[PATCH stable-4.19.y backport 1/2] KVM: Pass MMU notifier 'blockable' flag to kvm_unmap_hva_range()

by Will Deacon

commit fdfe7cbd58806522e799e2a50a15aee7f2cbb7b6 upstream. The 'blockable' flag passed to the 'invalidate_range_start()' call back of 'struct mmu_notifier' is used to indicate whether the function is permitted to block. In the case of kvm_mmu_notifier_invalidate_range_start(), this field is not forwarded on to the architecture-specific implementation of kvm_unmap_hva_range() and therefore the backend cannot sensibly decide whether or not to block. Add an extra 'blockable' parameter to kvm_unmap_hva_range() so that architectures are aware as to whether or not they are permitted to block.

[PATCH] drm/etnaviv: fix external abort seen on GC600 rev 0x19

by Christian Gmeiner

It looks like that this GPU core triggers an abort when reading VIVS_HI_CHIP_PRODUCT_ID and/or VIVS_HI_CHIP_CUSTOMER_ID. I looked at different versions of Vivante's kernel driver and did not found anything about this issue or what feature flag can be used. So go the simplest route and do not read these two registers on the affected GPU core.

[PATCH] drm/i915: Break up error capture compression loops with cond_resched()

by Chris Wilson

As the error capture will compress user buffers as directed to by the user, it can take an arbitrary amount of time and space. Break up the compression loops with a call to cond_resched(), that will allow other processes to schedule (avoiding the soft lockups) and also serve as a warning should we try to make this loop atomic in the future.

[PATCH v2] drm/etnaviv: fix external abort seen on GC600 rev 0x19

[PATCH 3/3] xhci: Always restore EP_SOFT_CLEAR_TOGGLE even if ep reset failed

by Mathias Nyman

From: Ding Hui <dinghui(a)sangfor.com.cn> Some device drivers call libusb_clear_halt when target ep queue is not empty. (eg. spice client connected to qemu for usb redir) Before commit f5249461b504 ("xhci: Clear the host side toggle manually when endpoint is soft reset"), that works well. But now, we got the error log: EP not empty, refuse reset xhci_endpoint_reset failed and left ep_state's EP_SOFT_CLEAR_TOGGLE bit still set So all the subsequent urb sumbits to the ep will fail with the warn log: Can't enqueue URB while manually clearing toggle We need to clear ep_state EP_SOFT_CLEAR_TOGGLE bit after xhci_endpoint_reset, even if it failed.
