Implement qcow2 support, convert most images from raw This allows exbibyte-sized images, compression and (potentially) non-destructive writing. 2023-01-05 06:20:40 +01:00			`Copyright (C) 2020-2023 Ivan Baravy <dunkaist@gmail.com>`

Split vdisk to vdisk_raw and vdisk_qcow2 vdisk_raw got existing functionality, no new features. Qcow2 support is yet to be implemented. Miniz was imported with that in mind. 2023-01-04 01:15:40 +01:00			`struct vdisk {`

Create platform specific I/O module, prepare for io_uring 2023-01-16 05:54:34 +01:00			`int adjust_cache_size;`
Implement vnet_null device Such device don't need new threads and files but are valid ethernet devices for the kernel. Convenient for testing. 2023-02-06 17:01:37 +01:00			`const void *io;`

Coverage collection speed up 4x! Also, adjust disk cache size and move set_eflags_tf() to trace_lbr.c. 2020-02-21 03:21:09 +01:00
