2010-06-29lsi53c895a: fix Phase Mismatch JumpPaolo Bonzini
lsi_bad_phase has a bug in the choice of pmjad1/pmjad2. This does not matter with Linux guests because it uses just one routine for both, but it breaks Windows 64-bit guests. This is the text from the spec: "[The PMJCTL] bit controls which decision mechanism is used when jumping on phase mismatch. When this bit is cleared the LSI53C895A will use Phase Mismatch Jump Address 1 (PMJAD1) when the WSR bit is cleared and Phase Mismatch Jump Address 2 (PMJAD2) when the WSR bit is set. When this bit is set the LSI53C895A will use jump address one (PMJAD1) on data out (data out, command, message out) transfers and jump address two (PMJAD2) on data in (data in, status, message in) transfers." Which means: CCNTL0.PMJCTL 0 SCNTL2.WSR = 0 PMJAD1 0 SCNTL2.WSR = 1 PMJAD2 1 out PMJAD1 1 in PMJAD2 In qemu, what you get instead is: CCNTL0.PMJCTL 0 out PMJAD1 0 in PMJAD2 <<<<< 1 out PMJAD1 1 in PMJAD1 <<<<< Considering that qemu always has SCNTL2.WSR cleared, the two marked cases (corresponding to phase mismatch on input) are always jumping to the wrong PMJAD register. The patch implements the correct semantics. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-06-28fix CPUID vendor overrideAndre Przywara
the meaning of vendor_override is actually the opposite of how it is currently used :-( Fix it to allow KVM to export the non-native CPUID vendor if explicitly requested by the user. The intended behavior is: With TCG: - always inject the configured vendor (either hard-coded, in config files or via ",vendor=" commandline) With KVM: - by default inject the host's vendor - if the user specifies ",vendor=" on the commandline, use this instead of the host's vendor - all pre-configured vendors (hard-coded, config file) are ignored Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2010-06-27win32: Add missing function ffsStefan Weil
mingw32 does not include function ffs. Commit c6d29ad6e24533cc3762e1d654275607e1d03058 added a declaration for ffs, but an implementation was missing. For compilations with optimization, the compiler creates inline code, so the implementation is not always needed.

2010-06-27mask all interrupts when MASTER_DISABLE is setArtyom Tarasenko
The MASTER_DISABLE bit (aka mask-all) masks all the interrupts. According to Sun-4M System Architecture "The level–15 interrupt sources [...] are maskable with the Interrupt Target Mask Register. While these interrupts are considered ’non–maskable’ within the SPARC IU, a mask capability is provided to allow the boot firmware to establish a basic environment before receiving any level–15 interrupts, which are non–maskable within SPARC. A mask–all bit is provided to allow disabling of all external interrupts during change of the CIT."

Mapped mode stores extended attributes in the user space of the extended attributes. Given that the user space extended attributes are available to regular files only, special files are created as regular files on the fileserver and appropriate mode bits are added to the extended attributes.

Mapped mode stores extended attributes in the user space of the extended attributes. Given that the user space extended attributes are available to regular files only, special files are created as regular files on the fileserver and appropriate mode bits are added to the extended attributes. This method presents all special files and symlinks as regular files on the fileserver while they are represented as special files on the guest mount. Implemntation of symlink in mapped security model: A regular file is created and the link target is written to it. readlink() reads it back from the file.

In the mapped security model, VirtFS server intercepts and maps the file object create and get/set attribute requests. Files on the fileserver will be created with VirtFS servers (QEMU) user credentials and the client-users credentials are stored in extended attributes. On the request to get attributes, server extracts the client-users credentials from extended attributes and sends them to the client.

2010-06-22give some useful error messages when tap openMichael Tokarev
In net/tap-linux.c, when manipulation of /dev/net/tun fails, it prints (with fprintf) something like this: warning: could not open /dev/net/tun: no virtual network emulation this has 2 issues: 1) it is not a warning really, it's a fatal error (kvm exits after that), 2) there's no indication as of what's actually wrong: printing errno there is helpful. The patch below removes the "warning" prefix, uses %m (since it's linux, %m is available as format modifier), and changes fprintf() to %qemu_error(). Now it prints something like this instead: could not configure /dev/net/tun: Device or resource busy (there are 2 messages like that in the same function) This fixes Debian bug #578154, see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=578154 Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
