is_pch_edp() will be removed in a follow-up patch, so replace it with a check for the port and VBT info (for port-D eDP). Also make things a bit clearer by using a switch on the ports. v2: - make the comment about not setting the conder type for DP clearer (Ville) Signed-off-by:

In some cases, we may not need GTT address space allocated to a stolen object, so allow passing -1 to the preallocated function to indicate as much. v2: remove BUG_ON(gtt_offset & 4095) now that -1 is allowed (Ville) Reviewed-by:

But we need to get the right stolen base and make pre-allocated objects for BIOS stuff so we don't clobber it. If the BIOS hasn't allocated a power context, we allocate one here too, from stolen space as required by the docs. v2: fix stolen to phys if ladder (Ben) keep BIOS reserved space out of allocator altogether (Ben) v3: fix mask of stolen base (Ben) v4: clean up preallocated object on unload (Ben) don't zero reg on unload (Jesse) fix mask harder (Jesse) v5: use unref for freeing stolen bits (Chris) move alloc/free to intel_pm.c (Chris) v6: NULL pctx at disable time so error paths work (Ben) v7: use correct PCI device for config read (Jesse) Reviewed-by:Ben Widawsky <benjamin.widawsky@intel.com> Signed-off-by:

If the calculated FBC watermark is no good, we simply disable FBC watermarks. But we fail to re-enable them later if the calculated watermark becomes good again. Fix that, but remember to leave FBC watermarks disabled on ILK since that's required by some workarounds. v2: Fix checkpatch complaint Signed-off-by:

commit 142e2398 Author: Egbert Eich <eich@suse.de> Date: Thu Apr 11 15:57:57 2013 +0200 drm/i915: Add bit field to record which pins have received HPD events (v3) added a bit field for hotplug event tracking. There ended up being three different v3 of the patch: [1], [2], and [3]. Apparently [1] was the correct one, but some frankenstein combination of the three got committed, which reversed the logic for setting the hotplug bits and misplaced a continue statement, skipping the hotplug irq storm handling altogether. This lead to broken hotplug detection, bisected to commit 321a1b30 Author: Egbert Eich <eich@suse.de> Date: Thu Apr 11 16:00:26 2013 +0200 drm/i915: Only reprobe display on encoder which has received an HPD event (v2) which uses the incorrectly set hotplug event bits.

Paulo Zanoni authored
In the error state function we read the registers without checking if the power well is on, so after doing this we have to clear the FPGA_DBG_RM_NOCLAIM bit to prevent the next I915_WRITE from detecting it and printing an error message. The first version of this patch was checking for the power well state and then avoiding reading registers that were off, but the reviewers requested to just read the registers any way and then later clear the FPGA_DBG_RM_NOCLAIM bit.

This should replace intel_using_power_well. The idea is that we're adding the requested power domain as an argument, so this might enable the code to look less platform-specific and also allows us to easily add new domains in case we need. v2: Add more domains to enum intel_display_power_domain v3: Even more domains requested Requested-by:

Supposedly we should use the DAC divider for <300MHz pixel clocks, but as that doesn't actually work as well as the high freq divider here in practice, just use the high freq divider all the time. v2: remove unconditional write (Jesse) check for pixel rate properly (Jesse) v3: give up, the DAC divider apparently doesn't work, and low res modes work ok (Jesse) remove debug msg (Jesse) Signed-off-by:Kenneth Graunke <kenneth@whitecape.org> Signed-off-by:

This regression was introduced in: commit b074cec8 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Thu Apr 25 12:55:02 2013 -0700 drm/i915: move PCH pfit controls into pipe_config In refactoring this, it was only applied to eDP, which is incorrect.

It also makes some sense IMO to have these two functions separate irrespective of the number of callers. Only the single caller for now, but that will change as we add more PPGTTs. Signed-off-by:
-
Ben Widawsky authored
Because PPGTT PDEs within the GTT are calculated in cachelines (HW guys consistency ftw) we do a divide which will wreak havoc if this is wrong, and I know that from experience). If/when we move to multiple PPGTTs this will have to become a WARN, and return an error. For now however it should always be considered fatal, and only a developer could hit it. Signed-off-by:

Because our context refcounting doesn't grab a ref at lookup time, it is unsafe to do so without the lock. NOTE: We don't have an easy way to put the assertion in the lookup function which is where this really belongs. Context switching is good enough because it actually asserts even more correctness by protecting the default_context. Signed-off-by:

While at it, also extract a common helper to copy the timings from the cpu transcoder to the pch transcoder. That way it's really explicit how the lpt transcoder is hardcoded. v2: - Re-align #defines properly (Paulo). - Use cpu_transcoder when copying pipe timings (Paulo). - s/intel_pch_transcoder_enable/intel_pch_transcoder_set_timings/ since we already have a pch transcoder enable function, and this is clearer, too. - Fixup 80 char line overflow in intel_display.c. I've opted to ignore this in i915_reg.h and i915_ums.c since meh. Cc: Paulo Zanoni <przanoni@gmail.com> Reviewed-by:

With the hw state readout&check code it's important that the values we keep around are the canonical ones. Unfortunately when adding the pipe timings readout support I've missed that the write side adjusts the timings in the pipe config. Fix this up and so prevent the unsightly WARN noise in dmesg.

Chris Wilson authored
In order to be notified of when the context and all of its associated objects is idle (for if the context maps to a ppgtt) we need a callback from the retire handler. We can arrange this by using the kref_get/put of the context for request tracking and by inserting a request to demarque the switch away from the old context.

If we ever leak a non-DP compliant port width through here, we have a pretty serious issue. So just rip out all these WARNs - if we need them it's probably better to have them at a central place where we compute the dp lane count. Also use the new DDI width macro for FDI mode.

Enabling PPGTT and also the need to track which context was guilty of gpu hang (arb robustness enabling) have put pressure for struct i915_hw_context to be more than just a placeholder for hw context state. In order to track object lifetime properly in a multi peer usage, add reference counting for i915_hw_context. v2: track i915_hw_context pointers instead of using ctx_ids (from Chris Wilson) v3 (Ben): Get rid of do_release() and handle refcounting more compactly. (recommended by Chis) v4: kref_* put inside static inlines (Daniel Vetter) remove code duplication on freeing context (Chris Wilson) v5: idr_remove and ctx->file_priv = NULL in destroy ioctl (Chris) This actually will cause a problem if one destroys a context and later refers to the idea of the context (multiple contexts may have the same id, but only 1 will exist in the idr). v6: Strip out the request related stuff.

Ville Syrjälä authored
Properly clip the source when the destination gets clipped by the pipe dimensions. Sadly the video sprite hardware is rather limited so it can't do proper sub-pixel postitioning. Resort to truncating the source coordinates to (macro)pixel boundary. The scaling checks are done using the strict drm_region functions. Which means that an error is returned when the min/max scaling ratios are exceeded. Also do some additional checking against various hardware limits. v2: Truncate src coords instead of rounding to avoid increasing src viewport size, and adapt to changes in drm_calc_{h,v}scale(). v3: Adapt to drm_region->drm_rect rename. Fix misaligned crtc_w for packed YUV formats when scaling isn't supported. v4: Use stricter scaling checks, use drm_rect_equals() v5: If sprite is below min size, make it invisible instead returning an error. Use WARN_ON() instead if BUG_ON(), and add one to sanity check the src viewport size. v6: Add comments to remind about src and dst coordinate types Reviewed-by:
