someone on the nVidia side (user?) confirmed this issue on 4.14.9 kernels: https://devtalk.nvidia.com/default/topic/1028016/linux/patch-for-compiling-v384-98-modules-with-linux-v4-14-9-/post/5228999/#5228999 official patch has not been released by upstream (nvidia of kernel.org) to address this change. as the nvidia.com forum thread suggests, detecting kernel version and conditionally adding the new include (linux/sched/task_stack.h) may be a usable fix. possibly added in the same way as here: > if use kernel_linux && kernel_is ge 4 15; then ^ line from: /usr/portage/x11-drivers/nvidia-drivers/nvidia-drivers-384.98.ebuild
Created attachment 511770 [details] [after_patch] /var/tmp/portage/x11-drivers/nvidia-drivers-384.98/temp/build.log updated build.log (non-failing) as-per nVidia testing, workaround is to update the following: > /kernel/nvidia-uvm/uvm8_va_block.c with the change from 4.14.9 (kernel.org) minor bump: > linux/sched/task_stack.h (attached build.log)
Created attachment 511772 [details, diff] [patch] header fix for build issue on kernel version 4.14.9 this patch has been tested, as-per: (In reply to kuzetsa from comment #7) > /var/tmp/portage/x11-drivers/nvidia-drivers-384.98/temp/build.log [...] using EAPI-6, tested by placing patch in directory: > /etc/portage/patches/x11-drivers/nvidia-drivers-384.98/
(In reply to kuzetsa from comment #6) > if use kernel_linux && kernel_is ge 4 15; then > > ^ line from: > > /usr/portage/x11-drivers/nvidia-drivers/nvidia-drivers-384.98.ebuild sys-kernel/gentoo-sources-4.14.9 is now masked, however: the newly required header is still an issue, additionally: PAGE_TABLE_ISOLATION causes issues with 4.14.11, if enabled (build failure due to new GPL-only symbols) FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol 'cpu_tlbstate' ... nvidia_drivers_versions_check() might need rolled back from: ewarn "<sys-kernel/gentoo-sources-4.15" ewarn "<sys-kernel/vanilla-sources-4.15" to the older: ewarn "<sys-kernel/gentoo-sources-4.14" ewarn "<sys-kernel/vanilla-sources-4.14" upstream has been making several security-related changes which break nvidia drivers packages.
