Package: nvidia-kernel-dkms Version: 550.163.01-4 Followup-For: Bug #1130057 Severity: important
Full Technical Report: I am providing additional evidence and logs regarding the build failure of the NVIDIA 550.163.01-4 driver on the current 6.19 kernel series in Debian Testing and Sid. The issue persists even after upgrading to the latest headers in Sid (6.19.6-2). System Environment: - OS: Debian GNU/Linux Trixie (testing) / Sid - Kernel: 6.19.6+deb14-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.19.6-1 - Kernel (Sid): 6.19.6+deb14+1-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.19.6-2 - Driver Version: 550.163.01-4 (nvidia-kernel-dkms and nvidia-open-kernel-dkms) - Compiler: gcc (Debian 14.2.0-16) 14.2.0 DKMS Build Failure Analysis: The compilation fails early in the DKMS process. Below are the specific errors extracted from make.log which highlight the breakage caused by Linux 6.19 API changes: 1. Removal of __vm_flags in vm_area_struct: The kernel has finalized the transition to protected VMA flags. Direct access to __vm_flags or bitwise operations on it now results in compilation errors. Error log: ././common/inc/nv-mm.h:315:25: error: 'struct vm_area_struct' has no member named '__vm_flags'; did you mean 'vm_flags'? ././common/inc/nv-mm.h:327:25: error: 'struct vm_area_struct' has no member named '__vm_flags'; did you mean 'vm_flags'? 2. Deprecation of in_irq(): The legacy macro in_irq() has been removed in the 6.19 series. Error log: ././common/inc/nv-time.h:145:9: error: implicit declaration of function 'in_irq' [-Wimplicit-function-declaration] 3. Changes in struct dma_map_ops: The map_resource member is no longer available in the DMA operations structure as defined in nvidia/nv-dma.c. Error log: nvidia/nv-dma.c:799:16: error: 'const struct dma_map_ops' has no member named 'map_resource' Steps to Reproduce: 1. Install linux-image-6.19.6-amd64 and linux-headers-6.19.6-amd64 from Testing or Sid. 2. Attempt to install nvidia-kernel-dkms or nvidia-open-kernel-dkms. 3. The installation fails during the DKMS trigger with exit status 10. Conclusion and Impact: The current 550.163.01-4 source package is incompatible with the default kernel provided in Testing/Sid. This leaves users with no working NVIDIA driver unless they manually downgrade and pin the kernel to the 6.18 series or apply manual patches to the source. It is requested to backport compatibility patches or fast-track the transition to newer driver branches (565.x/570.x).
