- Add a special list to the MSD state and add pointers to the runtime-only
options for the cdrom. The restore handler of this list calls runtime_config()
to make sure the media path and status are correctly updated.
- Registering a runtime config handler for the USB cdrom is not necessary since
runtime_config() is always called from the hub it is connected to.
- Restore a string parameter value only if it's different from the initial one.
with devices conected at runtime.
- Added restore handler support for the bx_list_c class. If a handler is
registered, it will be called after restoring all of the list's members.
- USB hub: add special lists to the port state and add pointers to the
runtime-only options for each port. The restore handler of this list calls
init_device() to make sure all connected devices can be restored.
- Call restore_logopts() after restoring hardware to make sure all saved
modules have been created.
- TODO: the USB cdrom also needs a fix for it's runtime-only options.
- 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.
- 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.
- 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.
- 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.
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.
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.
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.
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
