From 5ccc921af41a862fe969809228f029035f851502 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 23 Sep 2013 11:37:59 -0700 Subject: intel: Remove extern from function prototypes There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

This furthers work which was requested by Linus Torvalds when the initial busy poll code was included in the kernel. The code in the ixgbe driver itself was never properly renamed to reflect the change to busy polling as the title.

The original author did not realize that napi_disable might sleep, which would cause a sleep while atomic BUG. In addition, on a single processor system, the ixgbe_qv_lock_napi loop shouldn't have to mdelay. This patch adds an ixgbe_qv_disable along with a new IXGBE_QV_STATE_DISABLED bit, which it uses to indicate to the poll and napi routines that the q_vector has been disabled. Now the ixgbe_napi_disable_all function will wait until all pending work has been finished and prevent any future work from being started.

It currently uses 512 pages, regardless of page size. During receive handling it adds the unused part of the page back into the rx ring, avoiding the need for a new allocation. On a ppc64 box with 64 threads and 64kB pages, we end up with 512 entries * 64 rx queues * 64kB = 2GB memory used. Even more of a concern is that we use up 2GB of IOMMU space in order to map all this memory. The driver makes a number of decisions based on if PAGE_SIZE is less than 8kB, so use this as the breakpoint and only allocate 128 entries on 8kB or larger page sizes.

The fix is first to remove unnecessary references to num_rx_queues. Because the hardware offload case is limited to cases where RX queues and TX queues are equal we only need a single check. Then wrap the single case in an ifdef.

This is in turn used by the queue allocation scheme to determine how many queues are needed to support the number of pools in use with the current feature set. This works as long as the pools are added and destroyed in order because (num_rx_pools * queues_per_pool) is equal to the last queue in use by a pool. But as soon as you delete a pool out of order this is no longer the case. So the above multiplication allocates to few queues and a pool may reference a ring that has not been allocated/initialized. To resolve use the bit mask of in use pools to determine the final pool being used and allocate enough queues so that we don't inadvertently remove its queues. # ip link add link eth2 \ numtxqueues 4 numrxqueues 4 txqueuelen 50 type macvlan # ip link set dev macvlan0 up # ip link add link eth2 \ numtxqueues 4 numrxqueues 4 txqueuelen 50 type macvlan # ip link set dev macvlan1 up # for i in {0..100}; do ip link set dev macvlan0 down; ip link set dev macvlan0 up; done; Signed-off-by: John Fastabend Acked-by: Neil Horman Acked-by: Jeff Kirsher Signed-off-by: David S.

The max_vfs parameter has a limit of 63 and silently fails (adding 0 vfs) when it is out of range. This patch adds a warning so that the user knows something went wrong. Also, this patch moves the warning in ixgbe_enable_sriov() to where max_vfs is checked, so that even an out of range value will show the deprecated warning. Previously, an out of range parameter didn't even warn the user to use the new sysfs interface instead.
