The format is described in patches.ini.
For now it only supports the kips defined in hekate's code.
Next versions will add support for defining other kips.
Add a configuration option "Full w/ hashfile" to
the "verification" option menu, to enable hashfile
generation when doing full verification of a backup.
When enabled, during full backup verification we save the
chunk's SHA256 digest in a hashfile next to the output file
we're currently verifying.
The performance impact is negligible between "Full verify"
and "Full verify w/ hashfile", because we already
compute the SHA256 of the chunks when verifying.
We save the SHA256 per chunks (4 MB) because due to
SE limitations, we can't compute the SHA256 of the
whole partition (or rawnand).
On the other hand a pure software implementation
is way too slow to be bearable, even asm-optimized:
between 15 and 90 seconds per 4 MB chunk for
crc32/sha1/sha256, depending on the optimizations
and the actual algorithm.
The output hash file format is as follows:
# chunksize: <CHUNKSIZE_IN_BYTES>
sha256_of_chunk_1
sha256_of_chunk_2
...
sha256_of_chunk_N
Some Sandisk U1 sd cards do not behave nicely if they power cycle too fast. A min 100ms wait, is enough to mitigate that.
Fortunately, because of how the code paths are structured, this was never hit.
[Stock]
fss0={sd path}
stock=1
Can now work for both older and new HOS versions.
- <= 6.2.0 loads nothing and removes kernel patching.
- >= 7.0.0 loads exo, wb and removes kernel patching.
This requires that fss0 {sd path} is valid. Otherwise it will fail on ini cfg parsing.
If <= 6.2.0 and no FSS0
[Stock]
stock=1
will provide a cleaner stock with no kernel patching.
Using "fss0={sd path}" allows you to parse kips, exosphere and warmboot from a fusee secondary binary.
Exosphere and warmboot are overridable if these entries are defined after that.
Additionally any extra kip can be loaded as before via
kip1={sd path}/* for many
or
kip1={sd path} for a sigle one
Warning: Don't double load core kips like loader, pm, sm and ams_mitm. The result will be a hang.
This is important, otherwise it can break tools like memloader.
Until a semi-usb init solution is found, hekate will show bootlogo and allow you to go to menu.
If >= 7.0.0 after that, it will run sept and then show logo again without a wait. For as long as rebuilding the boot process takes.
- Use always aligned buffers to up the speed for DMA usage. For verification, backup and restore.
- Rework verification a little bit and make default Sparse mode.
Sparse mode protects from fake sd cards, bad sectors and frequent I/O corruption. Aka, ~100% of cases.
