This patch reads the DRRS support and Mode type from VBT fields. The read information will be stored in VBT struct during BIOS parsing. The above functionality is needed for decision making whether DRRS feature is supported in i915 driver for eDP panels. This information helps us decide if seamless DRRS can be done at runtime to support certain power saving features. This patch was tested by setting necessary bit in VBT struct and merging the new VBT with system BIOS so that we can read the value. v2: Incorporated review comments from Chris Wilson Removed "intel_" as a prefix for DRRS specific declarations. v3: Incorporated Jani's review comments Removed function which deducts drrs mode from panel_type. Modified some print statements. Made changes to use DRRS_NOT_SUPPORTED as 0 instead of -1. v4: Incorporated Jani's review comments. Modifications around setting vbt drrs_type. Signed-off-by:

We have a need for duplicated parsing of the RP_STATE_CAPS register (and the setting of the associated fields). To reuse some code, we can extract the function into a simple helper. This patch also addresses the fact that we missed doing this for gen8, something we should have done anyway. This could be two patches, one to extract, and one to add gen8, but it's trivial enough that I think one is fine. I will accept a request to split it. Please notice the fix addressed by v2 below. Valleyview is left untouched because it is different. v2: Logically rebased on top of commit dd0a1aa1 Author: Jeff McGee <jeff.mcgee@intel.com> Date: Tue Feb 4 11:32:31 2014 -0600 drm/i915: Restore rps/rc6 on reset Note with the above change the fix for gen8 is also handled (which was not the case in Jeff's original patch).

Programming it outside of the rp0-rp1 range is considered a programming error. Since we do not know that the previous value would actually be in the range, program something we've read from the hardware, and therefore know will work. This is potentially an issue for platforms whose ranges are outside the norms given in the programming guide (ie. early silicon) v2: Use RP1 instead of RPn Reviewed-by:

These were apparently meant to protect the SAREA which only has room for two pipes, but things clearly went a bit wonky when first the .update_plane() hooks were split up and then pipe C got introduced. The checks actually protecting the SAREA live in intel_crtc_update_sarea() these days, so the checks in the primary plane update hooks are just historical leftovers which are to be eliminated.

The reg_read whitelist has a gen bitmask to code the gens we're allowing the register to be read on. Until now, it was a literal, but we can be a bit more expressive.

As a result, this initialization code has been moved from the crtc_init() function to the global modeset_init() one.

Instead of reading out the CD clock rate from the HW at each modeset, do this only during driver init and resume and use the cached value during modeset. This moves things towards a state where the sw and hw side setup is separated. It's also needed for VLV RPM, where we don't put device into D0 state until modeset_global_resources is called and thus can't access any display/gfx registers. Signed-off-by:

Brad Volkin authored
Various commands that access memory have a bit to determine whether the graphics address specified in the command should use the GGTT or PPGTT for translation. These checks ensure that the bit indicates PPGTT translation. Most of these checks use the existing bit-checking infrastructure. The PIPE_CONTROL and MI_FLUSH_DW commands, however, are multi-function commands. The GGTT/PPGTT bit is only relevant for certain uses of the command. As such, this change also extends the bit-checking code to include a "condition" mask and offset. If the condition mask is non-zero then the parser only performs the bit check when the bits specified by the condition mask/offset are also non-zero. NOTE: At this point in the series PPGTT must be enabled for the parser to work correctly. If it's not enabled, userspace will not be setting the PPGTT bits the way the parser requires. VLV is the only platform where this is a problem, so at this point, we disable parsing for VLV. v2: whitespace and trailing commas fixes, rebased OTC-Tracker: AXIA-4631 Change-Id: I3f4c76b6734f1956ec47e698230f97d0998ff92b Signed-off-by:

MI_STORE_REGISTER_MEM, MI_LOAD_REGISTER_MEM, and MI_LOAD_REGISTER_IMM commands allow userspace access to registers. Only certain registers should be allowed for such access, so enable checking for those commands. Each ring gets its own register whitelist. MI_LOAD_REGISTER_REG on HSW also allows register access but is currently unused by userspace components. Leave it rejected. PIPE_CONTROL and MEDIA_VFE_STATE allow register access based on certain bits being set. Reject those as well. v2: trailing commas, rebased OTC-Tracker: AXIA-4631 Change-Id: Ie614a2f0eb2e5917de809e5a17957175d24cc44f Signed-off-by:

This file contains all necessary defines, prototypes and typesdefs for manipulating GEN graphics address translation (this does not include the legacy AGP driver) Reiterating the comment in the header, "Please try to maintain the following order within this file unless it makes sense to do otherwise. From top to bottom: 1. typedefs 2. #defines, and macros 3. structure definitions 4. function prototypes Within each section, please try to order by generation in ascending order, from top to bottom (ie. GEN6 on the top, GEN8 on the bottom)." I've made some minor cleanups, and fixed a couple of typos while here - but there should be no functional changes. The purpose of the patch is to reduce clutter in our main header file, making room for new growth, and make documentation of our interfaces easier by splitting things out. With a little more work, like making i915_gtt a pointer, we could potentially completely isolate this header from i915_drv.h. At the moment however, I don't think it's worth the effort. Personally, I would have liked to put the PTE encoding functions in this file too, but I didn't want to rock the boat too much. A similar patch has been in use on my machine for some time. This exact patch though has only been compile tested. Signed-off-by:

Extract all this logic into a new helper function semaphore_wait_to_signaller_ring because: - The current code has way too much magic. - The current code doesn't look at bi16, which encodes VECS signallers on HSW. Those are just added after the fact, so can't be encoded in a neat formula. - The current logic can't blow up since it limits its value range sufficiently, but that's a bit too tricky to rely on in my opinion. Especially when we start to add bdw support. - I'm not a big fan of the explicit ring->semaphore_register list, but I think it's more robust to use the same mapping both when constructing the semaphore commands and when decoding them. - Finally add a FIXME comment about lack of broadwell support here, like in the earlier ipehr semaphore cmd detection function.

The documentation calls this GFX_MODE bit "Flush TLB invalidate Mode". However, that is not a good name for an enable bit as it doesn't make it clear what is enabled. An even worse name is GFX_TLB_INVALIDATE_ALWAYS as enabling that bit actually prevents the TLB from being invalidated at every flush. This leads to great confusion when reading code and proposed patches. To get around this try to bake in what is enabled by setting the bit and call it GFX_TLB_INVALIDATE_EXPLICIT. Signed-off-by:

If runtime PM is enabled and we unset all modes, we will runtime suspend after __intel_set_mode() , then function intel_modeset_check_state() will try to read the HW state while it is suspended and trigger lots of WARNs because it shouldn't be reading registers. So on this patch we make intel_ddi_connector_get_hw_state() return false in case the power domain is disabled, and we also make intel_display_power_enabled() return false in case the device is suspended. Notice that we can't just use intel_display_power_enabled_sw() because while the driver is being initialized the power domain refcounts are not reflecting the real state of the hardware. Just for reference, I have previously published an alternate patch for this problem, called "drm/i915: get runtime PM at intel_set_mode". Testcase: igt/pm_pc8 Signed-off-by:
