Virgil Dupras	1bcceb949c	blockdev: add Tell and fix blkGetCW ... Calling on blkGetC repeatedly was somehow very unstable and often failed. I didn't pinpoint exactly why, but keeping the call addr around and calling that instead seems like a better idea anyway.	2019-04-22 17:15:59 -04:00
Virgil Dupras	b4694225c5	blockdev: change GetC API ... Instead of waiting, GetC always return immediately, with Z indicating if something was fetched. The "wait" loop is implemented by the called (and in the new `blkGetCW`). This simplifies out-of-bounds verifications for storage blockdevs.	2019-04-22 14:26:16 -04:00
Virgil Dupras	a27da6f41a	add mmap part ... This also introduces the "seek" shell command.	2019-04-16 08:36:26 -04:00
