The GEM vm operations structure is passed to the VM core that stores it in a const field. There vm operations structures can thus be const in DRM as well. Signed-off-by:

Poulsbo needs a physical address in the cursor base register. We allocate a stolen memory buffer and copy the cursor image provided by userspace into it. When/If we get our own userspace driver we can map this stolen memory directly. The patch also adds a mark in chip ops so we can identify devices that has this requirement. Signed-off-by:

Merge tag 'drm-intel-next-2012-05-20' of git://people.freedesktop.org/~danvet/drm-intel into drm-core-next Daniel wrote: The last pull I'd like to squeeze into 3.5, safe for the hsw stuff mostly bugfixes: - last few patches for basic hsw enabling (Eugeni, infoframe support by Paulo) - Fix up infoframe support, we've hopefully squashed all the cargo-culting in there (Paulo). Among all the issues, this finally fixes some of the infoframe regressions seen on g4x and snb systems. - Fixup sdvo infoframe support, this fixes a regression from 2.6.37. - Correctly enable semaphores on snb, we've enabled it already for 3.5, but the dmar check was slightly wrong. - gen6 irq fixlets from Chris. - disable gmbus on i830, the hw seems to be simply broken. - fix up the pch pll fallout (Chris & me). - for_each_ring macro from Chris - I've figured I'll merge this now to avoid backport pain. - complain when the rps state isn't what we expect (Chris). Note that this is shockingly easy to hit and hence pretty much will cause a regression report. But it only tells us that the gpu turbo state got out of whack, a problem we know off since a long time (it cause the gpu to get stuck a a fixed frequency, usually the lowest one). Chris is working on a fix, but we haven't yet found a magic formula that works perfectly (only patches that massively reduce the frequency of this happening). - MAINTAINERS patch, I'm now officially the guy to beat up." * tag 'drm-intel-next-2012-05-20' of git://people.freedesktop.org/~danvet/drm-intel: (57 commits) drm/i915: IBX has a fixed pch pll to pch pipe mapping drm/i915: implement hsw_write_infoframe drm/i915: small hdmi coding style cleanups drm/i915: fixup infoframe support for sdvo drm/i915: Enable the PCH PLL for all generations after link training drm/i915: Convert BUG_ON(!pll->active) and friends to a WARN drm/i915: don't clobber the pipe param in sanitize_modesetting drm/i915: disable gmbus on i830 drm/i915: Replace the feature tests for BLT/BSD with ring init checks drm/i915: Check whether the ring is initialised prior to dispatch drm/i915: Introduce for_each_ring() macro drm/i915: Assert that the transcoder is indeed off before modifying it drm/i915: hook Haswell devices in place drm/i915: prepare HDMI link for Haswell drm/i915: move HDMI structs to shared location drm/i915: add WR PLL programming table drm/i915: add support for DDI-controlled digital outputs drm/i915: detect digital outputs on Haswell drm/i915: program iCLKIP on Lynx Point drm/i915: program WM_LINETIME on Haswell ...

At least the worst offenders: - SDVO specifies that the encoder should compute the ecc. Testing also shows that we must not send the ecc field, so copy the dip_infoframe struct to a temporay place and avoid the ecc field. This way the avi infoframe is exactly 17 bytes long, which agrees with what the spec mandates as a minimal storage capacity (with the ecc field it would be 18 bytes). - Only 17 when sending the avi infoframe. The SDVO spec explicitly says that sending more data than what the device announces results in undefined behaviour. - Add __attribute__((packed)) to the avi and spd infoframes, for otherwise they're wrongly aligned. Noticed because the avi infoframe ended up being 18 bytes large instead of 17. We haven't noticed this yet because we don't use the uint16_t fields yet (which are the only ones that would be wrongly aligned).

Hidden away within one chipset specific path was the necessary logic to turn on the PLL. This needs to be done everywhere in order for us to drive any display! As such as soon as we tested on a non-CougarPoint chipset, we failed to bring up any DisplayPorts and generated a nice set of assertion failures in the process. At least one part of our logic is working, the part that assumes that we have no idea what we are doing.

Turn a fatal lockup into a merely blank display with lots of shouty messages. v2: Whilst in the area, convert the other BUG_ON into less fatal errors. In particular, note that we may be called on a PCH platform not using PLLs, such as Haswell, and so we do not always want to BUG_ON(!pll) Signed-off-by:

Chris Wilson authored
In many places we wish to iterate over the rings associated with the GPU, so refactor them to use a common macro. Along the way, there are a few code removals that should be side-effect free and some rearrangement which should only have a cosmetic impact, such as error-state. Note that this slightly changes the semantics in the hangcheck code: We now always cycle through all enabled rings instead of short-circuiting the logic. v2: Pull in a couple of suggestions from Ben and Daniel for intel_ring_initialized() and not removing the warning (just moving them to a new home, closer to the error).

On Haswell, we need to properly train the DDI buffers prior to enabling HDMI, and enable the required clocks with correct dividers for the desired frequency. Also, we cannot simple reuse HDMI routines from previous generations of GPU, as most of HDMI-specific stuff is being done via the DDI port programming instead of HDMI-specific registers. This commit take advantage of the WR PLL clock table which is in a separate (previous) commit to select the right divisors for each mode. Signed-off-by:

This table is used for programming WR PLL clocks, used by HDMI and DVI outputs. I split it into a separate patch to simplify the HDMI enabling patch which was getting huge. Note that this table is a temporary solution for WR PLL programming. It will be reworked into a more exact algorithm at a later stage. But for now, it provides the most accurate clock setting solution, so we use it here. Signed-off-by:

Those are driven by DDIs on Haswell architecture, so we need to keep track of which DDI is being used on each output. Reviewed-by:

Eugeni Dodonov authored
Digital port detection on Haswell is indicated by the presence of a bit in DDI_BUF_CTL for port A, and by a different register for ports B, C and D. So we check for those bits during the initialization time and let the hdmi function know about those. Note that this bit does not indicates whether the output is DP or HDMI. However, the DDI buffers can be programmed in a way that is shared between DP/HDMI and FDI/HDMI except for PORT E. So for now, we detect those digital outputs as being HDMI, but proper DP support is still pending. Note that DDI A can only drive eDP, so we do not handle it here for hdmi initialization. v2: simplify Haswell handling logic v3: use generic function for handling digital outputs. Signed-off-by:

The iCLKIP clock is used to drive the VGA pixel clock on the PCH. In order to do so, it must be programmed to properly do the clock ticks according to the divisor, phase direction, phase increments and a special auxiliary divisor for 20MHz clock. v2: calculate divisor values directly instead of relying on a table. v3: merged a fix from Ben to properly check for invalid divider values.

The line time can be programmed according to the number of horizontal pixels vs effective pixel rate ratio. v2: improve comment as per Chris Wilson suggestion v3: incorporate latest changes in specs. v4: move into wm update routine, also mention that the same routine can program IPS watermarks. We do not have their enablement code yet, nor handle the required clock settings at the moment, so this patch won't program those values for now. Signed-off-by:
