823ba769fb Some work on the USB floppy emulation. 
- Removed USB device type handling from constructor and init code, since we
  only the 'floppy' type here.
- Write commands now using the device buffer for one sector.
TODO: support for starting without media and runtime media change.

5bc1717adc Removed the data tranfer limit for read/write commands. 
- The read buffer is now limited to 16 sectors and the read commands can fill
  it multiple times until all sectors have been read.
- The write commands are currently not using the device buffer, so no panic
  should happen here.

16fb8317bd Fixed parameter handler issues found with runtime changes while cdrom tray locked. 
- bx_param_num_c: set the value returned from the handler.
- bx_param_string_c: set the new value after processing the handler.
- harddrv param handler: check lock state of cdrom and modify value if true.

8a1e31ef08 Added common USB device option "debug" to turn on BX_DEBUG reporting at 
connection time.
Fixed USB floppy capacity entries for 1.44 MB (last LBA, not LBA count).

fa5353698d CMOS boot setup moved to the floppy init code to make Bochs BIOS boot work in 
case no harddrv plugin is loaded (no ata controller enabled). The floppy and
boot parameters are only set up if no CMOS image is enabled.

20aeed208b Fixed some panics when Bochs is used without the harddrv plugin (ata* disabled). 
TODO: Fix Bochs BIOS for that case (SeaBIOS is okay).

87d40fe673 Some work on the status LED support for removable devices. 
- Force a status bar update after unregistering an item.
- Added status indicators for USB disk and cdrom.
- Handle USB device disconnect in the runtime config handler, too.

3986a0b703 Extended status bar LED feature to support dynamic indicators for removable 
devices like USB disk, cdrom or floppy. Using this feature for the new USB
floppy. Removed static indicators for port activity from the USB HC code.
TODO: Implement status LEDs for USB disk and cdrom.

6161ffea73 Added initial version of UFI/CBI floppy disk storage device support written 
by Ben Lunt. To connect a USB floppy you can use the 'floppy' device with the
path to the image separated with a colon. VVFAT is also supported.
FIXME: The device detection fails on some recent Linux distributions.
FIXME: Only 1.44M media format is currently supported.
TODO: Media change without disconnect is not implemented yet.

ee6bfaa4c4 Added separate thread for the PCM data conversion. Only in case of dual output 
sendwavepacket() directly calls the conversion method and output(). In all other
cases it puts the unmodified data into a buffer and the conversion thread is
doing the main job and puts the data into the output buffer chain.
TODO: resampling could also be done by the new thread.

7be46cda6a Fixed SF bug #1376 (this change was missing in rev. 12473). 2015-05-25 12:33:39 +00:00

c43ea147bf ~1% emulation speedup by skipping pageWriteStamp check for stack writes. 
For now the optimization is supported only when no SMP is compiled in because it doesn't handle cross-modifying code.

The current stack page will cache also current pageWriteStamp for that page and could skip pageWriteStamp access if possible.
Any code fetch access missing trace cache will invalidate current stack page.
Code fetch accesses from another SMP threads should do the same to support SMP.

Next step:
 - support SMP
 - support pageWriteStamp access skipping for all other memory writes from all segments

f0d7379908 remove BxResolveModrm member in BxInstruction_c class and inline resolve functions into instruction handlers instead. helps to remove indirect branch mispredictions (suggested by Vtune). measured speedup on Win7-64 boot is 5%, on other guests it might vary between 1% and 5% 2015-05-16 20:29:49 +00:00
