2009-10-27net: add macaddr type.Gerd Hoffmann
Add new type for mac addresses. Add function which sets the qemu default mac address if it finds the mac address uninitialized (i.e. all zeros). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-27Send a RARP packet after migration.Nolan
Currently, after a migration qemu sends a broadcast packet to update switches' MAC->port mappings. Unfortunately, it picks a random (constant) ethertype and crosses its fingers that no one else is using it. This patch causes it to send a RARP packet instead. RARP was chosen for 2 reasons. One, it is always harmless, and will continue to be so even as new ethertypes are allocated. Two, it is what VMware ESX sends, so people who write filtering rules for switches already know about it. I also changed the code to send SELF_ANNOUNCE_ROUNDS packets, instead of SELF_ANNOUNCE_ROUNDS + 1, and added a simple backoff scheme.

2009-10-27raw/linux-aio: Also initialize POSIX AIOKevin Wolf
When using Linux AIO raw still falls back to POSIX AIO sometimes, so we should initialize it. Not initializing it happens to work if POSIX AIO is used by another drive, or if the format is not specified (probing the format uses POSIX AIO) or by pure luck (e.g. it doesn't seem to happen any more with qcow2 since we have re-added synchronous qcow2 functions).

2009-10-27qcow2: Fix grow_refcount_table error handlingKevin Wolf
In case of failure, we haven't increased the refcount for the newly allocated cluster yet. Therefore we must not free the cluster or its refcount will become negative (and endless recursion is possible).

2009-10-27usb-linux: return USB_RET_STALL on -EPIPEPaul Bolle
0) This is an attempt to get an issue in usb-linux.c, for which a patch was posted about a year ago, finally fixed. 1) Mark Burkley submitted a "EHCI emulation module" for review in in October 2008 (see: http://lists.gnu.org/archive/html/qemu-devel/2008-10/msg01326.html). No EHCI emulation module was ever committed to qemu. 2) Part of that (large) patch was a fix for a separate issue in usb-linux.c. Max Krasnyansky has ACK'ed that fix (see: http://lists.gnu.org/archive/html/qemu-devel/2008-11/msg00032.html). 3) I already asked whether this fix was ready to be committed in last April (see: http://lists.gnu.org/archive/html/qemu-devel/2009-04/msg01763.html) 4) Maybe submitting this fix as a separate patch (with a really long commit message but without a Signed-off-by) and cc-ing everbody involved will help if actually getting this issue fixed.

2009-10-27eepro100: Restructure codeStefan Weil
This patch only moves about 150 lines of code from function eepro100_cu_command to a new function action_command. A goto statement was replaced by a for loop. There are no functional changes. Nor did I change comments starting with // (they will be removed by future patches). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-10-27target-arm: fix neon shift helper functionsJuha Riihimäki
Current code is broken at least on recent compilers, comparison between signed and unsigned types yield incorrect code and render the neon shift helper functions defunct. This is the third revision of this patch, casting all comparisons with the sizeof operator to signed ssize_t type to force comparisons to be between signed integral types.

2009-10-27target-arm: fix neon vsri, vshl and vsli opsJuha Riihimäki
Shift by immediate value is incorrectly overwritten by a temporary variable in the processing of NEON vsri, vshl and vsli instructions. This patch has been revised to also include a fix for the special case where the code would previously try to shift an integer value over 31 bits left/right.

2009-10-27target-arm: allow modifying vfp fpexc en bit onlyJuha Riihimäki
All other bits except for the EN in the VFP FPEXC register are defined as subarchitecture specific and real functionality for any of the other bits has not been implemented in QEMU. However, current code allows modifying all bits in the VFP FPEXC register leading to problems when guest code is writing 1's to the subarchitecture specific bits and checking whether the bits stay up to verify the existence of functionality which in fact does not exist in QEMU. This patch has been revised to include the same behavior change in the gdb register write function.

Add support for NEON vld1.64 and vst1.64 instructions. This patch is revised to follow more closely the specification and raises undefined exception if 64bit element size is used for vld2/vst2 or vld4/vst4 instructions.

2009-10-27target-arm: fix neon vshrn/vrshrn opsJuha Riihimäki
In the existing code shift value is clobbered during the pass loop. This patch changes the code so that it stores the intermediate result in the target neon register directly and eliminates the need to use a temporary to hold the intermediate value thus leaving the shift value in the temporary variable intact. This is a new patch in this version of the patch series.

2009-10-23target-i386: implement lzcnt emulationAndre Przywara
lzcnt is a AMD Phenom/Barcelona added instruction returning the number of leading zero bits in a word. As this is similar to the "bsr" instruction, reuse the existing code. There need to be some more changes, though, as lzcnt always returns a valid value (in opposite to bsr, which has a special case when the operand is 0). lzcnt is guarded by the ABM CPUID bit (Fn8000_0001:ECX_5).
