- Implemented sector size handling in the ATA disk emulation. This feature
still needs BIOS support to boot from a disk with big sectors.
- Enabled sector size support in the redolog_t class based disk image mode.
The base class can handle 512 byte blocks only, but that doesn't matter since
all valid sector sizes are multiple of it. So for now the growing, undoable
and volatile disk image modes internally read/write 512 bytes per call.
- TODO: BIOS, bximage.
- rewrite of the logical sector handling code to make seek latency support possible
- implemented variable HD seek latency for seek and read commands
- TODO #1: CD-ROM seek command returns status immediately, but it clears the DSC bit
and sets it at completion. Device should not accept ATAPI commands until DSC is set.
- TODO #2: clean up the seek latency code
- now using the more accurate name "seek latency"
- fixed CD-ROM LBA address range checks and renamed limit to "max_lba"
- make the latency for CD-ROM access variable depending on the distance between
current and new block address, Maximum value should only occur at first access
or after media change.
- TODO: make hard disk seek timing variable, too.
- still TODO: seek latency for USB drives (requires asynchronus packet support).
- use #if BX_SUPPORT_CDROM instead of #ifdef LOWLEVEL_CDROM
- devices with cdrom support now use the base class cdrom_base_c
- cdrom count variable moved to cdrom.cc
- cdrom_misc.cc: don't use ioctl's for ISO files
existing "iolight timer" code in the hard drive code. If an LED is registered
with the "auto-off" flag, the device only needs to turn on the LED to indicate
data transfer. The LED timer in the gui code turns it off after 0.5 seconds if
it is not actived by another transfer. Added this feature to all network
devices.
- TODO #1: implement this feature in the USB host controllers
- TODO #2: the unused timer in the hard drive code could be used for the
emulation of seek functions
parameters (path + status) have been set. TODO: implement this feature for the floppy, too.
- call update_drive_status_buttons() from update_runtime_options() to reduce the number of calls.
Now call update_runtime_options() from the gui floppy / cdrom handlers after closing dialog.
* moved runtime handlers for cdrom from config.cc to the device object
* cd media status variable is now always of type bx_bool
* changed obsolete gui names like "cdromD" to "cdrom1"
* TODO: implement new runtime config mechanism similar to USB
- HDIMAGE_HAS_GEOMETRY flag added to vmware3 & vmware4 modes (these modes use
the CHS values from image file)
- harddrv: renamed pointer to hdimage object
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
- 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
* ports for error register, sector count and sector number are shared between
both drives
* status register always returns the values of the selected drive (0x00 if
not present
* set correct signature for both drives in case of reset
- read raw toc for image files and platforms other than Windows XP implemented (ported from qemu)
- several cdrom capacity fixes / report capacity only on Bochs init and cdrom change
- flag 'using_file' must be set to 0 for WIN32 ASPI or direct access
- multisession format handling removed from harddrv.cc (now handled in cdrom code)
- ATAPI error messages improved
- prepared ATAPI buffer for block size 2352
- sense code ASC_ILLEGAL_OPCODE added for unimplemented/unknown ATAPI commands
- some panics changed to errors
- unsupported bits message in drive and head register changed to BX_DEBUG
- improved info about not existing drive
- indent mode fixed in ATAPI packet command section
images created with bximage (heads = 16, sectors per track = 63)
- size check for 'flat' hard disk images added. The image size is now compared
with the size calculated from the geometry.
- report the cdrom capacity in megabytes instead of bytes
- don't flood the logfile with error messages when the guest OS checks the cdrom
unit periodicly for media presence
