KERNEL – 4.6-rc1 Released – OK with Latest VMware, Breaks NVIDIA – and a Possible Fix..

Adventures With Linux ™ Posted on by

Just  installed Kernel 4.6-rc1 on the test system.

Depending on your configuration, you may encounter a compilation error:

CC drivers/thermal/mtk_thermal.o
drivers/thermal/mtk_thermal.c: In function ‘mtk_thermal_probe’:
drivers/thermal/mtk_thermal.c:560:8: error: implicit declaration of function ‘device_reset’ [-Werror=implicit-function-declaration]
 ret = device_reset(&pdev->dev);
 ^
cc1: some warnings being treated as errors
..................................

This is due to a Mediatek thermal driver being ‘selected’ by default (and in error?), and the simple fix is to deselect it!    After that, the kernel should compile OK..

VMware 12.1.0 compiles and loads/runs OK.

NVIDIA 361.28 compile fails:

/home/rgadsdon/NVIDIA-Linux-x86_64-361.28/kernel/nvidia-uvm/uvm_lite.c: In function ‘_fault_common’:
/home/rgadsdon/NVIDIA-Linux-x86_64-361.28/kernel/nvidia-uvm/uvm_lite.c:1286:20: error: ‘VM_FAULT_MINOR’ undeclared (first use in this function)
 retValue = VM_FAULT_MINOR;
 ^

/usr/src/linux-4.6-rc1/Makefile:1427: recipe for target '_module_/home/rgadsdon/NVIDIA-Linux-x86_64-361.28/kernel' failed

364.12 (beta) compile has a similar error..

There is a quick-and-dirty patch for this, and a second patch for a subsequent compile error with 364.12, here:
https://devtalk.nvidia.com/default/topic/926824/364-12-won-t-compile-against-latest-git-tree-patches-for-4-6-0-rc1-included-/

I have applied both patches to 364.12, and it compiles OK against 4.6-rc1..

The first patch is all that is necessary for 361.28, and it then compiles OK..

  1. Hi!

    vmware doesn’t compile with newer rc versions. I tried the newest from vmware (VMware Workstation 12.1.1 build-3770994)

    The issue is that a macro which used to suck was changed in the kernel: commit c12d2da56d0e07d230968ee2305aaa86b93a6832

    relevant text is:
    old:
    ret = get_user_pages(current, current->mm, address, 1, 1, 0, &page, NULL);

    new:
    ret = get_user_pages(address, 1, 1, 0, &page, NULL);

    vmware has two modules, vmnet and vmmod which have both of those.

    although as I’m writing this out to you, I could probably combine a few things.

    Anyway, thank you for your previous post patching vmmon! This is nowhere near as challenging, and probably the easiest “it doesn’t compile” I have ever seen (since everything was stated, and the git log had an explicit statement of what to change for the kernel), but maybe I have saved someone else a min or two of time. I figure if I get 100+people, that’s maybe an hour or so saved, which is nice!

  2. Well that was ugly.

    just followed the lkml syntax and added/changed:

    # if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 6, 0)
    ret = get_user_pages(address, 1, 1, 0, &page, NULL);
    # else
    ret = get_user_pages(current, current->mm, address, 1, 1, 0, &page, NULL);
    # endif

    files were:
    vmmon-only/linux/hostif.c (line 1166)
    vmnet-only/userif.c (line 116)

    • Many thanks for spotting that – I had not yet tested it..! And thanks also for the patches… I tried the first (long-form) one, and had to slightly modify the format to get the vmnet portion to apply, for some reason..:
