2012-11-29drm/nv50/disp: create skeleton display/channel object classesBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nvd0/dmaobj: initial bind() method implementationBen Skeggs
Currently unused, and rudimentary. Lots to figure out here still, but this is sufficient for what disp will need. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nvc0/dmaobj: implement initial bind() methodBen Skeggs
Currently unused. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nv50/dmaobj: extend class to allow gpu-specific attributes to be definedBen Skeggs
disp is going to need to be able to create more specific dma objects than was previously possible. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nvd0/dmaobj: duplicate fermi class, will diverge real soon nowBen Skeggs
The hardware dmaobj format completely changed in GF119, so these will need a separate implementation. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nvc0/dmaobj: stub bind function for now so we can call unconditionallyBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nouveau/dmaobj: move parent class check to bind() methodBen Skeggs
Otherwise when nvc0- gains a bind() method (disp needs it), the fifo engine will attempt to create a dma object for the push buffer, which is unnecessary on fermi. The only sane place to put these checks is in the bind method itself, and have it unconditionally called from wherever it might be needed. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nouveau/dmaobj: merge everything except ctor and bind togetherBen Skeggs
Simplifies things a little, and currently no reason to need chipset-specific dmaobj constructors. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nouveau: pass address to object accessor functions as u64Ben Skeggs
Will be required by future work. Make the API change now to catch any (but hopefully none) unexpected fallout. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nouveau/gpio: place upper limit on using old-school tvdac bios dataBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nouveau: remove newline-only NV_DEBUG callsBen Skeggs
This used to output the function name, now doesn't, so just looks stupid. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-11-29drm/nv40/fb: use an actual compressed zeta formatBen Skeggs
SPLIT is apparently just that, and only splits Z and S components. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-11-29drm/nouveau/fb: create tag heap from common code for all relevant chipsetsBen Skeggs
A nv2x bug wrt hardcoded tag counts is now also fixed as a side-effect. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-11-29drm/nouveau/fb: read TILE_BASE after writing it to avoid a hardware raceBen Skeggs
Apparently needed for turbocache nv4x chips at least, we'll just do it everywhere... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nv40/fb: start bashing zcomp registers on relevant chipsetsBen Skeggs
Always bashing "disabled" for now, actual compressing coming up... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-11-29drm/nv40/fb: split implementation into nv40/nv41/nv44/nv46/nv47/nv49/nv4e piecesBen Skeggs
Wow, this is a nice complicated mess of build-your-own-mc blocks... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-11-29drm/nv20/fb: split implementation into nv20/nv25 piecesBen Skeggs
There's more stuff that can be shared in the constructor, will be merged together again later. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nouveau/fb: split tile and compression region handlingBen Skeggs
This is in preparation for extending the support to the remaining chipsets, to allow for sharing more functions. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-29drm/nouveau/bios: attempt to fetch entire acpi rom image in one shotBen Skeggs
v2: fdo#55948 - the _ROM method silently truncates size to 4KiB, perform a checksum test and fall back to slow _ROM access on failure. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-11-28drm/doc: add new dp helpers into drm DocBookDaniel Vetter
I didn't bother with documenting the really trivial new "extract something from dpcd" helpers, but the i2c over aux ch is now documented a bit. v2: Clarify the comment for i2c_dp_aux_add_bus a bit. v3: Fix more spelling fail spotted by Laurent Pinchart.

2012-11-28drm/doc: integrate fb helper reference into docsDaniel Vetter
Again only minimal changes to make kerneldoc no longer shout. Plus a little introduction in the form of a inline DOC: section to quickly explain what this is all about. v2: Fixup spelling fail.

2012-11-28drm/doc: integrate crtc helper api into docbookDaniel Vetter
- Add the missing doc for drm_helper_move_panel_connectors_to_head. - Fixup any outdated stuff in existing sections. I've only looked at those kerneldoc headers that actually resulted in a complaint from the kerneldoc parser tool. v2: - Actually include the docbook snippet in the right patch. - Fix spelling fail. v3: It's now called drm_crtc_helper_set_mode, spotted by Laurent Pinchart.

2012-11-28drm/doc: Helpers are not a Midlayer!Daniel Vetter
I'm devoting all my wrath to that fight, so don't misname it ;-) v2: Make it clear that this section talks about kms helpers. Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
2012-11-28drm/edid: tune down debug message in parse_hdmi_vsdbDaniel Vetter
Those tend to be totally not interesting for end-users, and for debugging we tend to dump the entire noise anyway by enabling all debug messages.

2012-11-28drm: only build ati_pcigart if PCI enabledJames Hogan
Prevent ati_pcigart.c being built unless PCI is enabled. The exported functions in this file are only used by drivers which depend on PCI (namely r128 and radeon), and it tries to use PCI specific functions (pci_unmap_page, pci_map_page, and pci_dma_mapping_error) that cause compiler errors when PCI is disabled.

2012-11-28drm: tegra: Use framebuffer pitch as line strideThierry Reding
Instead of using the stride derived from the display mode, use the pitch associated with the currently active framebuffer. This fixes a bug where the LCD display content would be skewed when enabling HDMI with a video mode different from that of the LCD.
