2009-01-24Support epoch of 1980 in RTC emulation for MIPS Magnumaurel32
On the MIPS Magnum, the time that is held in the RTC's NVRAM should be relative to midnight on 1980-01-01. This patch adds an extra parameter to rtc_init(), allowing different epochs to be used. For the Magnum, 1980 is specified, and for all other machines, 2000 is specified. I've not modified the handling of the century byte, as with an epoch of 1980 and a year of 2009, one could argue that it should hold either 0, 1, 19 or 20. NT 3.50 on MIPS does not read the century byte.

2009-01-16G364 video adapter enhancementaurel32
This patch improves G364 video card emulation (used in MIPS Magnum machine): - Use memory dirty tracking to not refresh whole screen each time - Use macros for debugging messages - Add support for hardware cursor - Handle Y-panning - Raise irq at each screen redraw - Support retrieving of some registers - Add load/save support The emulation has been tested in Linux 2.1 and Windows NT 3.5, in 640x480, 800x600, 1024x768 and 1280x1024 resolutions.

2009-01-16graphical_console_init change (Stefano Stabellini)aliguori
Patch 5/7 This patch changes the graphical_console_init function to return an allocated DisplayState instead of a QEMUConsole. This patch contains just the graphical_console_init change and few other modifications mainly in console.c and vl.c. It was necessary to move the display frontends (e.g. sdl and vnc) initialization after machine->init in vl.c. This patch does *not* include any required changes to any device, these changes come with the following patches. Patch 6/7 This patch changes the QEMUMachine init functions not to take a DisplayState as an argument because is not needed any more; In few places the graphic hardware initialization function was called only if DisplayState was not NULL, now they are always called. Apart from these cases, the rest are all mechanical substitutions. Patch 7/7 This patch updates the graphic device code to use the new graphical_console_init function. As for the previous patch, in few places graphical_console_init was called only if DisplayState was not NULL, now it is always called. Apart from these cases, the rest are all mechanical substitutions.

2009-01-01target-mips: DMA support for RC4030 chipsetaurel32
Attached patch implements DMA support to RC4030 chipset and simplifies jazz IO part (at 0xf0000000), where registers contain 16 bit values. Config register has not a clear meaning (only one value is always valid, and sometimes another one), so use a magic value instead. The patch also wires DMA transfers for the SCSI adapter in the Jazz emulation (Mips Magnum 4000 and Acer Pica 61).

2008-12-10MIPS Magnum: fix memory-mapped i8042aurel32
Current implementation of memory-mapped i8042 controller is atm implemented with an interface shift (it_shift) parameter, like most all memory-mapped devices in Qemu. However, this isn't suitable for MIPS Magnum, where i8042 controller is at 0x80005000 up to 0x80005fff. Thomas Bogendoerfer (from #mipslinux) tested the behaviour of a real machine, and found that odd addresses are for status/command register, and even addresses for data register. Attached patch implements this behaviour by replacing the it_shift parameter by a mask one. Incidentally, keyboard now works on OpenBSD 2.3, which accesses i8042 controller at 0x80005060 and 0x80005061.

2008-10-07machine struct - specify max_cpus at the per machine level (Jes Sorensen)aliguori
Introduce a max_cpus per-machine variable, allowing individual boards to limit it's number of CPUs. Check requested number of CPUs in setup code and exit if it exceeds the supported number for the machine. This also renders the static MAX_CPUS check obsolete, so remove this from vl.c.
