2013-10-09drm: Remove pci_vendor and pci_device from struct drm_deviceVille Syrjälä
We can get the PCI vendor and device IDs via dev->pdev. So we can drop the duplicated information.

2013-04-26drm/nv04/disp: hide all the cruft away in its own little holeBen Skeggs
It'd be pretty awesome if someone would care enough to port this all properly to a class interface, perhaps submitting a command stream to the core via a sw object on PFIFO (emulating how EVO works basically, and also what nvidia have done forever..).. But, this seems unlikely given how old this hardware is now, so, lets just hide it away. There's a heap of other bits and pieces laying around that are still tangled. I'll (re)move them in pieces.

2012-10-03Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linuxLinus Torvalds
Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked." Tons of conflicts mostly due to silly include line changes, but mostly mindless.

2012-10-03drm/nouveau: restructure source tree, split core from drm implementationBen Skeggs
Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this. No code changes here whatsoever, aside from fixing up a couple of include file pathnames. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-04-04Revert "nouveau/bios: Fix tracking of BIOS image data"Linus Torvalds
This reverts commit d06221c0617ab6d0bc41c4980cefdd9c8cc9a1c1. It turns out to trigger the "BUG_ON(!PageCompound(page))" in kfree(), apparently because the code ends up trying to free somethng that was never kmalloced in the first place. BenH points out that the patch was untested and wasn't meant to go into the upstream kernel that quickly in the first place.

2012-04-02nouveau/bios: Fix tracking of BIOS image dataBenjamin Herrenschmidt
The code tries various methods for retreiving the BIOS data. However it doesn't clear the bios->data pointer between the iterations. In some cases, the shadow() method will fail and not update bios->data at all, which will cause us to "score" the old data and incorrectly attribute that score to the new method. This can cause double frees later when disposing of the unused data. Additionally, we were not freeing the data for methods that fail the score test (we only freed when a "best" is superseeded, not when the new method has a lower score than the exising "best"). Fix that as well. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-04-02nouveau: Fix crash when pci_ram_rom() returns a size of 0Benjamin Herrenschmidt
From b15b244d6e6e20964bd4b85306722cb60c3c0809 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt <benh@kernel.crashing.org> Date: Mon, 2 Apr 2012 13:28:18 +1000 Subject: Under some circumstances, pci_map_rom() can return a valid mapping but a size of 0 (if it cannot find an image in the header). This causes nouveau to try to kmalloc() a 0 sized pointer and dereference it, which crashes.

2012-03-13drm/nouveau/bios: rework vbios shadowingBen Skeggs
Refactored to allow shadowing of VBIOS images longer than 64KiB, which allows us to pass the VBIOS checksum test on certain boards. There's also a workaround for reading the PROM VBIOS on some chipsets. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-12-21drm/nouveau/gpio: reimplement as nouveau_gpio.c, fixing a number of issuesBen Skeggs
- moves out of nouveau_bios.c and demagics the logical state definitions - simplifies chipset-specific driver interface - makes most of gpio irq handling common, will use for nv4x hpd later - api extended to allow both direct gpio access, and access using the logical function states - api extended to allow for future use of gpio extender chips - pre-nv50 was handled very badly, the main issue being that all GPIOs were being treated as output-only. - fixes nvd0 so gpio changes actually stick, magic reg needs bashing Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-12-21drm/nouveau/mxm: initial implementation of dcb sanitisationBen Skeggs
The DCB table provided by the VBIOS on most MXM chips has a number of entries which either need to be disabled, or modified according to the MXM-SIS Output Device Descriptors. The x86 vbios code usually takes care of this for us, however, with the large number of laptops now with switchable graphics or optimus, a lot of the time nouveau is responsible for POSTing the card instead - leaving some fun situations like, plugging in a monitor and having nouveau decide 3 connectors actually just got plugged in.. No MXM-SIS fetching methods implemented yet. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-12-21drm/nouveau/disp: parse connector info directly in nouveau_connector.cBen Skeggs
Another case where we parsed vbios data to some structs, then again use that info once to construct another set of data. Skip the intermediate step. This is also slightly improved in that we can now use DCB 3.x connector table info, which will allow NV4x to gain hotplug support, and to make quirks for SPWG LVDS panels unnecessary.

2011-12-21drm/nouveau/bios: start refactoring dcb routinesBen Skeggs
