2020-09-08drm/i915: fix regression leading to display audio probe failure on GLKKai Vehmanen
In commit 4f0b4352bd26 ("drm/i915: Extract cdclk requirements checking to separate function") the order of force_min_cdclk_changed check and intel_modeset_checks(), was reversed. This broke the mechanism to immediately force a new CDCLK minimum, and lead to driver probe errors for display audio on GLK platform with 5.9-rc1 kernel. Fix the issue by moving intel_modeset_checks() call later. [vsyrjala: It also broke the ability of planes to bump up the cdclk and thus could lead to underruns when eg. flipping from 32bpp to 64bpp framebuffer. To be clear, we still compute the new cdclk correctly but fail to actually program it to the hardware due to intel_set_cdclk_{pre,post}_plane_update() not getting called on account of state->modeset==false.] Fixes: 4f0b4352bd26 ("drm/i915: Extract cdclk requirements checking to separate function") BugLink: https://github.com/thesofproject/linux/issues/2410 Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200901151036.1312357-1-kai.vehmanen@linux.intel.com (cherry picked from commit cf696856bc54a31f78e6538b84c8f7a006b6108b) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2020-09-04Merge branch 'simplify-do_wp_page'Linus Torvalds
Merge emailed patches from Peter Xu: "This is a small series that I picked up from Linus's suggestion to simplify cow handling (and also make it more strict) by checking against page refcounts rather than mapcounts. This makes uffd-wp work again (verified by running upmapsort)" Note: this is horrendously bad timing, and making this kind of fundamental vm change after -rc3 is not at all how things should work. The saving grace is that it really is a a nice simplification: 8 files changed, 29 insertions(+), 120 deletions(-) The reason for the bad timing is that it turns out that commit 17839856fd58 ("gup: document and work around 'COW can break either way' issue" broke not just UFFD functionality (as Peter noticed), but Mikulas Patocka also reports that it caused issues for strace when running in a DAX environment with ext4 on a persistent memory setup. And we can't just revert that commit without re-introducing the original issue that is a potential security hole, so making COW stricter (and in the process much simpler) is a step to then undoing the forced COW that broke other uses.

2020-09-04mm/gup: Remove enfornced COW mechanismPeter Xu
With the more strict (but greatly simplified) page reuse logic in do_wp_page(), we can safely go back to the world where cow is not enforced with writes. This essentially reverts commit 17839856fd58 ("gup: document and work around 'COW can break either way' issue"). There are some context differences due to some changes later on around it: 2170ecfa7688 ("drm/i915: convert get_user_pages() --> pin_user_pages()", 2020-06-03) 376a34efa4ee ("mm/gup: refactor and de-duplicate gup_fast() code", 2020-06-03) Some lines moved back and forth with those, but this revert patch should have striped out and covered all the enforced cow bits anyways.

2020-09-04xen: add helpers to allocate unpopulated memoryRoger Pau Monne
To be used in order to create foreign mappings. This is based on the ZONE_DEVICE facility which is used by persistent memory devices in order to create struct pages and kernel virtual mappings for the IOMEM areas of such devices. Note that on kernels without support for ZONE_DEVICE Xen will fallback to use ballooned pages in order to create foreign mappings. The newly added helpers use the same parameters as the existing {alloc/free}_xenballooned_pages functions, which allows for in-place replacement of the callers. Once a memory region has been added to be used as scratch mapping space it will no longer be released, and pages returned are kept in a linked list. This allows to have a buffer of pages and prevents resorting to frequent additions and removals of regions. If enabled (because ZONE_DEVICE is supported) the usage of the new functionality untangles Xen balloon and RAM hotplug from the usage of unpopulated physical memory ranges to map foreign pages, which is the correct thing to do in order to avoid mappings of foreign pages depend on memory hotplug. Note the driver is currently not enabled on Arm platforms because it would interfere with the identity mapping required on some platforms.

2020-09-03drm/tve200: Stabilize enable/disableLinus Walleij
The TVE200 will occasionally print a bunch of lost interrupts and similar dmesg messages, sometimes during boot and sometimes after disabling and coming back to enablement. This is probably because the hardware is left in an unknown state by the boot loader that displays a logo. This can be fixed by bringing the controller into a known state by resetting the controller while enabling it. We retry reset 5 times like the vendor driver does. We also put the controller into reset before de-clocking it and clear all interrupts before enabling the vblank IRQ. This makes the video enable/disable/enable cycle rock solid on the D-Link DIR-685. Tested extensively.

On my R9 390, the voltage was reported as a constant 1000 mV. This was due to a bug in smu7_hwmgr.c, in the smu7_read_sensor() function, where some magic constants were used in a condition, to determine whether the voltage should be read from PLANE2_VID or PLANE1_VID.

2020-09-02drm/i915: Fix sha_text population codeSean Paul
This patch fixes a few bugs: 1- We weren't taking into account sha_leftovers when adding multiple ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with the beginning of ksv[j] 2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was being placed on the wrong half of sha_text, overlapping the leftover ksv value 3- In the sha_leftovers == 2 case, we need to manually terminate the byte stream with 0x80 since the hardware doesn't have enough room to add it after writing M0 The upside is that all of the HDCP supported HDMI repeaters I could find on Amazon just strip HDCP anyways, so it turns out to be _really_ hard to hit any of these cases without an MST hub, which is not (yet) supported. Oh, and the sha_leftovers == 1 case works perfectly!

2020-09-02drm/i915/display: Ensure that ret is always initialized in ↵Nathan Chancellor
icl_combo_phy_verify_state Clang warns: drivers/gpu/drm/i915/display/intel_combo_phy.c:268:3: warning: variable 'ret' is uninitialized when used here [-Wuninitialized] ret &= check_phy_reg(dev_priv, phy, ICL_PORT_TX_DW8_LN0(phy), ^~~ drivers/gpu/drm/i915/display/intel_combo_phy.c:261:10: note: initialize the variable 'ret' to silence this warning bool ret; ^ = 0 1 warning generated. In practice, the bug this warning appears to be concerned with would not actually matter because ret gets initialized to the return value of cnl_verify_procmon_ref_values. However, that does appear to be a bug since it means the first hunk of the patch this fixes won't actually do anything (since the values of check_phy_reg won't factor into the final ret value). Initialize ret to true then make all of the assignments a bitwise AND with itself so that the function always does what it should do.

When going through a disable/enable cycle without changing the framebuffer the optimization added by commit 3954ff10e06e ("drm/virtio: skip set_scanout if framebuffer didn't change") causes the screen stay blank.

2020-08-31drm/sun4i: Fix dsi dcs long write functionOndrej Jirman
It's writing too much data. regmap_bulk_write expects number of register sized chunks to write, not a byte sized length of the bounce buffer. Bounce buffer needs to be padded too, so that regmap_bulk_write will not read past the end of the buffer.

2020-08-31drm/ingenic: Fix driver not probing when IPU port is missingPaul Cercueil
Even if support for the IPU was compiled in, we may run on a device (e.g. the Qi LB60) where the IPU is not available, or simply with an old devicetree without the IPU node. In that case the ingenic-drm refused to probe. Fix the driver so that it will probe even if the IPU node is not present in devicetree (but then IPU support is disabled of course). v2: Take a different approach Fixes: fc1acf317b01 ("drm/ingenic: Add support for the IPU") Signed-off-by: Paul Cercueil <paul@crapouillou.net> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200827114404.36748-2-paul@crapouillou.net
