Another output after i figure out i need to put .debug where the ubt is located to get full error output

This is not really a programmer question. I think it does not belong to Stackoverflow. Maybe look for a public forum for exagear — Michael S, Aug 15 '21 at 19:27

mmap(0x880000000000, 104, ... looks weird to me. The 2nd arg (length) should be a multiple of 4096, so I'm surprised at it returning ENOMEM instead of EINVAL.

Perhaps that's because 0x880000000000 isn't a canonical address for x86-64, unless you're on a system using PML5 for 57-bit virtual addresses (instead of the standard 48-bit that you get with the standard 4 levels of page tables). 0x880000000000 has bit #48 set, so the high 16 bits should all be 1 for it to be correctly sign-extended. (But then it would be a kernel address and user-space couldn't map it.)

So even with a valid (multiple-of-4096) length arg, this mmap couldn't work except on an Ice Lake or newer system with PML5 enabled.

The Linux mmap(2) man page says that should result in EINVAL as well: EINVAL - We don't like addr, length, or offset (e.g., they are too large, or not aligned on a page boundary).

(Note that Stack Overflow is for programming questions. That's the programming reason why this mmap doesn't work, I think. Questions about how to use some existing closed-source(?) software are off-topic, and I don't know anything about that program.)

Well that program is x86_64 emulator on arm64 – amera Aug 16 '21 at 01:05
@amera: Oh you're running this *on* ARM64? I was assuming the reverse; running on x86_64 to emulate a phone, since the question is tagged `[x86]`, not `[x86-emulation] [arm64]`. IDK what restrictions AArch64 has on valid addresses, but I think 104 is still not a valid page size. – Peter Cordes Aug 16 '21 at 01:14
I found this ``Q7: ExaGear Virtual address range used ？ A: The virtual address length used in the current version is 48bit, If the virtual address space allowed by the kernel is less than this length , Occurs at startup segment fault. `` – amera Aug 17 '21 at 03:40
