f789ee4ff0
Introduces a track to segment decoder.
...
This will be needed to make formats like G64 and HFE writeable, but probably also will be usable to speed up static analysis.

Introduces a new class hierarchy for disk images.

Increasing independence of format-specific stuff and generic caching without mangling them into a common namespace, and allowing in some cases for a decrease in read/write blocking.

Switches the CPC static analyser to maintaining a vector of pointers rather than a complete copy of files.
...
Hence saves a lot of copying and moving — around a second's worth when dealing with the selected test disk.

Devolves `TimedEventLoop` ownership from disk controllers to drives
2017-09-15 19:15:44 -04:00
662d031e3c
Adds exposition on the meaning of a disk controller being in write mode.
2017-09-15 19:14:36 -04:00
bf20c717fb
The Drive now no longer produces input when in writing mode — other than announcing the index hole.
2017-09-14 22:32:13 -04:00
4d4a0cf1d2
Puts the disk controller back into the loop with knowledge about reading mode, and uses that knowledge to cut off the PLL.

2017-09-11 22:08:10 -04:00
d3c385b471

Thereby returns working motor control to the CPC.

96bf133924
Withdraws requirement for DiskController users to specify a PLL multiplier or to provide rotation speed.
...
In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.
2017-09-10 22:56:05 -04:00
6d6cac429d
Fixes extra time accumulation during track running.
...
Introduces a bunch of further asserts, which aided me in determining the fix, i.e. that Drives being responsible for their own setup_track could double-pump the event loop.

Mostly lifted from DiskController. `set_disk_with_track` has been withdrawn in favour of providing a suitable wrapper `Disk` subclass, as being an unnecessary complexity and intermingling of concerns.
