* drm/radeon: don't actually enable the IRQ regs until irq is enabledDave Airlie2008-12-092-5/+4
| | | | | | | vblank can try and enable the IRQ registers before we've set the interrupt handler up. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: move drm vblank initialization/cleanup to driver load/unloadKeith Packard2008-11-252-5/+6
| | | | | | | | | drm vblank initialization keeps track of the changes in driver-supplied frame counts across vt switch and mode setting, but only if you let it by not tearing down the drm vblank structure.

* drm/radeon: map registers at load timeDave Airlie2008-11-112-7/+10
| | | | | | | | | | | | | | | Now that the radeon driver has suspend/resume functions, it needs to map its registers at load time or it will likely crash if a suspend operation occurs before the driver has been initialized. This patch moves the register mapping code from firstopen to load and makes the mapping into a _DRM_DRIVER one so that the core won't remove it at lastclose time. Fixes (at least partially) kernel bz #11891. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@linux.ie>
* drm/radeon: fixup further bus mastering confusion.Alex Deucher2008-10-282-13/+14
| | | | | | rs400/480 are like previous chips not like rs6xx chips. Signed-off-by: Dave Airlie <airlied@redhat.com>
* radeon: fix PCI bus mastering support enables.Alex Deucher2008-10-182-2/+39
| | | | | | | | Someone noticed these registers moved around for later chips, so we redo the codepaths per-chip. PCIE chips don't appear to require explicit enables. Signed-off-by: Dave Airlie <airlied@redhat.com>
* radeon: add RS400 family support.Alex Deucher2008-10-182-2/+5
| | | | | | This adds support for the RS400 family of IGPs for Intel CPUs. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/radeon: add support for RS740 IGP chipsets.Alex Deucher2008-10-182-9/+19
| | | | | | This adds support for the HS2100 IGP chipset. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: kill drm_device->irqJesse Barnes2008-10-181-1/+1
| | | | | | | | | Like the last patch but adds a macro to get at the irq value instead of dereferencing pdev directly. Should make things easier for the BSD guys and if we ever support non-PCI devices. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: Rework vblank-wait handling to allow interrupt reduction.Jesse Barnes2008-10-184-115/+214
| | | | | | | | | | | | | | | Previously, drivers supporting vblank interrupt waits would run the interrupt all the time, or all the time that any 3d client was running, preventing the CPU from sleeping for long when the system was otherwise idle. Now, interrupts are disabled any time that no client is waiting on a vblank event. The new method uses vblank counters on the chipsets when the interrupts are turned off, rather than counting interrupts, so that we can continue to present accurate vblank numbers.

* drm/radeon: downgrade debug message from info to debug.Dave Airlie2008-09-011-2/+2
| | | | | | | | | If this triggers its bad, however some machines seem to have been triggering it for ages and we didn't know until we added the debug. So downgrade the debug now so people don't call this a regression. Signed-off-by: Dave Airlie <airlied@redhat.com>
* Merge branch 'drm-patches' of ↵Linus Torvalds2008-08-274-63/+195
|\ | | | | | | | | | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6 * 'drm-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: drm: don't set the signal blocker on the master process. drm: don't call the vblank tasklet with irqs disabled. r300: Fix cliprect emit drm/radeon: r300_cmdbuf: Always emit INDX_BUFFER immediately after DRAW_INDEX radeon: fix some hard lockups on r3/4/500s
| * r300: Fix cliprect emitNicolai Haehnle2008-08-251-1/+4
| | | | | | | | | | | | | | | | | | | | | | This makes our handling of cliprects sane. drm_clip_rect always has exclusiv bottom-right corners, but the hardware expects inclusive bottom-right corner so we adjust this here. This complements Michel Daenzer's commit 57aea290e1e0a26d1e74df6cff777eb9f03 to Mesa. See also http://bugs.freedesktop.org/show_bug.cgi?id=16123 Signed-off-by: Dave Airlie <airlied@redhat.com>
| * drm/radeon: r300_cmdbuf: Always emit INDX_BUFFER immediately after DRAW_INDEXNicolai Haehnle2008-08-251-16/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DRAW_INDEX writes a vertex count to VAP_VF_CNTL. Docs say that behaviour is undefined (i.e. lockups happen) when this write is not followed by the right number of vertex indices. Thus we used to do the wrong thing when drawing across many cliprects was necessary, because we emitted a sequence DRAW_INDEX, DRAW_INDEX, INDX_BUFFER, INDX_BUFFER instead of DRAW_INDEX, INDX_BUFFER, DRAW_INDEX, INDX_BUFFER The latter is what we're doing now and which ought to be correct.

| * radeon: fix some hard lockups on r3/4/500sJerome Glisse2008-08-254-49/+130
| | | | | | | | | | | | | | | | This patch should fix 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). Signed-off-by: Dave Airlie <airlied@redhat.com>
* | Remove newline from the description of module parametersNiels de Vos2008-08-011-1/+1
|/ | | | | | | | | | | | | | | | | | | | Some module parameters with only one line have the '\n' at the end of the description. This is not needed nor wanted as after the description the type (i.e. int) is followed by a newline. Some modules contain a multi-line description, these are not affected by this patch.

* drm/radeon: fixup issue with radeon and PAT support.Dave Airlie2008-07-151-1/+1

* drm: reorganise drm tree to be more future proof.Dave Airlie2008-07-1411-0/+12251
With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
