[1/3] Message-Id: List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-ia64@vger.kernel.org Thanks, all. For the moment, what I mentioned was only about I/O read interface between drivers and MCA handler, and as Zoltan mentioned, something like recovering from each I/O read I/O write DMA from memory to device DMA from device to memory is still left as problem to be solved. I'm glad to hear some comment about this. Well, I'd try to carry out the codes that really consume the data without leaning mf.a. (Since I'm not familiar with IA64 machine instruction now, maybe it takes a long time...) And also, I'd try to check the difference between the readb_check and usual readb. I should reconsider my attempt if the considerable overhead exists. Surely, readb_check concerns the interface for drivers, so I think it is better to consider my plan of discussion on linux-kernel@vger.kern.org. ------ H.Seto
