Date: Wed, 03 Feb 2010 20:33:16 -0800 (PST) From: David Miller <davem@...emloft.net> To: chripell@...e.org Cc: socketcan-core@...ts.berlios.de, netdev@...r.kernel.org Subject: Re: [PATCH net-next-2.6 v3] can: mcp251x: Move to threaded interrupts instead of workqueues. From: Christian Pellegrin <chripell@...e.org> Date: Wed, 3 Feb 2010 18:39:54 +0100 > This patch addresses concerns about efficiency of handling incoming > packets. Handling of interrupts is done in a threaded interrupt handler > which has a smaller latency than workqueues. This change needed a rework > of the locking scheme that was much simplified. Some other (more or less > longstanding) bugs are fixed: utilization of just half of the RX > buffers, useless wait for interrupt on open, more reliable reset > sequence. The MERR interrupt is not used anymore: it overloads the CPU > in error-passive state without any additional information. One shot mode > is disabled because it's not clear if it can be handled efficiently on > this CAN controller. > > Signed-off-by: Christian Pellegrin <chripell@...e.org> Applied. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
