2013-06-17tcg-ppc64: bswap64 rotates output 32 bitsAnton Blanchard1-2/+0
If our input and output is in the same register, bswap64 tries to undo a rotate of the input. This just ends up rotating the output. Cc: qemu-stable@nongnu.org Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-06-17tcg-ppc64: Fix RLDCL opcodeAnton Blanchard1-5/+6
The rldcl instruction doesn't have an sh field, so the minor opcode is shifted 1 bit. We were using the XO30 macro which shifted the minor opcode 2 bits. Remove XO30 and add MD30 and MDS30 macros which match the Power ISA categories.

2013-06-17NVMe: Initial commit for new storage interfaceKeith Busch6-0/+1604
Initial commit for emulated Non-Volatile-Memory Express (NVMe) pci storage device. NVMe is an open, industry driven storage specification defining an optimized register and command set designed to deliver the full capabilities of non-volatile memory on PCIe SSDs. Further information may be found on the organizations website at: http://www.nvmexpress.org/ This commit implements the minimum from the specification to work with existing drivers.

2013-06-17sheepdog: support 'qemu-img snapshot -a'Liu Yuan1-7/+5
Just call sd_create_branch() in the snapshot_goto to rollback the image is good enough. With this patch, 'loadvm' process for sheepdog is modified: Suppose we have a snapshot chain A --> B --> C, we do 'loadvm A' so as to get a new chain, A --> B | V C1 in the old code: 1 reload inode of A (in snapshot_goto) 2 read vmstate via A's vdi_id (loadvm_state) 3 delete C and create C1, reload inode of C1 (sd_create_branch on write) with this patch applied: 1 reload inode of A, delete C and create C1 (in snapshot_goto) 2 read vmstate via C1's parent, that is A's vdi_id (loadvm_state) This will fix the possible bug that QEMU exit between 2 and 3 in the old code Cc: qemu-devel@nongnu.org Cc: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Cc: Kevin Wolf <kwolf@redhat.com> Cc: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Liu Yuan <namei.unix@gmail.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

Commit 047d4e151dd46 "Unbreak -no-quit for GTK, validate SDL options" broke build of qemu without sdl, by referencing `no_frame' variable which is defined inside #if SDL block. Fix that by defining that variable unconditionally. This is a better fix for the build issue introduced by that patch than a revert. This change keeps the new functinality introduced by that patch and just fixes the compilation. It still is not a complete fix around the original issue (not working -no-frame et al with -display gtk), because it makes only the legacy interface working, not the new suboption interface, so a few more changes are needed.

2013-06-14ide-test: fix failure for test_flushMichael Roth1-1/+4
bd07684aacfb61668ae2c25b7dd00b64f3d7c7f3 added a test to ensure BSY flag is set when a flush request is in flight. It does this by setting a blkdebug breakpoint on flush_to_os before issuing a CMD_FLUSH_CACHE. It then resumes CMD_FLUSH_CACHE operation and checks that BSY is unset. The actual unsetting of BSY does not occur until ide_flush_cb gets called in a bh, however, so in some cases this check will race with the actual completion. Fix this by polling the ide status register until BSY flag gets unset before we do our final sanity checks. According to f68ec8379e88502b4841a110c070e9b118d3151c this is in line with how a guest would determine whether or not the device is still busy.

2013-06-14configure: dtc: Probe for libfdt_env.hPeter Crosthwaite2-36/+2
Currently QEMU provides a local clone of the file libfdt_env.h in /include. This file is supposed to come with the libfdt package and is only needed for broken installs of libfdt. Now that we have submodule dtc, just ignore these broken installs and prompt for the dtc submodule install instead. QEMU's local libfdt_env.h is removed accordingly. Manifests as a bug when building QEMU with modern libfdt. The new version of libfdt does not compile when QEMUs libfdt_env.h takes precedence over the hosts.
