2020-05-13drm/i915: Handle idling during i915_gem_evict_something busy loopsChris Wilson-14/+12
i915_gem_evict_something() is charged with finding a slot within the GTT that we may reuse. Since our goal is not to stall, we first look for a slot that only overlaps idle vma. To this end, on the first pass we move any active vma to the end of the search list. However, we only stopped moving active vma after we see the first active vma twice. If during the search, that first active vma completed, we would not notice and keep on extending the search list.

2020-05-12RDMA/uverbs: Move IB_EVENT_DEVICE_FATAL to destroy_uobjJason Gunthorpe-7/+10
When multiple async FDs were allowed to exist the idea was for all broadcast events to be delivered to all async FDs, however IB_EVENT_DEVICE_FATAL was missed. Instead of having ib_uverbs_free_hw_resources() special case the global async_fd, have it cause the event during the uobject destruction. Every async fd is now a uobject so simply generate the IB_EVENT_DEVICE_FATAL while destroying the async fd uobject. This ensures every async FD gets a copy of the event. Fixes: d680e88e2013 ("RDMA/core: Add UVERBS_METHOD_ASYNC_EVENT_ALLOC") Link: https://lore.kernel.org/r/20200507063348.98713-3-leon@kernel.org Signed-off-by: Yishai Hadas <yishaih@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2020-05-12RDMA/uverbs: Do not discard the IB_EVENT_DEVICE_FATAL eventJason Gunthorpe-3/+29
The commit below moved all of the destruction to the disassociate step and cleaned up the event channel during destroy_uobj. However, when ib_uverbs_free_hw_resources() pushes IB_EVENT_DEVICE_FATAL and then immediately goes to destroy all uobjects this causes ib_uverbs_free_event_queue() to discard the queued event if userspace hasn't already read() it. Unlike all other event queues async FD needs to defer the ib_uverbs_free_event_queue() until FD release. This still unregisters the handler from the IB device during disassociation. Fixes: 3e032c0e92aa ("RDMA/core: Make ib_uverbs_async_event_file into a uobject") Link: https://lore.kernel.org/r/20200507063348.98713-2-leon@kernel.org Signed-off-by: Yishai Hadas <yishaih@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2020-05-12net: ethernet: ti: Remove TI_CPTS_MOD workaroundClay McClure-11/+7
My recent commit b6d49cab44b5 ("net: Make PTP-specific drivers depend on PTP_1588_CLOCK") exposes a missing dependency in defconfigs that select TI_CPTS without selecting PTP_1588_CLOCK, leading to linker errors of the form: drivers/net/ethernet/ti/cpsw.o: in function `cpsw_ndo_stop': cpsw.c:(.text+0x680): undefined reference to `cpts_unregister' ... That's because TI_CPTS_MOD (which is the symbol gating the _compilation_ of cpts.c) now depends on PTP_1588_CLOCK, and so is not enabled in these configurations, but TI_CPTS (which is the symbol gating _calls_ to the cpts functions) _is_ enabled. So we end up compiling calls to functions that don't exist, resulting in the linker errors. This patch fixes build errors and restores previous behavior by: - ensure PTP_1588_CLOCK=y in TI specific configs and CPTS will be built - remove TI_CPTS_MOD and, instead, add dependencies from CPTS in TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV as below: config TI_CPSW_SWITCHDEV ... depends on TI_CPTS || !TI_CPTS which will ensure proper dependencies PTP_1588_CLOCK -> TI_CPTS -> TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV and build type selection. Note. For NFS boot + CPTS all of above configs have to be built-in.

2020-05-12IB/core: Fix potential NULL pointer dereference in pkey cacheJack Morgenstein-2/+5
The IB core pkey cache is populated by procedure ib_cache_update(). Initially, the pkey cache pointer is NULL. ib_cache_update allocates a buffer and populates it with the device's pkeys, via repeated calls to procedure ib_query_pkey(). If there is a failure in populating the pkey buffer via ib_query_pkey(), ib_cache_update does not replace the old pkey buffer cache with the updated one -- it leaves the old cache as is. Since initially the pkey buffer cache is NULL, when calling ib_cache_update the first time, a failure in ib_query_pkey() will cause the pkey buffer cache pointer to remain NULL. In this situation, any calls subsequent to ib_get_cached_pkey(), ib_find_cached_pkey(), or ib_find_cached_pkey_exact() will try to dereference the NULL pkey cache pointer, causing a kernel panic. Fix this by checking the ib_cache_update() return value.

2020-05-12IB/hfi1: Fix another case where pq is left on waitlistMike Marciniszyn-4/+0
The commit noted below fixed a case where a pq is left on the sdma wait list. It however missed another case. user_sdma_send_pkts() has two calls from hfi1_user_sdma_process_request(). If the first one fails as indicated by -EBUSY, the pq will be placed on the waitlist as by design. If the second call then succeeds, the pq is still on the waitlist setting up a race with the interrupt handler if a subsequent request uses a different SDMA engine Fix by deleting the first call. The use of pcount and the intent to send a short burst of packets followed by the larger balance of packets was never correctly implemented, because the two calls always send pcount packets no matter what. A subsequent patch will correct that issue.

2020-05-11net: ipa: use tag process on modem crashAlex Elder-11/+3
One part of recovering from a modem crash is performing a "tag sequence" of several IPA immediate commands, to clear the hardware pipeline. The sequence ends with a data transfer request on the command endpoint (which is not otherwise done). Unfortunately, attempting to do the data transfer led to a hang, so that request plus two other commands were commented out. The previous commit fixes the bug that was causing that hang. And with that bug fixed we can properly issue the tag sequence when the modem crashes, to return the hardware to a known state. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

2020-05-11drm/i915: Mark concurrent submissions with a weak-dependencyChris Wilson-6/+15
We recorded the dependencies for WAIT_FOR_SUBMIT in order that we could correctly perform priority inheritance from the parallel branches to the common trunk. However, for the purpose of timeslicing and reset handling, the dependency is weak -- as we the pair of requests are allowed to run in parallel and not in strict succession. The real significance though is that this allows us to rearrange groups of WAIT_FOR_SUBMIT linked requests along the single engine, and so can resolve user level inter-batch scheduling dependencies from user semaphores.

2020-05-11ACPI: EC: PM: Avoid premature returns from acpi_s2idle_wake()Rafael J. Wysocki-21/+18
If the EC GPE status is not set after checking all of the other GPEs, acpi_s2idle_wake() returns 'false', to indicate that the SCI event that has just triggered is not a system wakeup one, but it does that without canceling the pending wakeup and re-arming the SCI for system wakeup which is a mistake, because it may cause s2idle_loop() to busy spin until the next valid wakeup event. [If that happens, the first spurious wakeup is still pending after acpi_s2idle_wake() has returned, so s2idle_enter() does nothing, acpi_s2idle_wake() is called again and it sees that the SCI has triggered, but no GPEs are active, so 'false' is returned again, and so on.] Fix that by moving all of the GPE checking logic from acpi_s2idle_wake() to acpi_ec_dispatch_gpe() and making the latter return 'true' only if a non-EC GPE has triggered and 'false' otherwise, which will cause acpi_s2idle_wake() to cancel the pending SCI wakeup and re-arm the SCI for system wakeup regardless of the EC GPE status. This also addresses a lockup observed on an Elitegroup EF20EA laptop after attempting to wake it up from suspend-to-idle by a key press.
