This bug existed in the old code, but was easier to fix here in the rework. Unfortunately gen7 doesn't have a nice way to figure out the size and we must use a lookup table.

As a quick hack we make the old intel_gtt structure mutable so we can fool a bunch of the existing code which depends on elements in that data structure. We can/should try to remove this in a subsequent patch. This should preserve the old gtt init behavior which upon writing these patches seems incorrect. The next patch will fix these things. The one exception is VLV which doesn't have the preserved flush control write behavior. Since we want to do that for all GEN6+ stuff, we'll handle that in a later patch. Mainstream VLV support doesn't actually exist yet anyway. v2: Update the comment to remove the "voodoo" Check that the last pte written matches what we readback v3: actually kill cache_level_to_agp_type since most of the flags will disappear in an upcoming patch v4: v3 was actually not what we wanted (Daniel) Make the ggtt bind assertions better and stricter (Chris) Fix some uncaught errors at gtt init (Chris) Some other random stuff that Chris wanted v5: check for i==0 in gen6_ggtt_bind_object to shut up gcc (Ben) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by [v4]: Chris Wilson <chris@chris-wilson.co.uk> [danvet: Make the cache_level -> agp_flags conversion for pre-gen6 a tad more robust by mapping everything != CACHE_NONE to the cached agp flag - we have a 1:1 uncached mapping, but different modes of cacheable (at least on later generations).

This commit makes hsw_fdi_link_train responsible for implementing everything described in the "Enable and train FDI" section from the Hawell CRT mode set sequence documentation. We completely rewrite hsw_fdi_link_train to match the documentation and we also call it in the right place. This patch was initially sent as a series of tiny patches fixing every little problem of the function, but since there were too many patches fixing the same function it got a little difficult to get the "big picture" of how the function would be in the end, so here we amended all the patches into a single big patch fixing the whole function. Problems we fixed: 1 - Train Haswell FDI at the right time. We need to train the FDI before enabling the pipes and planes, so we're moving the call from lpt_pch_enable to haswell_crtc_enable directly. We are also removing ironlake_fdi_pll_enable since the PLL enablement on Haswell is completely different and is also done during the link training steps. 2 - Use the right FDI_RX_CTL register on Haswell There is only one PCH transcoder, so it's always _FDI_RXA_CTL. Using "pipe" here is wrong. 3 - Don't rely on DDI_BUF_CTL previous values Just set the bits we want, everything else is zero. Also POSTING_READ the register before sleeping. 4 - Program the FDI RX TUSIZE register on hsw_fdi_link_train According to the mode set sequence documentation, this is the right place. According to the FDI_RX_TUSIZE register description, this is the value we should set. Also remove the code that sets this register from the old location: lpt_pch_enable. 5 - Properly program FDI_RX_MISC pwrdn lane values on HSW 6 - Wait only 35us for the FDI link training First we wait 30us for the FDI receiver lane calibration, then we wait 5us for the FDI auto training time. 7 - Remove an useless indentation level on hsw_fdi_link_train We already "break" when the link training succeeds. 8 - Disable FDI_RX_ENABLE, not FDI_RX_PLL_ENABLE When we fail the training. 9 - Change Haswell FDI link training error messages We shouldn't call DRM_ERROR when still looping through voltage levels since this is expected and not really a failure. So in this commit we adjust the error path to only DRM_ERROR when we really fail after trying everything. While at it, replace DRM_DEBUG_DRIVER with DRM_DEBUG_KMS since it's what we use everywhere. 10 - Try each voltage twice at hsw_fdi_link_train Now with Daniel Vetter's suggestion to use "/2" instead of ">>1".

We need to set the timing override chicken bit after fdi link training has completed and before we enable the transcoder. We also have to clear that bit again after disabling the pch transcoder. See "Graphics BSpec: vol4g North Display Engine Registers [IVB], Display Mode Set Sequence" and "Graphics BSpec: vol4h South Display Engine Registers [CPT, PPT], South Display Engine Transcoder and FDI Control, Transcoder Debug and DFT, TRANS_CHICKEN_2" bit 31: "Workaround : Enable the override prior to enabling the transcoder. Disable the override after disabling the transcoder." While at it, use the _PIPE macro for the other TRANS_DP register. v2: Keep the w/a as-is, but kill the original (but wrongly placed) workaround introduced in commit 3bcf603f Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Wed Jul 27 11:51:40 2011 -0700 drm/i915: apply timing generator bug workaround on CPT and PPT and commit d4270e57 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Tue Oct 11 10:43:02 2011 -0700 drm/i915: export a CPT mode set verification function Note that this old code has unconditionally set the w/a, which might explain why fdi link training sometimes silently fails, and especially why the auto-train did not seem to work properly. v3: Paulo Zanoni pointed out that this workaround is also required on the LPT PCH. And Arthur Ranyan confirmed that this workaround is requierd for all ports on the pch, not just DP: The important part is that the bit is set whenever the pch transcoder is enabled, and that it is _not_ set while the fdi link is trained. It is also important that the pch transcoder is fully disabled, i.e. we have to wait for bit 30 to clear before clearing the w/a bit. Hence move to workaround into enable/disable_transcoder, where the pch transcoder gets enabled/disabled. v4: Whitespace changes dropped. v5: Don't run the w/a on IBX, we only need it on CPT/PPT and LPT. v6: - resolve conflicts with Paulo's big hsw vga rework - s/!IBX/CPT since hsw paths are now all separate, and Paulo's patch to implement the equivalent w/a for LPT is already merged.
