This capability allows user space to control the delivery of modes with the 3D flags set. This is to not play games with current user space users not knowing anything about stereo 3D flags and that could try to set a mode with one or several of those bits set. So, the plan is to remove the stereo modes from the list of modes we give to DRM clients by default, and let them through if we are being told otherwise. stereo_allowed is bound to the drm_file structure to make it a per-client setting, not a global one. v2: Replace clearing 3D flags by discarding the stereo modes now that they are regular modes. v3: SET_CAP -> SET_CLIENT_CAP rename (Chris Wilson) Reviewed-by:Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

HDMI 1.4a defines a few layouts that we'd like to expose. This commits add new modeinfo flags that can be used to list the supported stereo layouts (when querying the list of modes) and to set a given stereo 3D mode (when setting a mode). v2: Add a drm_mode_is_stereo() helper Reviewed-by:

This ioctl can be used to turn some knobs in a DRM driver. The client can ask the DRM core for an alternate view of the reality: it can be useful to be able to instruct the core that the DRM client can handle new functionnality that would otherwise break current ABI. v2: Rename to ioctl from SET_CAP to SET_CLIENT_CAP (Chris Wilson) Reviewed-by:

It's a tiny bit more logical to find the different capabilities you can use with the GET_CAP ioctl next to the structure rather than putting them at the end of the file. v2: Tab align the litterals (David Herrmann) v3: Make it clearer that DRM_PRIME_CAP_EXPORT/IMPORT are flags of DRM_CAP_PRIME. v4: Rebase on top of latest bits (DRM_CAP_ASYNC_PAGE_FLIP was introduced) Reviewed-by: David Herrmann <dh.herrmann@gmail.com> (for v2) Signed-off-by: -

So that we can find the callers who introduce a ring stall. A single ring stall is not too unwelcome, the right issue becomes when they start to interlock and prevent any concurrent work. That, however, is a little tricker to detect with a mere tracepoint! v2: Rebrand it as a ring event, rather than an object event. v3: Include the seqno in the tracepoint for posterity or something.

Even though we track object activity and not VMA, because we have the active_list be based on the VM, it makes the most sense to use VMAs in the APIs. NOTE: Daniel intends to eventually rip out active/inactive LRUs, but for now, leave them be. v2: Remove leftover hunk from the previous patch which didn't keep i915_gem_object_move_to_active. That patch had to rely on the ring to get the dev instead of the obj. (Chris) Reviewed-by:

"We do fairly often lookup the ggtt vma for an obj." - Chris Wilson. As such, provide a function to offer slightly cheaper access to the vma. Not performance tested. By my quick estimation it saves at least 3 pointer dereferences from the existing mechanism.

Daniel complained that we keep adding stuff to the bottom of the file, so we constantly have conflicts. So reorganize everything and split them file-by-file, also sorting the files in alphabetical order. This way, patches touching different files will have a smaller chance of conflicting. Of course, this commit will conflict with everybody on the list :) Also remove a few useless comments and make some things fit into 80 lines. v2: - Conflict with intel_ddi_get_config Requested-by:

Flat out skip anything to do with PLL if we have a DSI encoder (and thus DSI PLL). Also skip PLL computation if the encoder has already set clocks. This allows for some tidying up of the code, including a superfluous call to intel_limit() for LVDS downclock path. Signed-off-by:

Obtaining the forcwake requires expensive and time consuming serialisation. And we often try to obtain the forcewake multiple times in very quick succession. We can reduce the overhead of these sequences by delaying the forcewake release, and so not hammer the hw quite so hard. I was hoping this would help with the spurious [drm:__gen6_gt_force_wake_mt_get] *ERROR* Timed out waiting for forcewake old ack to clear. found on Haswell. Alas not. v2: Fix teardown ordering - unmap the regs after turning off forcewake, and make sure we do turn off forcewake - both found by Ville. v3: As we introduce intel_uncore_fini(), use it to make sure everything is disabled before we hand back to the BIOS. Note: I have no claims for improved performance, stablity or power comsumption for this patch. We should not be hitting the registers often enough for this to improve benchmarks, but given the nature of our hw it is likely to improve long term stability. Signed-off-by:

The VGA plane needs to be disabled before we start doing any modeset operations on resume. This should also guarantee that the power well will be enabled when we call i915_redisable_vga() since it gets explicitly powered on during resume, and will get powered back off during the modeset operation if no longer needed.

VGA registers live inside the power well on HSW, so in order to write the VGA MSR register we need the power well to be on. We really must write to the register to properly clear the VGA_MSR_MEM_EN enable bit, even if all VGA registers get zeroed when the power well is down. It seems that the implicit zeroing done by the power well is not enough to propagate the VGA_MSR_MEM_EN bit to whomever is actually responsible for the memory decode ranges. If we leave VGA memory decode enabled, and then turn off the power well, all VGA memory reads will return zeroes. But if we first disable VGA memory deocde and then turn off the power well, VGA memory reads return all ones, indicating that the access wasn't claimed by anyone. For the vga arbiter to function correctly the IGD must not claim the VGA memory accesses. Previously we were doing the VGA_MSR register access while the power well was excplicitly powered up during driver init. But ever since commit 6e1b4fda Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Thu Sep 5 20:40:52 2013 +0300 drm/i915: Delay disabling of VGA memory until vgacon->fbcon handoff is done we delay the VGA memory disable until fbcon has initialized, and so there's a possibility that the power well got turned off during the fbcon modeset. Also vgacon_save_screen() will need the power well to be on to be able to read the VGA memory. So immediately after enabling the power well during init grab a refence for VGA purposes, and after all the VGA handling is done, release it. v2: Add intel_display_power_put() for the num_pipes==0 case Signed-off-by:

It only controls the setting of the vbt.edp_support variable, which in turn only controls one debug output plus can also force-disable the lvds output. Since the value only restricted this logic to mobile ilk there's the slight risk that this will break lvds on desktop ilk or on snb/ivb platforms. But with the vbt it's better when we know what's going on here, so let's rip it out and see what happens.

There's no reason to init a DP connector if the encoder just supports HDMI: we'll just waste hundreds and hundreds of cycles trying to do DP AUX transactions to detect if there's something there.

Our code makes a lot of assumptions regarding what each DDI port actually supports, and the VBT should tell us what is really happening in the hardware. So parse the information provided by the VBT and check if any of our assumptions is wrong. Our driver also has a history of not really trusting the VBT, so a WARN here could mean that: a) our coding assumptions are wrong b) the VBT is wrong c) we're incorrectly parsing the VBT d) the checks are wrong But I really hope we won't ever trigger any of those WARNs. v2: Don't check the redundant "Capabilities" field from byte 24 since it doesn't seem to be used. v3: Rebase v4: Replace WARN with DRM_DEBUG_KMS Signed-off-by: -

Our code currently assumes that port X will use the DP AUX channel X and the DDC pin X. The VBT should tell us how things are mapped, so add some WARNs in case we discover our assumptions are wrong (or in case the VBT is just wrong, which is also perfectly possible). Why would someone wire port B to AUX C and DDC D? v2: Rebase v3: Convert WARNs to DRM_DEBUG_KMS Signed-off-by:

We currently use the recommended values from BSpec, but the VBT specifies the correct value to use for the hardware we have, so use it. We also fall back to the recommended value in case we can't find the VBT. In addition, this code also provides some infrastructure to parse more information about the DDI ports. There's a lot more information we could extract and use in the future. v2: - Move some code to init_vbt_defaults. v3: - Rebase - Clarify the "DVO Port" matching code v4: - Use I915_MAX_PORTS - Change the HAS_DDI checks - Replace DRM_ERROR with DRM_DEBUG_KMS Signed-off-by: -

We currently treat the child_device_config as a simple struct, but this is not correct: new BDB versions change the meaning of some offsets, so the struct needs to be adjusted for each version. Since there are too many changes (today we're in version 170!), making a big versioned union would be too complicated, so child_device_config is now a union of 3 things: (i) a "raw" byte array that's safe to use anywhere; (ii) an "old" structure that's the one we've been using and should be safe to keep in the SDVO and TV code; and (iii) a "common" structure that should contain only fields that are common for all the known VBT versions.
