* drm/nv50: move dp_set_tmds() function to happen in the last display irqBen Skeggs2010-07-131-32/+33
| | | | | | | It seems on some chipsets that doing this from the 0x20 handler causes the display engine to not ever signal the final 0x40 stage. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: allocate fixed amount of PRAMIN per channel on all chipsetsBen Skeggs2010-07-132-44/+50
| | | | | | | | Previously only done on nv50+ This commit also switches unknown NV2x/NV3x chipsets to noaccel mode. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: remove ability to use external firmwareBen Skeggs2010-07-136-244/+49
| | | | | | | This was always really a developer option, and if it's really necessary we can hack this in ourselves. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: add instmem flush() hookBen Skeggs2010-07-1315-152/+39
| | | | | | | | | | This removes the previous prepare_access() and finish_access() hooks, and replaces it with a much simpler flush() hook. All the chipset-specific code before nv50 has its use removed completely, as it's not required there at all. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: remove dev_priv->init_state and friendsBen Skeggs2010-07-137-74/+25
| | | | | | | Nouveau will no longer load at all if card initialisation fails, so all these checks are unnecessary. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nv50: rewrite display irq handlerBen Skeggs2010-07-132-143/+190
| | | | | | | | | The previous handler basically worked correctly for a full-blown mode change. However, it did nothing at all when a partial (encoder only) reconfiguation was necessary, leading to the display hanging on certain types of mode switch. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv50: send evo "update" command after each disconnectBen Skeggs2010-07-133-13/+12
| | | | | | | | | It turns out that the display engine signals an interrupt for disconnects too. In order to make it easier to process the display interrupts correctly, we want to ensure we only get one operation per interrupt sequence - this is what this commit achieves.

* drm/nv04-nv40: Disable connector polling when there're no spare CRTCs left.Francisco Jerez2010-07-133-12/+48
| | | | | | | | | Load detection needs the connector wired to a CRTC, when there are no inactive CRTCs left that means we need to cut some other head off for a while, causing intermittent flickering.

* drm/nv50: supply encoder disable() hook for SOR outputsBen Skeggs2010-07-134-45/+41
| | | | | | | | | | Allows us to remove a driver hack that used to be necessary to disable encoders in certain situations before setting up a mode. The DRM has better knowledge of when this is needed than the driver does. This fixes a number of display switching issues. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv50: DCB quirk for Dell M6300Ben Skeggs2010-07-131-0/+28
| | | | | | | | Uncertain if this is a weirdo configuration, or a BIOS bug. If it's not a BIOS bug, we still don't know how to make it work anyway so ignore a "conflicting" DCB entry to prevent a display hang. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: downgrade severity of most init table parser errorsBen Skeggs2010-07-131-42/+70
| | | | | | | | As long as we know the length of the opcode, we're probably better off trying to parse the remainder of an init table rather than aborting in the middle of it. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: tidy connector/encoder creation a littleBen Skeggs2010-07-1313-83/+84
| | | | | | | | | | | | | | | Create connectors before encoders to avoid having to do another loop across encoder list whenever we create a new connector. This allows us to pass the connector to the encoder creation functions, and avoid using a create_resources() callback since we can now call it directly. This can also potentially modify the connector ordering on nv50. On cards where the DCB connector and encoder tables are in the same order, things will be unchanged. However, there's some cards where the ordering between the tables differ, and in one case, leads us to naming the connectors "wrongly". Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: Don't clear AGPCMD completely on INIT_RESET.Francisco Jerez2010-07-131-1/+2
| | | | | | | | | | | | | We just need to clear the SBA and ENABLE bits to reset the AGP controller: If the AGP bridge was configured to use "fast writes", clearing the FW bit would break the subsequent MMIO writes and eventually end with a lockup. Note that all the BIOSes I've seen do the same as we did (it works for them because they don't use MMIO), OTOH the blob leaves FW untouched.

Eviction becomes a three stage process: 1. Scanning through the lru list until a suitable hole has been found. 2. Scan backwards to restore drm_mm consistency and find out which objects fall into the hole. 3. Evict the objects that fall into the hole. These helper functions don't allocate any memory (at the price of not allowing any other concurrent operations). Hence this can also be used for ttm (which does lru scanning under a spinlock). Evicting objects in this fashion should be more fair than the current approach by i915 (scan the lru for a object large enough to contain the new object). It's also more efficient than the current approach used by ttm (uncoditionally evict objects from the lru until there's enough free space).
