According to RFC 1350 and RFC 2347, TFTP server should answer RRQ by either OACK or DATA packet. Qemu's internal TFTP server answers RRQ with additional options by sending both OACK and DATA packet, thus breaking the "lock-step" feature of the protocol, and also confuses client. Proposed solution would be to, in case of OACK packet, wait for ACK from client and just then start sending data. Attached patch implements this.

Commit 3a03bfa5 added a fallback in case the Linux kernel running qemu is older than the kernel of the build system. Unfortunately, v1 was committed instead of v2, so the code has a bug that was revealed in the review (checking for the wrong error code).

This adds a rebase subcommand to qemu-img which allows to change the backing file of an image. In default mode, both the current and the new backing file need to exist, and after the rebase, the COW image is guaranteed to have the same guest visible content as before. To achieve this, old and new backing file are compared and, if necessary, data is copied from the old backing file into the COW image. With -u an unsafe mode is enabled that doesn't require the backing files to exist. It merely changes the backing file reference in the COW image. This is useful for renaming or moving the backing file. The user is responsible to make sure that the new backing file has no changes compared to the old one, or corruption may occur.

If an image references a backing file that doesn't exist, qemu-img info fails to open this image. Exactly in this case the info would be valuable, though: the user might want to find out which file is missing. This patch introduces a BDRV_O_NO_BACKING flag to ignore the backing file when opening the image. qemu-img info is the first user and provides info now even if the backing file is invalid.

After the next commit, pkg-config could be used for the shared library configuration case and sdl-config for static libraries. So I prepare the test here by doing two changes: at the same time I remove useless backslashes from the invocation of grep; 1) fixing a typo ($sd_cflags). The typo has been there since commit 1ac88f28 (remove sdl_static. Just do the right thing if static is yes, 2009-07-27). 2) fixing an erroneous "test `... | grep > /dev/null`" idiom that would never succeed since grep's output would be empty; 3) checking the status code after executing sdl-config --static --libs; this is needed for the next patch only.

Use new way to associate ROM files to devices. Currently, there is only a ROM file for i82559er included in QEMU, so the patch does not add .romfile for the other devices. When flexible mode is fixed in eepro100, adding more ROM files will be possible. It should be possible to create them from pxe-i82559er.bin, because etherboot uses the same driver for all eepro100 devices (only PCI ids differ). Maybe it is even possible to create a single pxe-i8255x.bin which supports all eepro100 devices (not supported with current etherboot).

The {div,divu}2 opcodes are intended for systems for which the division instruction produces both quotient and remainder. Sparc is not such a system. Indeed, the remainder must be computed as quot = a / b rem = a - (quot * b) Split out a tcg_out_div32 function that properly initializes Y with the extension of the input to 64-bits. Discard the code that used the 64-bit DIVX on sparc9/sparcv8plus without extending the inputs to 64-bits. Implement remainders in terms of division followed by multiplication.
