After some delay, I finally had a ‘good’ cooling solution for my 8GB Pi4, and resumed testing.. The last Kernel version I had running on it was 5.9-rc4, and everything seemed to be working OK (including 8GB of memory recognised). I then updated to 5.11.18, and found that none of the USB ports worked: # dmesg |grep … Continue reading →
There is now a patch for NVIDIA 465.27 with Kernel 5.13-rc.. at: https://gist.github.com/joanbm/4a9d392e6f2d45c93ef434bda78174e5 – click on ‘Raw’ to download the source.. Thanks (again) to Joan Bruguera for the patch, and Willy Frissen for the notification.. I have tested this with Kernel 5.13-rc1, and the driver now compiles OK, and loads/runs.. Robert Gadsdon. May 10th 2021. … Continue reading →
Kernel 5.13-rc1 is out and brief details are here: http://lkml.iu.edu/hypermail/linux/kernel/2105.1/00457.html VMware 16.1.1 (patched..) compiles and loads OK, but NVIDIA 465.27 compile fails: ……………………………. /home/rgadsdon/NVIDIA-Linux-x86_64-465.27/kernel/nvidia-drm/nvidia-drm-crtc.c: At top level: /home/rgadsdon/NVIDIA-Linux-x86_64-465.27/kernel/nvidia-drm/nvidia-drm-crtc.c:454:23: error: initialization of ‘int (*)(struct drm_plane *, struct drm_atomic_state *)’ from incompatible pointer type ‘int (*)(struct drm_plane *, struct drm_plane_state *)’ [-Werror=incompatible-pointer-types] 454 | .atomic_check = nv_drm_plane_atomic_check, | ^~~~~~~~~~~~~~~~~~~~~~~~~ … Continue reading →
Kernel 5.12 has – finally – been released, and brief details are here: http://lkml.iu.edu/hypermail/linux/kernel/2104.3/00596.html As expected, the latest (patched) VMware 16.1.1 and NVIDIA 465.24.02 compile and load/run OK.. The first release candidate of Kernel 5.13 will be out in about two weeks time, and indications are that this will include quite a large number of changes.. Robert … Continue reading →
I have been carrying out some preliminary tests to see how feasible it is to compile the Linux Kernel, and NVIDIA drivers, and VMware, using the ‘alternative’ to GCC – CLANG.. The kernel compile is relatively easy, and well documented: # make CC=clang HOSTCC=clang -j8 (for a 4-core system) The compile seems to be slower than GCC, … Continue reading →
NVIDIA have released driver 460.67, and details are here: https://forums.developer.nvidia.com/t/linux-solaris-and-freebsd-driver-460-67-long-lived-branch-release/172742 The details mention ‘5.11 release candidates’ but they probably should have said ‘5.12 release candidates’, as the previous driver worked OK with kernel 5.11, and this new one works OK with 5.12 (tested with 5.12-rc3) In other news, I should mention that the KVM/USB crash problems I … Continue reading →
Thanks to Willy Frissen for the info, and joanbm for the patch, which can be found at https://gist.githubusercontent.com/joanbm/7a034ac4b79396c3841040e410ef7e91/raw/b21e792dc0b6f891a4a83d182e0ba9b24b36bd80/nvidia-fix-linux-5.12.patch I have applied this to 460.56, with Kernel 5.12-rc1, and it compiles successfully, and appears to work OK. Unable to do a longer test, as my 5.12-rc1 system still crashes with a USB error, after the KVM switches out.. … Continue reading →
