Created attachment 433820 [details, diff] Patch to run against linux kernel 4.3+ Ran into this when upgrading to sys-kernel/gentoo-sources-4.4.6 recently. The old nvidia-drivers ebuild will compile and install successfully against the new kernel, but the resulting module fails to load. Instead it produces unknown symbol errors with mtrr_add and mtrr_del. I tried the patch suggested here: https://devtalk.nvidia.com/default/topic/893282/304-128-and-kernel-4-3-can-compile-but-cannot-insert-it-mtrr-symbols-related-errors-/ and it seems to work (attached as well). I suppose nVidia might release a patched version, but until then, this might be useful to others with these old cards.
i can confirm this as well. Debian has a patch for the kernel/nv-linux.h file: https://anonscm.debian.org/viewvc/pkg-nvidia/packages/nvidia-graphics-drivers-legacy-304xx/trunk/debian/module/debian/patches/disable-mtrr.patch?view=markup Their bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=809324 This patch at least load the driver: (based on debian description). --- a/kernel/nv-linux.h +++ b/kernel/nv-linux.h @@ -256,6 +256,15 @@ #include <linux/seq_file.h> #endif +/* + * As of version 304.131, os-agp.c and os-mtrr.c still use deprecated + * kernel APIs for mtrr which are no longer exported since 4.3, causing + * the module to error out when loaded. + */ +#if LINUX_VERSION_CODE >= KERNEL_VERSION(4,3,0) +#undef CONFIG_MTRR +#endif + #if !defined(NV_VMWARE) && defined(CONFIG_MTRR) #include <asm/mtrr.h> #endif Before: [ 1636.024448] nvidia: Unknown symbol mtrr_del (err 0) [ 1636.024771] nvidia: Unknown symbol mtrr_add (err 0) After: [ 3735.439605] ACPI: PCI Interrupt Link [SGRU] enabled at IRQ 23 [ 3735.439652] vgaarb: device changed decodes: PCI:0000:02:00.0,olddecodes=io+mem,decodes=none:owns=io+mem [ 3735.440156] [drm] Initialized nvidia-drm 0.0.0 20150116 for 0000:02:00.0 on minor 0 [ 3735.440189] NVRM: loading NVIDIA UNIX x86 Kernel Module 304.131 Sun Nov 8 21:44:08 PST 2015 [ 3735.503470] ACPI Warning: \_SB_.PCI0.IXVE.IGPU._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20150930/nsarguments-95) [ 3735.503519] ACPI Warning: \_SB_.PCI0.IXVE.IGPU._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20150930/nsarguments-95) [ 3735.503597] ACPI Warning: \_SB_.PCI0.IXVE.IGPU._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20150930/nsarguments-95) [ 3735.503635] ACPI Warning: \_SB_.PCI0.IXVE.IGPU._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20150930/nsarguments-95) [ 3735.503669] ACPI Warning: \_SB_.PCI0.IXVE.IGPU._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20150930/nsarguments-95) [ 3735.503701] ACPI Warning: \_SB_.PCI0.IXVE.IGPU._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20150930/nsarguments-95) [ 3735.503733] ACPI Warning: \_SB_.PCI0.IXVE.IGPU._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20150930/nsarguments-95)
