I found some offsets (untested) for 7.02, maybe that's helpful to someone
#define syscall_offset 0x1c0
#define printf_offset 0x000BC730
#define kmem_alloc_offset 0x001170F0 (fixed to be same as mira)
#define kernel_map_offset 0x21c8ee0
Although i'm currently struggeling to compile everything (i.e. setting up cross compile toolchain on macOS).
Haven't looked up offsets for ps4-kexec 7.02 yet...
These ones are in upstream Mira already.
Here are some more (for ps4-kexec)
#define kern_off_snprintf 0xbca30
#define kern_off_copyinstr 0x2f6e0
#define kern_off_kmem_alloc_contig 0x430780 //unsure
#define kern_off_kmem_free 0x1172c0
#define kern_off_kernel_map 0x21c8ee0
#define kern_off_kern_reboot 0x2cd780
It's probably easier to "port" offsets from older kernel than trying to "map" freebsd sourcecode from github to the binary. Gonna see if i can find a 6.72 dump somewhere...
Also where i can find "upstream Mira offsets" so that i don't do twice the work?
Alright, found all offsets for ps4-kexec:

Would you be so kind to compile that for me? Still haven't figured out how to setup the toolchain :/
@tihmstar Will test today.
Awesome thank you! :D
Alright, giving up for today :/
I managed to somehow compile (not sure if i compiled correctly though) using some docker+linux image with some freebsd crosscompiling toolchain.
Tried both:
Either way the page just hangs. Browser doesn't crash (regardless of whether a USB drive with initramfs/kernel is connected or not). I can close the browser, but when i try to re-open the system freezes.
Will wait until you had time to run your tests. I assume the binary i built is bad due to my compiling setup. I'm curious: Is there some information on how to setup a toolchain to build payloads like this?
The linux payload in ps4jb has hardcoded 6.72 offsets. Will fix.
Hi Anyone work on port Linux loader for 7.02? Really looking forward to this thing.
