Message-ID: <AANLkTikT3ThBnO8q3AvhS9t4jUu8npOwYmjY6WUMhseq@mail.gmail.com> Date: Wed, 19 May 2010 23:18:40 +0800 From: zhou rui <wirelesser@...il.com> To: netdev@...r.kernel.org Subject: how many msi (msi-x) vectors can be setup? hi there: how many msi (msi-x) vectors can be setup? the number is limited by hardware resource(nic), or kernel ? I found that the driver (broadcom 57711 ver 1.5.12) tried to request 16 queues on my kernel2.6.27,but only 2 available will it be increased if I update the driver or kernel? and there is a limitiation in the system? if the other devices have already occupied too many MSI vectors then it is not enough. thanks rui -- 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
