msm8937: KGSL doesn't work and sometimes makes kp when tries to load fw #1
Comments
another log from Xiaomi Redmi 4X (santoni) |
Try this.. we need this revert as we dont have that new gpu firmware hence it crashes... Tested on asus, xiaomi 4.19 kernels on our org @Atom-X-Devs Edit:- I reviewed your commit history in default branch and its missing this commit. Our stock kernel revisions also have this change btw.. so its indeed needed |
@ElectroPerf I tried reverting this, it didn't help at all. We tried different combinations of fw, since msm8937 device doesn't have adreno fw signed |
Hmm, this seems interesting. [ 11.807139] can't get fw name. Maybe its from gpu driver? Its not catching proper file so it fail to load and crash. Something like race condition between gpu driver and mounting partition. Proably like that becuse of these logs: kgsl kgsl-3d0: Falling back to syfs fallback for: a530_pm4.fw |
kgsl kgsl-3d0: Falling back to syfs fallback for: a530_pm4.fw This happens even on sdm660, so we can ignore that can't get fw name. It's from sensors as far as I remember |

Debian's clang carries a patch that makes the default FPU mode 'vfp3-d16' instead of 'neon' for 'armv7-a' to avoid generating NEON instructions on hardware that does not support them: https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/raw/5a61ca6f21b4ad8c6ac4970e5ea5a7b5b4486d22/debian/patches/clang-arm-default-vfp3-on-armv7a.patch https://bugs.debian.org/841474 https://bugs.debian.org/842142 https://bugs.debian.org/914268 This results in the following build error when clang's integrated assembler is used because the '.arch' directive overrides the '.fpu' directive: arch/arm/crypto/curve25519-core.S:25:2: error: instruction requires: NEON vmov.i32 q0, #1 ^ arch/arm/crypto/curve25519-core.S:26:2: error: instruction requires: NEON vshr.u64 q1, q0, #7 ^ arch/arm/crypto/curve25519-core.S:27:2: error: instruction requires: NEON vshr.u64 q0, q0, #8 ^ arch/arm/crypto/curve25519-core.S:28:2: error: instruction requires: NEON vmov.i32 d4, #19 ^ Shuffle the order of the '.arch' and '.fpu' directives so that the code builds regardless of the default FPU mode. This has been tested against both clang with and without Debian's patch and GCC.

… UAF [ Upstream commit 226fae124b2dac217ea5436060d623ff3385bc34 ] After a call to console_unlock() in vcs_read() the vc_data struct can be freed by vc_deallocate(). Because of that, the struct vc_data pointer load must be done at the top of while loop in vcs_read() to avoid a UAF when vcs_size() is called. Syzkaller reported a UAF in vcs_size().
