* added support for memory above the PCI hole (Izik Eidus)
* smp_probe: instead of timimg out, wait until all cpus are up (Avi Kivity)
* Bochs BIOS changes to support HPET in Qemu (Beth Kon)
- added documentation about CMOS registers set by Qemu
Make save/restore default feature, the configure option for save/restore removed from configure script and save/restore made available forever. All code now assume it is exists. Bochs save/restore tree previosly called "save_restore" renamed to "bochs" tree and it will be havily used everywhere, starting from save/restore and ending by various bochs debugger functions. I am going to rework debugger code to get rid of debug CPU access functions and use this "bochs" param tree instead
done by the object destructor (changes in cmos, hard drive and keyboard)
- bx_unload_plugins() now deletes the devmodel object in non-plugin mode
- CMOS device now prints the time on exit in human-readable format
(TODO: find a way to call plugin_fini() for non-core devices if plugins are
disabled)
- set the device pointers back to stubs after unloading plugins
- added debug message "Exit" in all device plugin destructors
- clock/cmos menu added in textconfig and wx
- enum parameter type now supports new parameter handling
- long text format for numeric parameters added (useful when both textconfig and
wx are present)
- wx: handling of list flag USE_BOX_TITLE fixed
- textconfig: optional memory features moved to submenus
- siminterface generates a unique id for new parameters (used for wx dependencies)
- proposed parameter tree updated
- floppy options init code cleanup (still using old-style parameters)
- cmos image options renamed
- new cmos option controls the usage of the RTC values from image
- report time0 in use after handling the cmos image stuff
- MSVC warning fixed
- unsupported shutdown status values no longer cause a panic
- definition of BX_NUM_CMOS_REGS moved from config.h to cmos.h (TODO: get rid
of this and implement 128 registers)
- indent mode fixed in modified section
bochs.h already not include iodev.h which reduces compilation dependences for almost all cpu and fpu files, now cpu files will not be recompiled if iodev includes was changed
- pit: and time0: options are still supported but deprecated
- warn when parsing deprecated directives
- fix wrong number of ata_device_translation_names
- still to do:
- setting time0 to utc is not yet supported
- the man page, user guide and .bochsrc still need to be updated
with the new options
This is necessary for devices with different i/o port masks.
- BX_MAX_IO_DEVICES increased to 30
- io_len mask fixed and unnecessary io_len checks removed in
* biosdev.cc
* cmos.cc
* dma.cc
- implementation of the UIP bit using a new timer handler. The one_second_timer()
function only sets the UIP bit and starts the UIP timer. The uip_timer()
function handles the date / time update, the alarm check and finally clears
the UIP bit.
- writing to control register A doesn't change the UIP bit
register values to a new timeval after date/time change. There is only a
BX_ERROR for now.
- added separate cases for the alarm time registers and a BX_DEBUG message that
reports the new alarm time.
. read port 0x70 (cmos) : return index
. atapi function 46 and 4a : return error
- put back the log prefix for cmos that disappeared when we did the plugins
"bx_bool" which is always defined as Bit32u on all platforms. In Carbon
specific code, Boolean is still used because the Carbon header files
define it to unsigned char.
- this fixes bug [ 623152 ] MacOSX: Triple Exception Booting win95.
The bug was that some code in Bochs depends on Boolean to be a
32 bit value. (This should be fixed, but I don't know all the places
where it needs to be fixed yet.) Because Carbon defined Boolean as
an unsigned char, Bochs just followed along and used the unsigned char
definition to avoid compile problems. This exposed the dependency
on 32 bit Boolean on MacOS X only and led to major simulation problems,
that could only be reproduced and debugged on that platform.
- On the mailing list we debated whether to make all Booleans into "bool" or
our own type. I chose bx_bool for several reasons.
1. Unlike C++'s bool, we can guarantee that bx_bool is the same size on all
platforms, which makes it much less likely to have more platform-specific
simulation differences in the future. (I spent hours on a borrowed
MacOSX machine chasing bug 618388 before discovering that different sized
Booleans were the problem, and I don't want to repeat that.)
2. We still have at least one dependency on 32 bit Booleans which must be
fixed some time, but I don't want to risk introducing new bugs into the
simulation just before the 2.0 release.
