I have been using it because the same reason as you, but simply didn't noticed that e100 works now ;-)
I switched to e100 and turned debug messages on and got many of these:
BUG: scheduling with irqs disabled: softirq-net-rx//0x00000000/6 caller is schedule+0x10/0x114 [<c0024e24>] (dump_stack+0x0/0x28) from [<c01ae528>] (schedule+0xf8/0x114) [<c01ae430>] (schedule+0x0/0x114) from [<c01afb60>] (rt_lock_slowlock+0x100/0x240) r5 = C01F070C r4 = C4150000 [<c01afa60>] (rt_lock_slowlock+0x0/0x240) from [<c01aff28>] (__lock_text_start+0x18/0x1c) [<c01aff10>] (__lock_text_start+0x0/0x1c) from [<c0078b08>] (kfree+0x2c/0x84) [<c0078adc>] (kfree+0x0/0x84) from [<c002aab0>] (dma_unmap_single+0x110/0x1a8) r5 = C4124BE0 r4 = C7C4B6E0 [<c002a9a0>] (dma_unmap_single+0x0/0x1a8) from [<c012766c>] (e100_poll+0x2e0/0x59c) r8 = C432A3A0 r7 = C41C9BA0 r6 = C41C9B60 r5 = 00000001 r4 = FFC881C0 [<c012738c>] (e100_poll+0x0/0x59c) from [<c0148280>] (net_rx_action+0xa0/0x1a4) [<c01481e0>] (net_rx_action+0x0/0x1a4) from [<c0039020>] (ksoftirqd+0x110/0x1b0) [<c0038f10>] (ksoftirqd+0x0/0x1b0) from [<c00490d8>] (kthread+0x110/0x13c) [<c0048fc8>] (kthread+0x0/0x13c) from [<c0035054>] (do_exit+0x0/0x998) r8 = 00000000 r7 = 00000000 r6 = 00000000 r5 = 00000000 r4 = 00000000 --------------------------- | preempt count: 00000000 ] | 0-level deep critical section nesting: ---------------------------------------- These messages are different as their source seems to be softirq-net-rx. I cannot reproduce the original bug now...
PS: Is latency tracing working on arm platform? I'm unable to get this statistic...
