Having the gentoo-sources kernel and trying to load the vmwgfx module gives "Unknown symbol" errors. Reproducible: Always Steps to Reproduce: Have a gentoo guest running on VirtualBox with a VMSVGA graphics card and 3D acceleration enabled. emerge sys-kernel/gentoo-sources, configure kernel by enabling DRM and VMware's DRM: Device Drivers -> Graphics support -> <*> Direct Rendering Manager (XFree86 ...) <M> DRM driver for VMware Virtual GPU [*] Enable framebuffer console under vmwgfx by default make all, make install, make modules_install and reboot. Run modprobe vmwgfx. Actual Results: kernel: vmwgfx: Unknown symbol clean_record_shared_mapping_range (err -2) kernel: vmwgfx: Unknown symbol wp_shared_mapping_range (err -2) Expected Results: No errors. These errors don't happen by getting the kernel from kernel.org. emerge --info gives the following output: Portage 3.0.18 (python 3.8.8-final-0, default/linux/amd64/17.1/systemd, gcc-10.2.0,

Is this enabled in your .config ? CONFIG_MAPPING_DIRTY_HELPERS Can you attach it, please?
Created attachment 709188 [details] .config It is enabled, CONFIG_MAPPING_DIRTY_HELPERS=y
Interesting, your .config worked for me outside VirtualBox and with gcc 11.1.0 ~ # lsmod Module Size Used by vmwgfx 344064 0 ttm 81920 1 vmwgfx
I don't think there's much else I can do here, you way want to work with upstream if this is still an issue
