kms-drm doesn't work on current

[nerzhul]

Hello, i switched to current for devel reasons but i'm unable to have a working kms-drm (i915kms) driver. On FreeBSD 12.1 after recompiling the 12.1 specific driver from ports, it works perfect, before not, i don't remember but maybe a black screen.

On current, first test i did is to use the package from current packages. Both kms-current-dms and drm-devel-kmod are installing but after rebooting, i just have a black screen and i'm unable to switch tty from the blackscreen to a working tty, only going to single user mode and removing the package permits to have a vesa "working" environment (i'm using gnome)

Then i wanted to try to recompile them from ports but i'm facing to 2 compilations issues, on each package

on drm-current-kmod:

--- linux_page.o ---
/usr/ports/graphics/drm-current-kmod/work/kms-drm-ea88121/linuxkpi/gplv2/src/linux_page.c:242:9: error: implicit declaration of function 'vm_page_busy_acquire' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
                        if (!vm_page_busy_acquire(page, VM_ALLOC_WAITFAIL))
                             ^
1 error generated.
*** [linux_page.o] Error code 1

on drm-devel-kmod i have the previous problem and this one:

/usr/ports/graphics/drm-devel-kmod/work/kms-drm-54164ff/linuxkpi/gplv2/src/linux_backlight.c:582:19: error: no member named 'dev_groups' in 'struct class'
        backlight_class->dev_groups = bl_device_groups;

how can i make i915 work on current ?

What do you have in /usr/src? The source must match the kernel you're running.

hello, okay with the proper current in /usr/src it's working properly in terms of compilation

works fine after restarting, it seems this should be noted somewhere to ensure nobody will have same problem as me with multiple trees :)
