[PATCH 1/2] virtio: Reduce BUG if total_sg > virtqueue size to WARN.
On Thu, Aug 10, 2017 at 05:40:34PM +0100, Richard W.M. Jones wrote: > If using indirect descriptors, you can make the total_sg as large as > you want. That would be a spec violation though, even if it happens to work on current QEMU. The spec says: A driver MUST NOT create a descriptor chain longer than the Queue Size of the device. What prompted this patch? Do we ever encounter this

[LLVMdev] Illegal optimization in LLVM 2.8 during SelectionDAG? (Re: comparison pattern trouble - might be a bug in LLVM 2.8?)

The original code is: #include <stdio.h> typedef unsigned char e_u8; typedef unsigned short e_u16; e_u16 Calc_crc8(e_u8 data, e_u16 crc ) __attribute((__noinline__)); e_u16 Calc_crc8(e_u8 data, e_u16 crc ) { e_u8 i,x16,carry; for (i = 0; i < 2; i++) { x16 = (e_u8)(((data) ^ ((e_u8)crc))&1); if (x16 == 1) {...

Design: Adding checksums to index files
...ause it requires file format changes that old Dovecots can't then read. I could probably patch v2.1 also so it is able to at least read the new format without failing. For v2.3 this new format could then be made the default. And what would the checksums be exactly? Would the standard CRC32 and CRC8 work fine, or are there any better ones? 1. dovecot.index v2.1+ always only fully recreates this file, never overwrites data to it. So the checksums could be written only when the dovecot.index is being recreated. There are 3 possible things to checksum: - header (32bit checksum) - all of the...

[LLVMdev] Lowering to return multiple values: codeGen, instruction write one value to the input register.
Hi All, In XCore backend, I saw “ …... EVT VT = Op.getValueType(); SDValue Data = DAG.getNode(XCoreISD::CRC8, DL, DAG.getVTList(VT, VT), Op.getOperand(1), Op.getOperand(2) , Op.getOperand(3)); SDValue Crc(Data.getNode(), 1); SDValue Results[] = { Crc, Data }; return DAG.getMergeValues(Results, 2, DL); “ which is used to lower an instruction that returns two values....

guestfish hang when exec command.
Hi, I have some issues with libguestfs. I download the libguestfs-0.18.3 source code and read the README file. it requested qemu >= 0.13, my qemu version is qemu-1.0.1 requested kernel version >= 2.6.34, my kernel version is 3.1.4 the most of requirement for compiling I reached. but I completed compiltion and executed command. the guestfish hang there. the following was my operating steps:
