2012-03-23drm/nouveau/dp: support version 4.0 of DP tableBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/dp: account for channel coding overhead in link trainingBen Skeggs

2012-03-13drm/nvd0/disp: initial implementation of displayportBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/dp: make dp dpms function common, call from sor code insteadBen Skeggs
GF119 will use this too. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/dp: move all nv50/sor-specific code out of nouveau_dp.cBen Skeggs
Off-chip encoders (which we don't support yet anyway), and newer chipsets (such as NVD9...), will need their own code for this. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/dp: make functions for executing various bios tablesBen Skeggs
More code to do the same thing, but will make it easier to handle various changes that could possibly happen the the VBIOS tables. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/dp: fix bad comparison in dp_link_train_commit()Xi Wang
The comparison (lpre == DP_TRAIN_PRE_EMPHASIS_9_5) is always false: lpre is initialized as (lane & 0x0c) >> 2, which is at most 3, while DP_TRAIN_PRE_EMPHASIS_9_5 is defined as (3 << 3). Signed-off-by: Xi Wang <xi.wang@gmail.com> 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/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. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-12-21drm/nouveau/i2c: tidy up bit-bang helpers, also fixing nv50 setsda bugBen Skeggs
Was using nv_mask, which is bad. Reading the reg senses the current line states, which aren't necessarily the states we're trying to drive the lines to. Fixed to store SCL driver state just as we already do for SDA. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-12-21drm/nouveau/bios: pass drm_device to ROMPTR, rather than nvbiosBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: add support for displayport table 0x30Ben Skeggs
Written from observations of my NVD9's vbios, completely untested due to my NVD9 lacking actual DisplayPort connectors.. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: return master dp table pointer too when looking up encoderBen Skeggs
Will need to be able to distinguish 2.0/2.1 from 3.0 soon. Also, move the vbios parsing to nouveau_dp where it belongs. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: preserve non-pattern bits in DP_TRAINING_PATTERN_SETBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: use alternate lane mask for nvafBen Skeggs
Naturally... Because Macs can't just be the same as everything else now can they? Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: link rate scripts are selected with a comparison tableBen Skeggs
Not hardcoded as originally thought. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: enable down-spread if vbios and sink support itBen Skeggs

2011-09-20drm/nouveau/dp: restructure link training codeBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: pass in required datarate to link trainingBen Skeggs
Not used currently, but it will be used in preference to pre-determined lane/bandwidth numbers at a later point. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: remove reliance on vbios for native displayportBen Skeggs

2010-12-03drm/nv50: rework PGPIO IRQ handling and hotplug detectionBen Skeggs
Allows callers to install their own handlers for when a GPIO line changes state (such as for hotplug detect). This also fixes a bug where we weren't acknowledging the GPIO IRQ until after the bottom half had run, causing a severe IRQ storm in some cases.

2010-08-06drm/nv50: use custom i2c algo for dp auxchBen Skeggs
This makes it easier to see how this is working, and lets us transfer the EDID in blocks of 16 bytes. The primary reason for this change is because debug logs are rather hard to read with the hundreds of single-byte auxch transactions that occur. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-04-09drm/nouveau: bail out of auxch transaction if we repeatedly recieve defersBen Skeggs
There's one known case where we never stop recieving DEFER, and loop here forever. Lets not do that.. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-02-09drm/nouveau: make dp auxch xfer len check for reads onlyBen Skeggs
Writes don't return a count, and adding the check broke native DP. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2009-12-16drm/nouveau: use drm debug levelsMaarten Maathuis
- Use driver level (0x2) for NV_DEBUG instead of all levels - Create a NV_DEBUG_KMS for KMS level (0x4) and use them in modesetting code - Remove a few odd NV_TRACE calls and replace some of them with NV_DEBUG_KMS or NV_INFO Signed-off-by: Maarten Maathuis <madman2003@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2009-12-11drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA. This driver is a KMS-based driver and requires a compatible nouveau userspace libdrm and nouveau X.org driver. This driver requires firmware files not available in this kernel tree, interested parties can find them via the nouveau project git archive. This driver is reverse engineered, and is in no way supported by nVidia. Support for nearly the complete range of nvidia hw from nv04->g80 (nv50) is available, and the kms driver should support driving nearly all output types (displayport is under development still) along with supporting suspend/resume. This work is all from the upstream nouveau project found at nouveau.freedesktop.org.
