The redundant fb helpers .load_lut, .gamma_set and .gamma_get are no longer used. Remove the dead code and hook up the crtc .gamma_set to use the crtc gamma_store directly instead of duplicating that info locally.

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. I have obviously not tested all of this with more than a compile, but patches 1 and 3...

...! I made some workaround to this problem. I have moved all databases from /var/lib/samba to /var/lib/samba_lock folder, add: lock directory = /var/lib/samba_lock to smb.conf and it is working now - i can log into domain, i can browse machine list etc. but in logs i have many errors like that: lut 14 23:46:31 codo smbd[13803]: [2004/02/14 23:46:31, 0, pid=13803, effective(1002, 221), real(1002, 0)] groupdb/mapping.c:get_group_from_gid(655) lut 14 23:46:31 codo smbd[13803]: failed to initialize group mappingget_alias_user_groups: gid of user boka doesn't exist.

This is what was done prior to the big refactor in kernel 3.8, and what was done by xf86-video-nv. Experimentally, it seems like there's some sort of issue with the high-res lut to be used there. Tested on G92. This ends up mattering because fbcon/fbdev chooses the C8 fb format for low-vram systems, which can occur with some IGP-based configurations with little "stolen" vram.

Unfortunately the ABI is a little annoying around almost requiring a 256-entry lut. While that is being worked out, allow proper mapping of colors in 30bpp framebuffers. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> --- If I bump the gamma size to 1024, then all existing software will start failing since the gamma set ioctl expects the size to match.

In xbgr2101010 mode, the gpu seems to properly interpolate between the 256 (or 257) hw lut slots, as far as my measurments go. The X-Server maintains separate color palettes, per-x-screen xf86vidmode gamma lut'...

While certain modeset operations on gv100+ need us to temporarily disable the LUT, we make the mistake of sometimes neglecting to reprogram the LUT after such modesets. In particular, moving a head from one encoder to another seems to trigger this quite often. GV100+ is very picky about having a LUT in most scenarios, so this causes the display engine to hang with the following...
