mlx4_core: Allocate and map sufficient ICM memory for EQ context

2009-09-24T15:27:16Z

commit fa0681d2129732027355d6b7083dd8932b9b799d upstream. The current implementation allocates a single host page for EQ context memory, which was OK when we only allocated a few EQs. However, since we now allocate an EQ for each CPU core, this patch removes the hard-coded limit (which we exceed with 4 KB pages and 128 byte EQ context entries with 32 CPUs) and uses the same ICM table code as all other context tables, which ends up simplifying the code quite a bit while fixing the problem. This problem was actually hit in practice on a dual-socket Nehalem box with 16 real hardware threads and sufficiently odd ACPI tables that it shows on boot SMP: Allowing 32 CPUs, 16 hotplug CPUs so num_possible_cpus() ends up 32, and mlx4 ends up creating 33 MSI-X interrupts and 33 EQs. This mlx4 bug means that mlx4 can't even initialize at all on this quite mainstream system.

mlx4_en: Fix a kernel panic when waking tx queue

2009-05-30T05:04:42Z

When the transmit queue gets full we enable interrupts for TX completions There was a race that we handled the TX queue both from the interrupt context and from the transmit function. Using "spin_trylock_irq()" ensures this doesn't happen. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S. Miller

mlx4_en: Fix not deleted napi structures

2009-05-18T03:48:59Z

Napi structures are being created each time we open a port, but when the port is closed the napi structure is only disabled but not removed. This bug caused hang while removing the driver. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S. Miller

Remove unreached code in drivers/net/mlx4/en_rx.c

2009-05-12T14:38:09Z

Remove the return after the goto. We want the goto because it frees memory as well as returning err. Found by smatch (http://repo.or.cz/w/smatch.git). Signed-off-by: Dan Carpenter Signed-off-by: Alan Cox Signed-off-by: Linus Torvalds

mlx4_en: Fix cleanup if workqueue create in mlx4_en_add() fails

2009-04-21T08:47:08Z

If creating a workqueue fails, don't jump to the error path where that same workqueue is destroyed, since destroy_workqueue() can't handle a NULL pointer. This was spotted by the Coverity checker (CID 2617). Signed-off-by: Roland Dreier Signed-off-by: David S. Miller
