2010-07-26drm/nouveau: Reset AGP before running the init scripts.Francisco Jerez
BIOS scripts usually make an attempt to reset the AGP controller, however on some nv4x cards doing it properly involves switching FW off and on: if we do that without updating the AGP bridge settings accordingly (e.g. with the corresponding calls to agp_enable()) we will be locking ourselves out of the card MMIO space. Do it from nouveau_mem_reset_agp() before the init scripts are executed. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-07-26drm/nouveau: Reset CRTC owner to 0 before BIOS init.Francisco Jerez
Fixes suspend+multihead on some boards that also use BIOS scripts for modesetting. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-07-26drm/nouveau: No need to lock/unlock the VGA CRTC regs all the time.Francisco Jerez
Locking only makes sense in the VBIOS parsing code as it's executed before CRTC init. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-07-26drm/nouveau: Add some generic I2C gadget detection code.Francisco Jerez
Clean up and move the external TV encoder detection code to nouveau_i2c.c, it's also going to be useful for external TMDS and DDC detection. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-07-26drm/nv04-nv3x: Implement init-compute-mem.Francisco Jerez
Init-compute-mem was the last piece missing for nv0x-nv3x card cold-booting. This implementation is somewhat lacking but it's been reported to work on most chipsets it was tested in. Let me know if it breaks suspend to RAM for you.

2010-07-26drm/nouveau: Don't pick an interlaced mode as the panel native mode.Francisco Jerez
Rescaling interlaced modes isn't going to work correctly, and even if it did, come on, interlaced flat panels? are you pulling my leg? Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-07-26drm/nv50: fix regression that break LVDS in some placesBen Skeggs
A previous commit started additionally using the SOR link when trying to match the correct output script. However, we never fill in this field for LVDS so we can never match a script at all. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-07-26drm/nouveau: support fetching LVDS EDID from ACPIBen Skeggs
Based on a patch from Matthew Garrett. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Acked-by: Matthew Garrett <mjg@redhat.com>
2010-07-26drm/nouveau: remove quirk to fabricate DVI-A output on DCB 1.5 boardsBen Skeggs
There's a report of this quirk breaking modesetting on at least one board. After discussion with Francisco Jerez, we've decided to remove it: <darktama> it's not worth limiting the quirk to just where we know it can work? i'm happy either way really :) <curro> hmm, don't think so, most if not all DCB15 cards have just one DAC <curro> and with that quirk there's no way to tell if the load comes from the VGA or DVI port Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Acked-by: Francisco Jerez <currojerez@riseup.net>

2010-07-13drm/nouveau: fix pcirom vbios shadow breakage from acpi rom patchBen Skeggs
On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS, which will break some setups. This patch also removes the different ordering of shadow methods for pre-nv50 chipsets. The reason for the different ordering was paranoia, but it should hopefully be OK to try shadowing PRAMIN first. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-07-13drm/nv04: Enable context switching on PFIFO init.Francisco Jerez

2010-07-13drm/nouveau: Disable PROM access on init.Francisco Jerez
On older cards (<nv17) scanout gets blocked when the ROM is being accessed. PROM access usually comes out enabled from suspend, switch it off. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-07-13drm/nouveau: initialise display before enabling interruptsBen Skeggs
In some situations it's possible we can receive a spurious hotplug IRQ before we're ready to handle it, leading to an oops. Calling the display init before enabling interrupts should clear any pending IRQs on the GPU and prevent this from happening. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-07-13drm/nv50: move dp_set_tmds() function to happen in the last display irqBen Skeggs
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>

2010-07-13drm/nouveau: allocate fixed amount of PRAMIN per channel on all chipsetsBen Skeggs

2010-07-13drm/nouveau: remove ability to use external firmwareBen Skeggs
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>

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-07-13drm/nouveau: add instmem flush() hookBen Skeggs
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>

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-07-13drm/nouveau: remove dev_priv->init_state and friendsBen Skeggs
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>

2010-07-13drm/nv50: rewrite display irq handlerBen Skeggs
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>
2010-07-13drm/nv50: send evo "update" command after each disconnectBen Skeggs
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.

2010-07-13drm/nouveau: Workaround broken TV load detection on a "Zotac FX5200".Francisco Jerez
