This patch corrects several misbehaviors during an interrupt process. Most of the time the pc is already correct and therefore no special treatment of the exceptions is necessary. Tested by checking crashing programs which otherwise work in or1ksim.

The OpenRISC architecture does not have its own move register instruction. Instead it uses either "l.addi rd, r0, x" or "l.ori rd, rs, 0" or "l.or rd, rx, r0" The l.ori instruction is automatically optimized but not the l.addi instruction. This patch optimizes for this special case. Signed-off-by: NSebastian Macke <sebastian@macke.de> Reviewed-by: NJia Liu <proljc@gmail.com> Signed-off-by: NJia Liu <proljc@gmail.com>

The madvise for zeroed out pages was introduced when every transferred zero page was memset to zero and thus allocated. Since commit 211ea740 we check for zeroness of a target page before we memset it to zero. Additionally we memmap target memory so it is essentially zero initialized (except for e.g. option roms and bios which are loaded into target memory although they shouldn't). It was reported recently that this madvise causes a performance degradation in some situations. As the madvise should only be called rarely and if it's called it is likely on a busy page (it was non-zero and changed to zero during migration) drop it completely.

This avoids each test needing to add it to suppress windows popping up. [Commit 7ceeedd0 ("blockdev-test: add test case for drive_add duplicate IDs") and commit 43cd2098 ("qdev-monitor-test: add device_add leak test cases") added qtest tests without specifying -display none. As a result, "make check" now tries to use graphics (GTK or SDL). Since graphics are not used by the test and inappropriate for headless "make check" runs, add the missing -display none.

Since the move away from the global areg0, we're no longer globally reserving areg0. Which means our use of R7 clobbers a call-saved register. Shift areg0 into the windowed registers. Indeed, choose the incoming parameter register that it comes to us by. This requires moving the register holding the return address elsewhere. Choose R33 for tidiness.

There was a misconception that a stop bit is required between a compare and the branch that uses the predicate set by the compare. This lead to the usage of an extra bundle in which to perform the compare. The extra bundle left room for constants to be loaded for use with the compare insn. If we pack the compare and the branch together in the same bundle, then there's no longer any room for non-zero constants. At which point we can eliminate half the function by not handling them.

For now guest agent uses following command to shutdown system: shutdown -P +0 "blabla" but this syntax works only with shutdown command from systemd or upstart, because SysV shutdown requires -h switch. Following patch changes the command so it works with systemd, upstart and SysV With upstart/systemd qga use one of thee commands, depending on 'mode' parameter: shutdown -P +0 "..." shutdown -H +0 "..." shutdown -r +0 "..." SysV equivalents for these are: shutdown -h -P +0 "..." shutdown -h -H +0 "..." shutdown -h -r +0 "..." and these retain their meaning with upstart/systemd. According to FreeBSD manpages, shutdown does not accept -P and -H options. Commands should be: shutdown -p +0 "..." shutdown -h +0 "..." shutdown -r +0 "..." shutdown in Solaris does not accept any of -hHpPr and does not accept time in "+0" format Signed-off-by: NMichael Avdienko <whitearchey@gmail.com> Signed-off-by: NMichael Tokarev <mjt@tls.msk.ru>

This patch moves ret assignment after reporting original error. We were lucky to pass qemu-iotests 048 (qemu-img compare case) but when I tried to run with TEST_DIR=/tmp (tmpfs), it fails with a "wrong" mismatch offset. This fixes two bugs. In the first if branch, setting ret to 1 before using it makes dead code in the next line: pnum is never added to mismatch offset even if ret was 0. In the other if branch, currently the output error is always -4: strerror(-4) -> Unknown error -4 Added regression test in case 048.

if multiple sectors spanning multiple clusters are read the function count_contiguous_clusters should ensure that the cluster type should not change between the clusters. Especially the for-loop should break when we have one or more normal clusters followed by a compressed cluster. Unfortunately the wrong macro was used in the mask to compare the flags. This was discovered while debugging a data corruption issue when converting a compressed qcow2 image to raw. qemu-img reads 2MB chunks which span multiple clusters.
