt status before install irqHong Liu
On my 865G machine, it seems the CPU will receive interrupt before irq_postinstall is called. This will cause kernel oops because vblank is not inited at that time. Clear interrupt status before install seems fixing this problem. Signed-off-by: Hong Liu <hong.liu@intel.com>

The batchbuffer submission paths were fixed to use the 965-specific command, but the vblank tasklet was not. When the older version is sent, the 965 will lock up.

My 965GM gets interrupts stuck when using the old PIPE_VBLANK interrupt. Switch to the PIPE_EVENT interrupt mechanism, and set the PIPE*STAT registers to use START_VBLANK on 965 and VBLANK on previous chips.

2008-01-24Remove broken 'in vblank' accountingJesse Barnes
We need to return an accurate vblank count to the callers of ->get_vblank_counter, and in the Intel case the actual frame count register isn't udpated until the next active line is displayed, so we need to return one more than the frame count register if we're currently in a vblank period. However, none of the various ways of doing this is working yet, so disable the logic for now. This may result in a few missed events, but should fix the hangs some people have seen due to the current code tripping the wraparound logic in drm_update_vblank_count.
2008-01-23Fix thinko in get_vblank_counterJesse Barnes
Should use vtotal not htotal to figure out if we're in a vblank period.
2008-01-22Correct vblank count valueJesse Barnes
The frame count registers don't increment until the start of the next frame, so make sure we return an incremented count if called during the actual vblank period.
2008-01-22i915 irq fixesJesse Barnes
Ack the IRQs correctly (PIPExSTAT first followed by IIR). Don't read vblank counter registers on disabled pipes (might hang otherwise). And deal with flipped pipe/plane mappings if present.
