My old 845g complains that the child_device_size inside its VBT, version 110, is incorrect. Let's fiddle with the version matching such that it works with this VBT (i.e. treat BIOS v110 as having the same size as v108). Fixes [drm:intel_bios_init] *ERROR* Unexpected child device config size 27 (expected 33 for VBT version 110) Whether this is correct, no one knows - but it works for this particular machine.

We don't actually read out full plane state during driver startup (only whether the primary plane is enabled/disabled), so all of the src/dest rectangles are invalid at this point. However this calculation was needless anyway since we re-calculate them from scratch on the very first atomic transaction after boot anyway. Signed-off-by:

"drm/i915: Make unpin async" doesn't handle the unthrottled cursor updates correctly, leading to an apparent pin count leak. This is caught by the WARN_ON in i915_gem_object_do_pin which screams if we have more than DRM_I915_GEM_OBJECT_MAX_PIN_COUNT pins. Unfortuantely we can't just revert these two because this patch series came with a built-in bisect breakage in the form of temporarily removing the unthrottled cursor update hack for legacy cursor ioctl. Therefore there's no other option than to revert the entire pile :( There's one tiny conflict in intel_drv.h due to other patches, nothing serious. Normally I'd wait a bit longer with doing a maintainer revert, but since the minimal set of patches we need to revert (due to the bisect breakage) is so big, time is running out fast. And very soon (especially after a few attempts at fixing issues) it'll be really hard to revert things cleanly. Lessons learned: - Not a good idea to rush the review (done by someone fairly new to the area) and not make sure domain experts had a chance to read it. - Patches should be properly split up. I only looked at the two patches that should be reverted in detail, but both look like the mix up different things in one patch. - Patches really should have proper commit messages. Especially when doing more than one thing, and especially when touching critical and tricky core code. - Building a patch series and r-b stamping it when it has a built-in bisect breakage is not a good idea. - I also think we need to stop building up technical debt by postponing atomic igt testcases even longer. I think it's clear that there's enough corner cases in this beast that we really need to have the testcases _before_ the next step lands.

On Loading, GuC sets PM interrupts routing (bit 31) and clears ARAT expired interrupt (bit 9). Host turbo also updates this register in RPS flows. This patch ensures bit 31 and bit 9 setup by GuC persists. ARAT timer interrupt is needed in GuC for various features. It also facilitates halting GuC and hence achieving RC6. PM interrupt routing will not impact RPS interrupt reception by host as GuC will redirect them. This patch fixes igt test pm_rc6_residency that was failing with guc load/submission enabled. Tested with SKL GuC v6.1 and BXT GuC v5.1 and v8.7. v2: i915_irq/i915_pm decoupling from intel_guc. (ChrisW) v3: restructuring the mask update and rebase w.r.t Ville's patch.

Daniel Vetter pointed out that vga_switcheroo_client_probe_defer() could be needed by audio clients as well. To avoid mistakes when someone adds conditions for these in the future, constrain the single existing condition to VGA clients by checking for PCI_BASE_CLASS_DISPLAY. This encompasses both PCI_CLASS_DISPLAY_VGA as well as PCI_CLASS_DISPLAY_3D, which is used by some Nvidia Optimus GPUs. Any future checks for audio clients should then be constrained to PCI_BASE_CLASS_MULTIMEDIA. v6: Spun out from commit introducing vga_switcheroo_client_probe_defer() to keep it a pure refactoring change.

So far we've got one condition when DRM drivers need to defer probing on a dual GPU system and it's coded separately into each of the relevant drivers. As suggested by Daniel Vetter, deduplicate that code in the drivers and move it to a new vga_switcheroo helper. This yields better encapsulation of concepts and lets us add further checks in a central place. (The existing check pertains to pre-retina MacBook Pros and an additional check is expected to be needed for retinas.) One might be tempted to check deferred probing conditions in vga_switcheroo_register_client(), but this is usually called fairly late during driver load. The GPU is fully brought up and ready for switching at that point. On boot the ->probe hook is potentially called dozens of times until it finally succeeds, and each time we'd repeat bringup and teardown of the GPU, lengthening boot time considerably and cluttering logfiles. A separate helper is therefore needed which can be called right at the beginning of the ->probe hook. Note that amdgpu currently does not call this helper as the AMD GPUs built into MacBook Pros are only supported by radeon so far. v2: This helper could eventually be used by audio clients as well, so rephrase kerneldoc to refer to "client" instead of "GPU" and move the single existing check in an if block specific to PCI_CLASS_DISPLAY_VGA devices. Move documentation on that check from kerneldoc to a comment. (Daniel Vetter) v3: Mandate in kerneldoc that registration of client shall only happen after calling this helper. (Daniel Vetter) v4: Rebase on 412c8f7d ("drm/radeon: Return -EPROBE_DEFER when amdkfd not loaded") v5: Some Optimus GPUs use PCI_CLASS_DISPLAY_3D, make sure those are matched as well. (Emil Velikov) v6: The if-condition referring to PCI_BASE_CLASS_DISPLAY may be considered a functional change. Move to a separate commit to keep this a pure refactoring change.

The HPFS filesystem used generic_show_options to produce string that is displayed in /proc/mounts. However, there is a problem that the options may disappear after remount. If we mount the filesystem with option1 and then remount it with option2, /proc/mounts should show both option1 and option2, however it only shows option2 because the whole option string is replaced with replace_mount_options in hpfs_remount_fs. To fix this bug, implement the hpfs_show_options function that prints options that are currently selected. Signed-off-by:

Commit c8f33d0b ("affs: kstrdup() memory handling") checks if the kstrdup function returns NULL due to out-of-memory condition. However, if we are remounting a filesystem with no change to filesystem-specific options, the parameter data is NULL. In this case, kstrdup returns NULL (because it was passed NULL parameter), although no out of memory condition exists. The mount syscall then fails with ENOMEM. This patch fixes the bug. We fail with ENOMEM only if data is non-NULL. The patch also changes the call to replace_mount_options - if we didn't pass any filesystem-specific options, we don't call replace_mount_options (thus we don't erase existing reported options).
