Thank you all for help with my last patch. I found one more entry in my notes that could be a bug, or could be a misunderstanding on my part. The memory map in DocID15818 (Rev 15) datasheet says: ADC1 - ADC2 - ADC3: 0x40012000-0x400123FF That suggests a size of 0x400 (they share that

Hi Peter, I am chasing an address translation error, and it looks like it might be a QEMU bug, because I cannot reproduce the problem on a physical board. The issue is that a requested ATS12NSOPW translation in Xen is reported as failing by QEMU, but actually the address is correct. The workflow

Recently I hear that the experimental x-data-plane feature from virtio-blk was production-ready and that virtio-scsi also got support for it, so, after finding what the new syntax is: http://comments.gmane.org/gmane.comp.emulators.qemu/279118 ...I decided to test it. After all, it was supposed
