2016-07-14i40e: use valid online CPU on q_vector initializationGuilherme G. Piccoli1-5/+11
Currently, the q_vector initialization routine sets the affinity_mask of a q_vector based on v_idx value. Meaning a loop iterates on v_idx, which is an incremental value, and the cpumask is created based on this value. This is a problem in systems with multiple logical CPUs per core (like in SMT scenarios). If we disable some logical CPUs, by turning SMT off for example, we will end up with a sparse cpu_online_mask, i.e., only the first CPU in a core is online, and incremental filling in q_vector cpumask might lead to multiple offline CPUs being assigned to q_vectors. Example: if we have a system with 8 cores each one containing 8 logical CPUs (SMT == 8 in this case), we have 64 CPUs in total. But if SMT is disabled, only the 1st CPU in each core remains online, so the cpu_online_mask in this case would have only 8 bits set, in a sparse way. In general case, when SMT is off the cpu_online_mask has only C bits set: 0, 1*N, 2*N, ..., C*(N-1) where C == # of cores; N == # of logical CPUs per core. In our example, only bits 0, 8, 16, 24, 32, 40, 48, 56 would be set. This patch changes the way q_vector's affinity_mask is created: it iterates on v_idx, but consumes the CPU index from the cpu_online_mask instead of just using the v_idx incremental value. No functional changes were introduced. Signed-off-by: Guilherme G Piccoli <[email protected]> Tested-by: Andrew Bowers <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>

2016-07-14i40e/i40evf: Fix i40e_rx_checksumAlexander Duyck2-26/+34
There are a couple of issues I found in i40e_rx_checksum while doing some recent testing. As a result I have found the Rx checksum logic is pretty much broken and returning that the checksum is valid for tunnels in cases where it is not. First the inner types are not the correct values to use to test for if a tunnel is present or not. In addition the inner protocol types are not a bitmask as such performing an OR of the values doesn't make sense. I have instead changed the code so that the inner protocol types are used to determine if we report CHECKSUM_UNNECESSARY or not. For anything that does not end in UDP, TCP, or SCTP it doesn't make much sense to report a checksum offload since it won't contain a checksum anyway. This leaves us with the need to set the csum_level based on some value. For that purpose I am using the tunnel_type field. If the tunnel type is GRENAT or greater then this means we have a GRE or UDP tunnel with an inner header. In the case of GRE or UDP we will have a possible checksum present so for this reason it should be safe to set the csum_level to 1 to indicate that we are reporting the state of the inner header.

2016-07-14Input: synaptics-rmi4 - use of_get_child_by_name() to fix refcountAndrew Duggan1-2/+2
Calling of_find_node_by_name() assumes that the caller has incremented the refcount of the of_node being passed in. Currently, the caller is not incrementing the refcount of the of_node which results in the node being prematurely freed when of_find_node_by_name() calls of_node_put() on it. Instead use of_get_child_by_name() which does not call put on the of_node. Signed-off-by: Andrew Duggan <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2016-07-14nvme: Remove RCU namespace protectionKeith Busch1-35/+39
We can't sleep with RCU read lock held, but we need to do potentially blocking stuff to namespace queues when iterating the list. This patch removes the RCU locking and holds a mutex instead. To prevent deadlocks, this patch removes holding the mutex during namespace scanning and removal. The unlocked namespace scanning is made safe by holding a reference to the namespace being scanned. List iteration that does IO has to be unlocked to allow error recovery. The caller must ensure the list can not be manipulated during such an event, so this patch adds a comment explaining this requirement to the only function that iterates an unlocked list. All callers currently meet this requirement, so no further changes required. List iterations that do not do IO can safely use the lock since it couldn't block recovery from missing forced IO completions.

2016-07-14drm/i915: Ignore panel type from OpRegion on SKLVille Syrjälä1-0/+11
Dell XPS 13 9350 apparently doesn't like it when we use the panel type from OpRegion. The OpRegion panel type (0) tells us to use use low vswing for eDP, whereas the VBT panel type (2) tells us to use normal vswing. The problem is that low vswing results in some display flickers. Since no one seems to know how this stuff is supposed to be handled, let's just ignore the OpRegion panel type on SKL for now. v2: Print the panel type correctly in the debug output Reported-by: James Bottomley <[email protected]> Cc: James Bottomley <[email protected]> Cc: [email protected] References: https://lists.freedesktop.org/archives/intel-gfx/2016-June/098826.html Fixes: a05628195a0d ("drm/i915: Get panel_type from OpRegion panel details") Signed-off-by: Ville Syrjälä <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected] Reviewed-by: Daniel Vetter <[email protected]> Tested-by: James Bottomley <[email protected]> Signed-off-by: Ville Syrjälä <[email protected]> (cherry picked from commit bb10d4ec3be4b069bfb61c60ca4f708f58f440f1) [danvet: Fix up cherry-pick conflict with an s/dev_priv/dev/.] Signed-off-by: Daniel Vetter <[email protected]>

2016-07-14s390/cio: allow to reset channel measurement blockSebastian Ott1-9/+20
Prior to commit 1bc6664bdfb949bc69a08113801e7d6acbf6bc3f a call to enable_cmf for a device for which channel measurement was already enabled resulted in a reset of the measurement data. What looked like bugs at the time (a 2nd allocation was triggered but failed, reset was called regardless of previous failures, and errors have not been reported to userspace) was actually something at least one userspace tool depended on. Restore that behavior in a sane way.
