Description Hiroo Ono 2017-03-16 21:47:03 UTC 
Created attachment 180886 [details]
add tunables equivalent to Linux's module parameters.

On a early PowerMac G5 DP, to get the radeonkms kernel module loaded and working properly, we need to force Radeon 9600 card to PCI mode.
On Linux, it is done by specifying a module parameter, but its FreeBSD equvalent, tunable is not defined in sys/dev/drm2/radeon/radeon_drv.c.
Attached patch defines tunables for each "module parameters" of Linux in radeon_drv.c.

Tested on a 12.0-CURRENT/powerpc64 r313561.
