2012-04-30drm/nouveau/bios: fix regression on some nv4x boardBen Skeggs1-3/+7
We started using the connector table on nv4x a while back, and this VBIOS has bad connector indices which causes the wrong encoders to get paired with connectors. Add a quirk to fix this... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-04-04Revert "nouveau/bios: Fix tracking of BIOS image data"Linus Torvalds1-3/+1
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 Herrenschmidt1-1/+3
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 Herrenschmidt1-2/+3
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 Skeggs1-119/+156
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>
2012-03-13drm/nouveau/bios: attempt acpi rom fetch before pciromBen Skeggs1-1/+1
There's cards out there with completely messed up PCIROM images that have a perfectly valid signature.. Sigh! Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-12-21drm/nouveau/gpio: reimplement as nouveau_gpio.c, fixing a number of issuesBen Skeggs1-203/+3
- 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 Skeggs1-1/+9
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 Skeggs1-225/+90
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/i2c: do parsing of i2c-related vbios info in nouveau_i2c.cBen Skeggs1-156/+10
Not much point parsing the vbios data into a struct which is only used once to parse the data into another struct, go directly from vbios to nouveau_i2c_chan. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-12-21drm/nouveau/bios: start refactoring dcb routinesBen Skeggs1-121/+149
This primary reason for this was mostly to avoid duplication of some of this stuff by the MXM-SIS parser. However, some other cleanups will also follow this as a result. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-10-27mm: stack based kmap_atomic()Peter Zijlstra1-4/+4
Keep the current interface but ignore the KM_type and use a stack based approach. The advantage is that we get rid of crappy code like: #define __KM_PTE \ (in_nmi() ? KM_NMI_PTE : \ in_irq() ? KM_IRQ_PTE : \ KM_PTE0) and in general can stop worrying about what context we're in and what kmap slots might be appropriate for that. The downside is that FRV kmap_atomic() gets more expensive. For now we use a CPP trick suggested by Andrew: #define kmap_atomic(page, args...) __kmap_atomic(page) to avoid having to touch all kmap_atomic() users in a single patch.
