be2net: Replace dma/pci_alloc_coherent() calls with dma_zalloc_coherent()

2015-06-07T22:35:11+00:00

There are several places in the driver (all in control paths) where
coherent dma memory is being allocated using either dma_alloc_coherent()
or the deprecated pci_alloc_consistent(). All these calls should be
changed to use dma_zalloc_coherent() to avoid uninitialized fields in
data structures backed by this memory.

cpumask_set_cpu_local_first => cpumask_local_spread, lament

2015-05-28T01:35:20+00:00

da91309e0a7e (cpumask: Utility function to set n'th cpu...) created a
genuinely weird function.  I never saw it before, it went through DaveM.
(He only does this to make us other maintainers feel better about our own
mistakes.)

cpumask_set_cpu_local_first's purpose is say "I need to spread things
across N online cpus, choose the ones on this numa node first"; you call
it in a loop.

It can fail.  One of the two callers ignores this, the other aborts and
fails the device open.

It can fail in two ways: allocating the off-stack cpumask, or through a
convoluted codepath which AFAICT can only occur if cpu_online_mask
changes.  Which shouldn't happen, because if cpu_online_mask can change
while you call this, it could return a now-offline cpu anyway.

It contains a nonsensical test "!cpumask_of_node(numa_node)".  This was
drawn to my attention by Geert, who said this causes a warning on Sparc.
It sets a single bit in a cpumask instead of returning a cpu number,
because that's what the callers want.

It could be made more efficient by passing the previous cpu rather than
an index, but that would be more invasive to the callers.

bridge/nl: remove wrong use of NLM_F_MULTI

2015-04-29T18:59:16+00:00

NLM_F_MULTI must be used only when a NLMSG_DONE message is sent. In fact,
it is sent only at the end of a dump.

Libraries like libnl will wait forever for NLMSG_DONE.

be2net: Fix a bug in Rx buffer posting

2015-04-09T02:44:27+00:00

The numPosted field in the ERX Doorbell register is 8-bits wide.
So the max buffers that we can post at a time is 255 and not 256
which we are doing currently.

be2net: setup xps queue mapping

2015-03-29T19:34:01+00:00

This patch sets up xps queue mapping on load, so that TX traffic is
steered to the queue whose irqs are being processed by the current cpu.
This helps in avoiding TX lock contention.

be2net: assign CPU affinity hints to be2net IRQs

2015-03-29T19:34:00+00:00

This patch provides hints to irqbalance to map be2net IRQs to
specific CPU cores. cpumask_set_cpu_local_first() is used, which first
maps IRQs to near NUMA cores; when those cores are exhausted, IRQs are
mapped to far NUMA cores.

Conflicts:
	drivers/net/ethernet/emulex/benet/be_main.c
	net/core/sysctl_net_core.c
	net/ipv4/inet_diag.c

The be_main.c conflict resolution was really tricky.  The conflict
hunks generated by GIT were very unhelpful, to say the least.  It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().

So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged.  And this worked beautifully.

The inet_diag.c and sysctl_net_core.c conflicts were simple
overlapping changes, and were easily to resolve.

be2net: use PCI MMIO read instead of config read for errors

2015-03-20T17:25:51+00:00

When an EEH error occurs, the device/slot is disconnected. This condition
is more reliably detected (i.e., returns all ones) with an MMIO read rather
than a config read -- especially on power platforms.

Hence, this patch fixes EEH error detection by replacing config reads with
MMIO reads for reading the error registers. The error registers in
Skyhawk-R/BE2/BE3 are accessible both via the config space and the
PCICFG (BAR0) memory space.
