pawn's Issues

failed build on ubuntu 21.10

build error:

/home/raf/repo/pawn/build/_deps/absl-src/absl/debugging/failure_signal_handler.cc:139:32: error: no matching function for call to ‘max(long int, int)’
139 | size_t stack_size = (std::max(SIGSTKSZ, 65536) + page_mask) & ~page_mask;

Unsupported Intel ChipSet v2.0

After finally got this version of pawn to work on Ubuntu 18.0 I still get this message:

pawn 0.2 (@internal, Jan 24 2023, debug build), (c)2014-2022 Google LLC.
Acquiring I/O port read permissions, this may fail...
Reading chipset LPC device identification: VID: 0x8086 DID: 0xA150 RID: 0x31 (49)
F /home/ubuntu/Downloads/pawn-main/pawn/pawn.cc:80] Unsupported Intel chipset, check hardware id.Aborted

Is there any chance to get this error fixed?

Thanks in advance

build errors

Hi, I encountered the following errors when running mkdir build & cd build & cmake .. & make

Unsupported Intel chipset

Not working on LG_gram 2018

SMM_BWP result hardcoded?

It appears that the SMM_BWP will always show up as 0. The ich8 chipset definition hardcodes this to 0, and the others appear to inherit their definition of the BIOS Control Register without change.

0, // Reserved, SMM_BWP on PCH platforms.

Checked with lspci and chipsec to confirm discrepancy.
