Once we've read the rates from the sink we don't have to mess with them, so the caller can just look at the stored rates without doing extra copies. If the sink doesn't support the new link rate stuff, we just point the caller at the default_rates[] array. Signed-off-by:

GGTT views are only applicable when dealing with GGTT. Change the code to reject ggtt_view where it should not be used and require it when it should be. v2: - Dropped _ppgtt_ infixes, allow both types to be passed - Disregard other but normal views when no view is specified - More checks that valid parameters are passed - More readable error checking v3: - Prefer WARN_ONCE over BUG_ON when there is code path for failure Signed-off-by:

We don't want to end up in a state where we track that the pipe has its primary plane enabled when primary plane registers are programmed with values that look possible but the plane actually disabled. Refuse to read out the fb state when the primary plane isn't enabled. Suggested-by:

vmap_batch() calculates amount of needed pages for the mapping we are going to create. And it uses this page count as an argument for the for_each_sg_pages() macro. The macro takes the number of sg list entities as an argument, not the page count. So we ended up iterating through all the pages on the mapped object, corrupting memory past the smaller pages[] array. Fix this by bailing out when we have enough pages.

Setup new I915_GETPARAM ioctl entries for subslice total and EU total. Userspace drivers need these values when constructing GPGPU commands. This kernel query method is intended to replace the PCI ID-based tables that userspace drivers currently maintain. The kernel driver can employ fuse register reads as needed to ensure the most accurate determination of GT config attributes. This first became important with Cherryview in which the config could differ between devices with the same PCI ID. The kernel detection of these values is device-specific and not included in this patch. Because zero is not a valid value for any of these parameters, a value of zero is interpreted as unknown for the device. Userspace drivers should continue to maintain ID-based tables for older devices not supported by the new query method. v2: Increment our I915_GETPARAM indices to fit after REVISION which was merged ahead of us.

We accidentally pass 'pipe' instead of 'port' to CHV_PLL_DW8() and with PIPE_C we end up at register offset 0x8320 which isn't the 0x8020 we wanted. Fix it.

Ignore the current state of the pipe and just check crtc_state->enable and the number of FDI lanes required. This means we don't accidentally mistake the FDI lanes as being available of one of the pipes just happens to be disabled at the time of the check. Also we no longer consider pipe C to require FDI lanes when it's driving the eDP transcoder. We also take the opportunity to make the code a bit nicer looking by hiding the ugly bits in the new pipe_required_fdi_lanes() function.

Remove the global modeset resource function that would disable the bifurcation bit, and instead enable/disable it when enabling the pch transcoder. The mode set consistency check should prevent us from disabling the bit if pipe C is enabled so the change should be safe. Note that this doens't affect the logic that prevents the bit being set while a pipe is active, since the patch retains the behavior of only chaging the bit if necessary. Because of the checks during mode set, the first change would necessarily happen with both pipes B and C disabled, and any subsequent write would be skipped. v2: Only change the bit during pch trancoder enable.

On SKL, GT frequency is programmed in units of 16.66 MHZ units compared to 50 MHZ for older platforms. Also the time value specified for Up/Down EI & Up/Down thresholds are expressed in units of 1.33 us, compared to 1.28 us for older platforms. So updated the gen9_enable_rps function as per that. v2: Updated to use new macro GT_INTERVAL_FROM_US v3: Removed the initial setup of certain registers, from gen9_enable_rps, which gets overridden later from gen6_set_rps (Damien) v4: Removed the enabling of rps interrupts, from gen9_enable_rps.

On SKL the frequency is specified in units of 16.66 MHZ, barring the RP_STATE_CAP(0x5998) register, which still reports frequency in units of 50 MHZ.

Wrap the FW register value shift+mask operations into a macro to hide the ugliness a bit. Also might avoid bugs due to typos. Also rename all the primary/sprite plane low order bit masks to have the _VLV suffix, so that we can use the FW_WM_VLV() macro instead of the FW_WM() macro for them in a consistent manner. Cursor and all the high order bits are left to use the FW_WM() macro as there's no real confusion with them. Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by:

Current ILK-style watermark code assumes the primary plane and cursor plane are always enabled. This assumption, along with the combination of two independent commits that got merged at the same time, results in a NULL dereference. The offending commits are: commit fd2d61341bf39d1054256c07d6eddd624ebc4241 Author: Matt Roper <matthew.d.roper@intel.com> Date: Fri Feb 27 10:12:01 2015 -0800 drm/i915: Use plane->state->fb in watermark code (v2) and commit 0fda6568 Author: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Date: Fri Feb 27 15:12:35 2015 +0000 drm/i915/skl: Update watermarks for Y tiling The first commit causes us to use the FB from plane->state->fb rather than the legacy plane->fb, which is updated a bit later in the process. The second commit includes a change that now triggers watermark reprogramming on primary plane enable/disable where we didn't have one before (which wasn't really correct, but we had been getting lucky because we always calculated as if the primary plane was on). Together, these two commits cause the watermark calculation to (properly) see plane->state->fb = NULL when we're in the process of disabling the primary plane. However the existing watermark code assumes there's always a primary fb and tries to dereference it to find out pixel format / bpp information. The fix is to make ILK-style watermark calculation actually check the true status of primary & cursor planes and adjust our watermark logic accordingly. v2: Update unchecked uses of state->fb for other platforms (pnv, skl, etc.). Note that this is just a temporary fix. Ultimately the useful information is going to be computed at check time and stored right in the state structures so that we don't have to figure this all out while we're supposed to be programming the watermarks. (caught by Tvrtko) v3: Fix a couple copy/paste mistakes in SKL code. (Tvrtko) v4: Only add FB checks for ILK/SKL codepaths. Older platforms still use intel_crtc_active() and will shortcircuit out of watermark calculations before ever trying to dereference the primary plane's framebuffer.
