2018-09-14drm/i915/execlists: Reset CSB pointers on canceling requests (wedging)Chris Wilson
The prior assumption was that we did not need to reset the CSB on wedging when cancelling the outstanding requests as it would be cleaned up in the subsequent reset prior to restarting the GPU. However, what was not accounted for was that in preparing for the reset, we would try to process the outstanding CSB entries. If the GPU happened to complete a CS event just as we were performing the cancellation of requests, that event would be kept in the CSB until the reset -- but our bookkeeping was cleared, causing confusion when trying to complete the CS event. v2: Use a sanitize on unwedge to avoid interfering with eio suspend (where we intentionally disable GPU reset).

2018-09-14xen/gntdev: fix up blockable calls to mn_invl_range_startMichal Hocko
Patch series "mmu_notifiers follow ups". Tetsuo has noticed some fallouts from 93065ac753e4 ("mm, oom: distinguish blockable mode for mmu notifiers"). One of them has been fixed and picked up by AMD/DRM maintainer [1]. XEN issue is fixed by patch 1. I have also clarified expectations about blockable semantic of invalidate_range_end. Finally the last patch removes MMU_INVALIDATE_DOES_NOT_BLOCK which is no longer used nor needed. [1] http://lkml.kernel.org/r/20180824135257.GU29735@dhcp22.suse.cz This patch (of 3): 93065ac753e4 ("mm, oom: distinguish blockable mode for mmu notifiers") has introduced blockable parameter to all mmu_notifiers and the notifier has to back off when called in !blockable case and it could block down the road. The above commit implemented that for mn_invl_range_start but both in_range checks are done unconditionally regardless of the blockable mode and as such they would fail all the time for regular calls. Fix this by checking blockable parameter as well. Once we are there we can remove the stale TODO. The lock has to be sleepable because we wait for completion down in gnttab_unmap_refs_sync.

2018-09-14xen/balloon: add runtime control for scrubbing ballooned out pagesMarek Marczykowski-Górecki
Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.

2018-09-14drm/i915: Flush the tasklet when checking for idleChris Wilson
In order to reduce latency when checking for idle we kick the tasklet directly. Sometimes this is not enough as it is queued on another cpu and so to improve the accuracy of this idle-check (and so to reduce latency overall by avoiding another pass, or worse declaring a timeout!) wait for the tasklet to complete.

2018-09-14drm/i915: Limit the backpressure for i915_request allocationChris Wilson
If we try and fail to allocate a i915_request, we apply some backpressure on the clients to throttle the memory allocations coming from i915.ko. Currently, we wait until completely idle, but this is far too heavy and leads to some situations where the only escape is to declare a client hung and reset the GPU. The intent is to only ratelimit the allocation requests and to allow ourselves to recycle requests and memory from any long queues built up by a client hog. Although the system memory is inherently a global resources, we don't want to overly penalize an unlucky client to pay the price of reaping a hog. To reduce the influence of one client on another, we can instead of waiting for the entire GPU to idle, impose a barrier on the local client. (One end goal for request allocation is for scalability to many concurrent allocators; simultaneous execbufs.) To prevent ourselves from getting caught out by long running requests (requests that may never finish without userspace intervention, whom we are blocking) we need to impose a finite timeout, ideally shorter than hangcheck. A long time ago Paul McKenney suggested that RCU users should ratelimit themselves using judicious use of cond_synchronize_rcu(). This gives us the opportunity to reduce our indefinite wait for the GPU to idle to a wait for the RCU grace period of the previous allocation along this timeline to expire, satisfying both the local and finite properties we desire for our ratelimiting. There are still a few global steps (reclaim not least amongst those!) when we exhaust the immediate slab pool, at least now the wait is itself decoupled from struct_mutex for our glorious highly parallel future!

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - DM verity fix for crash due to using vmalloc'd buffers with the asynchronous crypto hadsh API. - Fix to both DM crypt and DM integrity targets to discontinue using CRYPTO_TFM_REQ_MAY_SLEEP because its use of GFP_KERNEL can lead to deadlock by recursing back into a filesystem. - Various DM raid fixes related to reshape and rebuild races. - Fix for DM thin-provisioning to avoid data corruption that was a side-effect of needing to abort DM thin metadata transaction due to running out of metadata space. Fix is to reserve a small amount of metadata space so that once it is used the DM thin-pool can finish its active transaction before switching to read-only mode. * tag 'for-4.19/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm thin metadata: try to avoid ever aborting transactions dm raid: bump target version, update comments and documentation dm raid: fix RAID leg rebuild errors dm raid: fix rebuild of specific devices by updating superblock dm raid: fix stripe adding reshape deadlock dm raid: fix reshape race on small devices dm: disable CRYPTO_TFM_REQ_MAY_SLEEP to fix a GFP_KERNEL recursion deadlock dm verity: fix crash on bufio buffer that was allocated with vmalloc
