| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the introduction of BIOS fb preservation, circa 3.17, we began encountering a failure during boot when trying to use force-detect before GEM was initialised. That bug is from commit 7fad798e16fecddd41c6a91728a09f0b9507e40c Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Jul 4 17:51:47 2012 +0200 drm/i915: ensure the force pipe A quirk is actually followed but investigation of the affected machine revealed that it was using a PIPE-A quirk even though it was a 945GSE and the quirk is only supposed to be used to workaround a hardware issue on 830/845. That quirk was added for this HP Mini in commit 6b93afc564a5e74b0eaaa46c95f557449951b3b9 Author: Bryce Harrington <bryce@bryceharrington.org> Date: Wed May 27 03:40:52 2009 -0700 add pipe a force quirk for Dell mini in order to workaround an issue with the BIOS behaving strangely during lid-close. Since then we have a much larger hammer to thwart the BIOS after opening the lid and the PIPE-A quirk is no longer required.

The 15" pre-retina models shipped with 1440x900 (106 MHz) by default or 1680x1050 (119 MHz) as a BTO option, both versions used dual channel LVDS even though the smaller one would have fit into a single channel. Notes: Bug report showing that the MacBookPro8,2 with 1440x900 uses dual channel LVDS (this lead to it being hardcoded in intel_lvds.c by Daniel Vetter with commit 618563e3945b9d0864154bab3c607865b557cecc): https://bugzilla.kernel.org/show_bug.cgi?id=42842 If i915.lvds_channel_mode=2 is missing even though the machine needs it, every other vertical line is white and consequently, only the left half of the screen is visible (verified by myself on a MacBookPro9,1). Forum posting concerning a MacBookPro6,2 with 1440x900, author is using i915.lvds_channel_mode=2 on the kernel command line, proving that the machine uses dual channels: https://bbs.archlinux.org/viewtopic.php?id=185770 Chi Mei N154C6-L04 with 1440x900 is a replacement panel for all MacBook Pro "A1286" models, and that model number encompasses the MacBookPro6,2 / 8,2 / 9,1. Page 17 of the panel's datasheet shows it's driven with dual channel LVDS: http://www.ebay.com/itm/-/400690878560 http://www.everymac.com/ultimate-mac-lookup/?search_keywords=A1286 http://www.taopanel.com/chimei/datasheet/N154C6-L04.pdf Those three 15" models, MacBookPro6,2 / 8,2 / 9,1, are the only ones with i915 graphics and dual channel LVDS, so that list should be complete. And the 8,2 is already in intel_lvds.c. Possible motivation to use dual channel LVDS even on the 1440x900 models: Reduce the number of different parts, i.e. use identical logic boards and display cabling on both versions and the only differing component is the panel.

This avoids the need to specify i915.lvds_channel_mode=2 on all 17" MacBook Pro models with i915 graphics since they had 1920x1200 (193 MHz), plus those 15" pre-retina models which had a resolution of 1680x1050 (119 MHz) as a BTO option.

| * | drm: Zero out invalid vblank timestamp in drm_update_vblank_count.Mario Kleiner2015-05-101-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 844b03f27739135fe1fed2fef06da0ffc4c7a081 we make sure that after vblank irq off, we return the last valid (vblank count, vblank timestamp) pair to clients, e.g., during modesets, which is good. An overlooked side effect of that commit for kms drivers without support for precise vblank timestamping is that at vblank irq enable, when we update the vblank counter from the hw counter, we can't update the corresponding vblank timestamp, so now we have a totally mismatched timestamp for the new count to confuse clients. Restore old client visible behaviour from before Linux 3.17, but zero out the timestamp at vblank counter update (instead of disable as in original implementation) if we can't generate a meaningful timestamp immediately for the new vblank counter. This will fix this regression, so callers know they need to retry again later if they need a valid timestamp, but at the same time preserves the improvements made in the commit mentioned above.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra would not only need a hardware vblank counter that increments at leading edge of vblank, but also support for instantaneous high precision vblank timestamp queries, ie. a proper implementation of dev->driver->get_vblank_timestamp(). Without these, there can be off-by-one errors during vblank disable/enable if the scanout is inside vblank at en/disable time, and additionally clients will never see any useable vblank timestamps when querying via drmWaitVblank ioctl. This would negatively affect swap scheduling under X11 and Wayland.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch 22b3c181c6c324a46f71aae806d8ddbe61d25761 ("arm: dma-mapping: limit IOMMU mapping size") added a check for IO address space size. However this patch broke IOMMU initialization for typical platforms initialized from device tree, which get the default IO address space size of 4GiB. This value doesn't fit into size_t and fails a check introduced by that commit resulting in failed dma-mapping/iommu initialization. This patch fixes this issue by adding proper support for full 4GiB address space size.

Upon closer inspection, there are a few minor differences causing an incorrect decoding and reporting of the master NIU upon an error: 1. The L3_TARG_STDERRLOG_MSTADDR.STDERRLOG_MSTADDR occupies 11 bits on OMAP5 as against 8 bits on OMAP4, with the master NIU connID encoded in the 6 MSBs of the STDERRLOG_MSTADDR field. 2. The CLK3 FlagMux component has 1 input source on OMAP4 and 3 input sources on OMAP5. The common DEBUGSS source is at a different input on each SoC. Fix the above issues by using a OMAP5-specific compatible property and using SoC-specific data where there are differences.
