Wouldn't the AddressSanitizer: "CHECK failed: asan_suppressions.cpp:47 "((suppression_ctx)) != (0)" (0x0, 0x0)" be an internal assertion failure within ASAN? The suppression_ctx (suppression context) pointer is null when it shouldn't be, causing ASAN to crash while trying to handle a memory error.

Recommend not using ASAN in the build process until it's support is better. Check for compiler issues around ASAN on RISC-V. Let "make check" run without ASAN and see if it passes.

Hmm, how do you even turn off ASAN?

@dramforever:matrix.orgdramforever Tristan Ross: audit unconditionally enables asan if found 03:58:31
@rosscomputerguy:matrix.orgTristan RossOh03:58:43
@dramforever:matrix.orgdramforeverin configure.ac03:59:09
@rosscomputerguy:matrix.orgTristan Ross Also, I noticed there's a --with-riscv option in audit that we can enable lol 03:59:11
@rosscomputerguy:matrix.orgTristan RossYeah, I'm trying to turn that off03:59:24
@dramforever:matrix.orgdramforeverwhy is this even an option03:59:34
@rosscomputerguy:matrix.orgTristan RossIdk03:59:51
@dramforever:matrix.orgdramforever maybe it'll work if you turn --with-riscv on? 04:00:05
@rosscomputerguy:matrix.orgTristan RossIt didn't04:00:10
@dramforever:matrix.orgdramforeverrip04:01:01
@rosscomputerguy:matrix.orgTristan RossOtherwise, I could just disable the tests for now04:01:41
@rosscomputerguy:matrix.orgTristan RossIt's not like RISC-V is that heavily adopted that loosing out on the check phase would be bad.04:02:02
@rosscomputerguy:matrix.orgTristan RossAnd there's the NixOS tests04:02:13
@dramforever:matrix.orgdramforever you can sed it out on isRiscv 04:02:32
@rosscomputerguy:matrix.orgTristan RossYes04:02:38
@rosscomputerguy:matrix.orgTristan Rosshttps://github.com/NixOS/nixpkgs/pull/461813 sweet, this worked04:13:12
@rosscomputerguy:matrix.orgTristan RossI didn't see https://github.com/NixOS/nixpkgs/pull/453516 moved the tests out lol04:30:02

In reply to @rosscomputerguy:matrix.org
I didn't see https://github.com/NixOS/nixpkgs/pull/453516 moved the tests out lol
just add it unconditionally and target staging?
05:27:34
@dramforever:matrix.orgdramforeverstaging is unfrozen now too05:27:59
@rosscomputerguy:matrix.orgTristan RossAh05:28:04

Looks like the visionfive2_fw_payload.img should be flashed to /dev/mtd2 instead of /dev/mtd1

@erremilia:matrix.orgerremiliaThis should be fun to play with19:37:02
@hive:the-apothecary.clubEVA-01oooh nice19:38:17
@hive:the-apothecary.clubEVA-01same chip as starfive v2 iirc so it should be somewhat easy to use19:38:37
