Bug #310

BQL patch fails on 3.1.1

Added by Dave Täht on Nov 25, 2011. Updated on Apr 21, 2012.
Closed Normal Dave Täht

Description

Same patch works on same kernel version, must be a problem with a .config conflict

just feel the un-merged pain… there are dozens of machines here not in the mainline kernel.

cerowrt/target/linux/ar71xx/files/arch/mips/ar71xx

Updated by Dave Täht on Nov 25, 2011.
and basically the update to 3.2 moved a ton of dirs around.
Updated by Dave Täht on Dec 5, 2011.
It turned out I had deeper problems. It turned out all of 3.1.1 was failing to build.

Still unfixed.

3.0 is also failing to build.

Updated by Dave Täht on Dec 12, 2011.
3.1.5 finally built after backing out multiple changes to find the problem, and getting a new patchset from the net.
Updated by Dave Täht on Jan 28, 2012.
I have successfully backported BQL to 3.2.2 and tested on x86 with the e1000e driver.

My attempt at wedging BQL support into the ag71xx driver, however, fails. It does
get one packet out… So I have to look harder at the relevant drivers and see where
I went wrong.

I got it working… now to test.

I am happy to report I got bql backported to 3.2.2 successfully. Or so I think.

Please enable this option when you configure your kernel, using ‘make menuconfig’.

Networking support --> Networking options --> RPS

Because ‘struct netdev_queue’ has the member ‘kobj’ only when CONFIG_RPS is defined.
So does ‘queues_kset’ in ‘struct net_device’.

You can find the definition in ‘include/linux/netdevice.h’.

struct net_device {
...
#ifdef CONFIG_RPS
    struct kset     *queues_kset;
    struct netdev_rx_queue  *_rx;
    /* Number of RX queues allocated at register_netdev() time */
    unsigned int        num_rx_queues;
    /* Number of RX queues currently active in device */
    unsigned int        real_num_rx_queues;
#ifdef CONFIG_RFS_ACCEL
    /* CPU reverse-mapping for RX completion interrupts, indexed by RX queue number. Assigned by driver.
     * This must only be set if the ndo_rx_flow_steer operation is defined. */
    struct cpu_rmap     *rx_cpu_rmap;
#endif
#endif
...
};
...
struct netdev_queue {
...
#ifdef CONFIG_RPS
    struct kobject      kobj;
#endif
...
} ____cacheline_aligned_in_smp;

Have a good day!
