This reverts commit 4839abe7. The commit was badly broken, Gentoo has sdl as the default driver, consequently 5 gentoo users have hit the breakage and were kind enough to report, so thank you: Claes Gyllenswrd vekin Chris But above all thanks to Toralf Foerster who actually provied enough information to pinpoint the breakage to sdlaudio. http://bugs.gentoo.org/show_bug.cgi?id=294269

Don't clear interrupts on disabling, because * Sun4M_SystemArchitecture_edited2.pdf doesn't describe that masking or un-masking IRQ shall clear pending ones. * Field tests also show that SPARCstation-20 doesn't clear them. * The patch makes Solaris 2.5.1/2.6 boot ~1500 times faster (~20 seconds instead of ~8 hours) Signed-off-by: NArtyom Tarasenko <atar4qemu@gmail.com> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

According to pages 9-31 - 9-34 of "SuperSPARC & MultiCache Controller User's Manual": 1. "A lower priority fault may not overwrite the MFSR status of a higher priority fault." 2. The MFAR is overwritten according to the policy defined for the MFSR 3. The overwrite bit is asserted if the fault status register (MFSR) has been written more than once by faults of the same class 4. SuperSPARC will never place instruction fault addresses in the MFAR. Implementation of points 1-3 allows booting Solaris 2.6 and 2.5.1. v2: CODING_STYLE fixes Signed-off-by: NArtyom Tarasenko <atar4qemu@gmail.com> Signed-off-by: NBlue Swirl <blauwirbel@gmail.com>

The existing P_REXB internal opcode flag unconditionally emits the REX prefix. Technically it's not needed if the register in question is %al, %bl, %cl, %dl. Eliding the prefix requires splitting the P_REXB flag into two, in order to indicate whether the byte register in question is in the REG or the R/M field. Within TCG, the byte register is in the REG field only for stores. Signed-off-by: NRichard Henderson <rth@twiddle.net> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

When make is called without a valid configuration, it should tell the user what to do. Revision 0e8c9214 was a regression which resulted in a message which was no longer user friendly (reported by Aurelien Jarno). This patch restores the old behaviour.

Attached is a patch to fix a typo in 'P' packet processing for M68K. Without this patch, QEMU fails to honor GDB's P packets from GDB (writing to registers) for the address registers (A0 - A7). The problem is because of an obvious typo. Notice that the second "if" condition is meant to be n < 16 in: if (n < 8) { : } else if (n < 8) { Signed-off-by: NKazu Hirata <kazu@codesourcery.com> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

This avoids an unnecessary REX.W prefix when dealing with AND operands that fit into a 32-bit quantity. The most common change actually seen is movz[wb]q -> movz[wb]l.

The stat64/fstat64 syscalls are broken for alpha linux-user. This is because Alpha, even though it is native 64-bits, has a stat64 syscall that is different than regular stat. This means that the "TARGET_LONG_BITS==64" check in syscall.c isn't enough. Below is a patch that fixes things for me, although it might not be the cleanest fix. This issue keeps sixtrack and fma3d spec2k benchmarks from running.

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.

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.
