* cut model string on boot screen if larger than 36 characters to make one
"ata" message fit in one line
* config parameter for model string needs one more byte
* harddrive: terminate model string with null
* don't panic if byte count is zero in PACKET-DMA mode (the specs say that
byte count is used for PIO modes. The behaviour in DMA mode is not
mentioned, but seems to be ignored in that case.)
* pci_ide: initialize sector size with the BM-DMA byte count (disk read
commands will overwrite this value, some ATAPI commands are using the
original one.)
* non-disk-read ATAPI commands simply copy the buffer in DMA mode
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
a Bochs session unless the configuration (transfer mode) changes. Then the
"drive id" data is simply copied to the output buffer.
- removed unused "drive id" example (Conner CFA540A)
- added stubs for the ATA flush cache commands
- converted some tabs to spaces
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
unregister_irq(). This is required since there are some devices that don't
use a string constant for the handler name.
- replaced true / false by portable 0 / 1 values.
(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
not when reading the error register
- the DSC status bit is not cleared in case of an error
- a not existing drive does not set the ERR status bit and the error register
- all messages related to correctly aborted commands on non-disk devices changed
to type BX_INFO
- some other log message output cleanups
- ATA command 'set multiple mode' fixed (missing interrupt and value check)
- hard disk sector read/write rewritten and simplified
- hard disk now reporting ATA-3 supported
- updated drive buffer size for save/restore
read/write commands)
- prepared i/o buffer for multi sector transfers
- power management commands "standby now" and "idle immediate" now returning success
- store size of virtual disk in sparse header to simplify geometry detection/check
- enabling geometry autodetection causes a panic if not supported by image
- simplified geometry detection code
- unsupported ATAPI commands now cause a BX_DEBUG message and no addtional
error code info (avoid flooding log file)
- a bunch of image size handling changes
* 'hd_size' contains the size of the virtual hard disk (for geometry check/detection)
* passing the size calculated from the geometry not needed in some cases
- indent mode changes
