Please, my patch (based from Jon's) is huge because it's removing > 200 lines
and it's moving softcursor.c from drivers/video to drivers/video/console where
it belongs. But it is _not_ intrusive. In fact, the majority of the patch consists
of a single logical change which removes the line below from each driver
- .fb_cursor = softcursor;
and removes the line below from drivers/video/Kconfig.
- select FB_SOFT_CURSOR
Our proposal aims to make complex code simpler and big code smaller. Your patch,
on the other hand, although small, introduces another flag FB_HWCURSOR_SOFTCURSOR,
which is redundant, and adds yet another level of complexity to an already too
complex code.
I ask you the same question as Jon. Currently several fbdev drivers have a optional flag to turn on and off the hardware cursor. Should this functionality
be removed and force all fbdev drivers to always have the hardware cursor avaiable. Thus leaving fbcon to control when to use the hardware cursor or the software cursor. It all comes down to who controls when the hardware driver will use the hardware cursor. As noted several drivers have such a flag. You would have to strip that flag out of the drivers as well.
.
BTW, the only drivers that have working hardware cursor support are rivafb, intelfb,
nvidiafb, and i810fb. Except for intelfb, I wrote all of them, if not the driver, the
hardware cursor support. And intelfb's cursor support was based on i810fb.
Erratum: Mach64 also has hardware cursor support, which looks like is working. So
I take the above statement back.
