[PATCH v2 1/6] OPP: Fix support for required OPPs for multiple PM domains

by Ulf Hansson

It has turned out that having _set_required_opps() to recursively call dev_pm_opp_set_opp() to set the required OPPs, doesn't really work as well as we expected. More precisely, at each recursive call to dev_pm_opp_set_opp() we are changing the OPP for a genpd's OPP table for a device that has been attached to it. The problem with this, is that we may have several devices being attached to the same genpd, thus sharing the same OPP-table that is being used for their required OPPs. So, typically we may have several active requests simultaneously for different OPPs for a genpd's OPP table. This may lead to that the per device vote for a performance-state (opp-level) for a genpd doesn't get requested accordingly. Moreover, dev_pm_opp_set_opp() doesn't get called for a required OPP when a device has been attached to a single PM domain. Even if a consumer driver would attempt to assign the required-devs, via _opp_attach_genpd() or _opp_set_required_devs() it would not be possible, as there is no separate virtual device at hand to use in this case. The above said, let's fix the problem by replacing the call to dev_pm_opp_set_opp() in _set_required_opps() by a call to _set_opp_level(). At the moment there's no drawback doing this, as there is no need to manage anything but the performance-state of the genpd. If it later turns out that another resource needs to be managed for a required-OPP, it can still be extended without having to call dev_pm_opp_set_opp().

[PATCH v2] clk: davinci: da8xx-cfgchip: Initialize clk_init_data before use

by Bastien Curutchet

The flag attribute of the struct clk_init_data isn't initialized before the devm_clk_hw_register() call. This can lead to unexpected behavior during registration. Initialize the entire clk_init_data to zero at declaration.

[PATCH 6.6 0/3] Backport VFIO refactor to fix fork ordering bug

by Axel Rasmussen

35e351780fa9 ("fork: defer linking file vma until vma is fully initialized") switched the ordering of vm_ops->open() and copy_page_range() on fork. This is a bug for VFIO, because it causes two problems: 1. Because open() is called before copy_page_range(), the range can conceivably have unmapped 'holes' in it. This causes the code underneath untrack_pfn() to WARN. 2. More seriously, open() is trying to guarantee that the entire range is zapped, so any future accesses in the child will result in the VFIO fault handler being called. Because we copy_page_range() *after* open() (and therefore after zapping), this guarantee is violated. We can't revert 35e351780fa9, because it fixes a real bug for hugetlbfs. The fix is also not as simple as just reodering open() and copy_page_range(), as Miaohe points out in [1]. So, although these patches are kind of large for stable, just backport this refactoring which completely sidesteps the issue. Note that patch 2 is the key one here which fixes the issue. Patch 1 is a prerequisite required for patch 2 to build / work. This would almost be enough, but we might see significantly regressed performance. Patch 3 fixes that up, putting performance back on par with what it was before. Note [1] also has a more full discussion justifying taking these backports. I proposed the same backport for 6.9 [2], and now for 6.6. 6.6 is the oldest kernel which needs the change: 35e351780fa9 was reverted for unrelated reasons in 6.1, and was never backported to 5.15 or earlier.

[PATCH v4 1/4] drm/vmwgfx: Fix a deadlock in dma buf fence polling

by Zack Rusin

Introduce a version of the fence ops that on release doesn't remove the fence from the pending list, and thus doesn't require a lock to fix poll->fence wait->fence unref deadlocks. vmwgfx overwrites the wait callback to iterate over the list of all fences and update their status, to do that it holds a lock to prevent the list modifcations from other threads. The fence destroy callback both deletes the fence and removes it from the list of pending fences, for which it holds a lock. dma buf polling cb unrefs a fence after it's been signaled: so the poll calls the wait, which signals the fences, which are being destroyed. The destruction tries to acquire the lock on the pending fences list which it can never get because it's held by the wait from which it was called. Old bug, but not a lot of userspace apps were using dma-buf polling interfaces. Fix those, in particular this fixes KDE stalls/deadlock.
