2010-08-26Sparc: update OpenBIOS images to r859Blue Swirl3-1/+1
Update Sparc32 and Sparc64 OpenBIOS images to SVN revision 859. Bring also pc-bios/README up to date including the update performed by 419ef5f1c6a9614e8ddcb0b0f826de692e7e4a43. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-08-26ppc4xx: load Bamboo kernel, initrd, and fdt at fixed addressesHollis Blanchard1-21/+18
We can't use the return value of load_uimage() for the kernel because it can't account for BSS size, and the PowerPC kernel does not relocate blobs before zeroing BSS. Instead, we now load at the fixed addresses chosen by u-boot (the normal firmware for the board). Signed-off-by: Hollis Blanchard <hollis@penguinppc.org>
2010-08-26ppc4xx: don't unregister RAM at resetHollis Blanchard1-1/+0
The PowerPC 4xx SDRAM controller emulation unregisters RAM in its reset callback. However, qemu_system_reset() is now called at initialization time, so all RAM is unregistered before starting the guest (!). Signed-off-by: Hollis Blanchard <hollis@penguinppc.org>
2010-08-26ppc4xx: correct SDRAM controller warning message conditionHollis Blanchard1-1/+1
The message "Truncating memory to %d MiB to fit SDRAM controller limits" should be displayed only when a user chooses an amount of RAM which can't be represented by the PPC 4xx SDRAM controller (e.g. 129MB, which would only be valid if the controller supports a bank size of 1MB). Signed-off-by: Hollis Blanchard <hollis@penguinppc.org>
2010-08-26Fix "make install" with a cross toolchainHollis Blanchard2-2/+7
We must be able to use a non-native strip executable, but not all versions of 'install' support the --strip-program option (e.g. OpenBSD). Accordingly, we can't use 'install -s', and we must run strip separately. Signed-off-by: Hollis Blanchard <hollis@penguinppc.org> Cc: blauwirbel@gmail.com

2010-08-26PPC: Add PV hypercall transport through fw_cfgAlexander Graf5-0/+50
On KVM for PPC we need to tell the guest which instructions to use when doing a hypercall. The clean way to do this is to go through an ioctl from userspace and passing it on to the guest using the device tree. So let's do the qemu part here: read out the hypercall and pass it on to the guest's fw_cfg so openBIOS can read it out and expose it again. Signed-off-by: Alexander Graf <agraf@suse.de>
2010-08-24Rearrange block headersBlue Swirl47-13/+51

2010-08-22VGA: Don't register deprecated VBE rangeAlex Williamson1-7/+0
Old versions of the BOCHs VGA BIOS (cira 2003) made use of VBE registers at 0xff80/81. In VBE API version 0xb0c2 these were moved to 0x1ce/cf. Unfortunately, QEMU still registers handlers for the old range. If a guest attempts to assign an I/O device overlapping this region, QEMU exits with a hw_error. Windows guests seem to like to assign I/O devices to the high end of the address space, so it's pretty easy to hot add an rtl8139 to a Win2k8 guest and trigger the bug. I can't find any reason to register these handlers, so let's remove the cruft. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-08-22pckbd: support for commands 0xf0-0xff: Pulse output bitBernhard Kohl1-3/+20
I have a guest OS which sends the command 0xfd to the keyboard controller during initialization. To get rid of the message "qemu: unsupported keyboard cmd=0x%02x\n" I added support for the pulse output bit commands. I found the following explanation here: http://www.win.tue.nl/~aeb/linux/kbd/scancodes-11.html#ss11.3 Command 0xf0-0xff: Pulse output bit Bits 3-0 of the output port P2 of the keyboard controller may be pulsed low for approximately 6 µseconds. Bits 3-0 of this command specify the output port bits to be pulsed. 0: Bit should be pulsed. 1: Bit should not be modified. The only useful version of this command is Command 0xfe. (For MCA, replace 3-0 by 1-0 in the above.) Command 0xfe: System reset Pulse bit 0 of the output port P2 of the keyboard controller. This will reset the CPU.

2010-08-19QEMUFileBuffered: indicate that we're ready when the underlying file is readyAvi Kivity1-0/+8
QEMUFileBuffered stops writing when the underlying QEMUFile is not ready, and tells its producer so. However, when the underlying QEMUFile becomes ready, it neglects to pass that information along, resulting in stoppage of all data until the next tick (a tenths of a second). Usually this doesn't matter, because most QEMUFiles used with QEMUFileBuffered are almost always ready, but in the case of exec: migration this is not true, due to the small pipe buffers used to connect to the target process. The result is very slow migration. Fix by detecting the readiness notification and propagating it. The detection is a little ugly since QEMUFile overloads put_buffer() to send it, but that's the suject for a different patch.

2010-08-15sparc escc IUS improvements (SunOS 4.1.4 fix)Artyom Tarasenko1-26/+30
According to scc_escc_um.pdf: - Reset Highest IUS must update irq status to allow processing of the next priority interrupt. - rx interrupt has always higher priority than tx on same channel The documentation only explicitly says that Reset Highest IUS command (0x38) clears IUS bits, not that it clears the corresponding interrupt too, so don't clear interrupts on this command.

2010-08-15win32: Avoid compiler warning (WIN32_LEAN_AND_MEAN redefined)Stefan Weil1-0/+4
configure adds the macro WIN32_LEAN_AND_MEAN to QEMU_CFLAGS, and SDL_syswm.h defines it, too. This results in a compiler warning (redefinition of WIN32_LEAN_AND_MEAN in SDL_syswm.h. That warning prevents compilations for win32 with warning = error). Fix this by removing the definition of WIN32_LEAN_AND_MEAN before including SDL_syswm.h.
