sh: dma: Make PVR2 DMA configurable.

2009-03-17T00:30:36+00:00

With arch/sh/drivers/dma/ always being built, the Dreamcast DMA engines
are being unconditionally built in, regardless of whether the DMA API is
enabled or not. This is a regression from previous behaviour, but there
is not much advantage in building them all in unconditionally regardless.
Add a new config option to make it optional, and update the only user of
it to reflect that.

fb: pvr2fb: Fix up remaining section mismatch.

2008-03-06T04:39:18+00:00

Building with CONFIG_DEBUG_SECTION_MISMATCH=y reports:

  CC      drivers/video/pvr2fb.o
  LD      drivers/video/built-in.o
WARNING: drivers/video/built-in.o(.text+0xb9b0): Section mismatch in reference from the function pvr2fb_check_var() to the variable .devinit.data:pvr2_fix
The function pvr2fb_check_var() references
the variable __devinitdata pvr2_fix.
This is often because pvr2fb_check_var lacks a __devinitdata
annotation or the annotation of pvr2_fix is wrong.

This is obviously crap as no such reference exists, but it's a bit
closer to reality from older versions which blamed the PCI table. The
real problem was a reference to pvr2_var.vmode from pvr2fb_check_var(),
as pvr2_var is flagged as __devinitdata (pvr2_fix is also, so at least
that part is right).

pvr2_var.vmode is just a fancy way of saying FB_VMODE_NONINTERLACED, so
we just reference that explicitly instead.

fbdev: change asm/uaccess.h to linux/uaccess.h

2007-10-16T16:43:17+00:00

This patch replaces  with  after the
checkpatch.pl hint.  The include of  is removed if the driver
does not use it.

fb: pvr2fb: Shared IRQ for dreamcast pvr2.

2007-09-21T02:57:51+00:00

The maple bus driver (http://lkml.org/lkml/2007/9/4/165) uses hardware
synchronisation between the maple bus and the VBLANK to poll the maple
bus. This patch makes the interrupt shareable.

By definition the interrupt is for both devices.

pvr2fb: Consolidated cleanup of pvr2fb.c

2007-08-11T22:47:40+00:00

- better handling of the pvr2 registers based on more up to date information.

Testing shows that it seems to work pretty well at 16bpp, 24bpp and 32bpp -
including proper rendering of the boot logo at all levels (previously this was
a bit broken even at 16bpp) and giving white against black text.  Really
detailed testing (eg with X11) requires support for the maple bus - which
isn't (currently - next project assuming this is okay) available, but I have
no reason to think this is broken.

pvr2fb: Fix oops when pseudo_palette is written

2007-08-11T22:47:40+00:00

Reported by: Adrian McMenamin 

This driver will oops when the pseudo_palette[] is written as u32 but not when
written as u16.  When written as u32, it corrupts the adjacent 'mmio_base'
field of struct pvr2fb_par.  Fix by using framebuffer_alloc()/release() to
allocate struct fb_info and struct pvr2fb_par, and create the pseudo_palette[]
as part of struct pvr2fb_par.

pvr2fb: fix pseudo_palette array overrun and typecast

2007-07-17T17:23:12+00:00

- the pseudo_palette has only 16 elements. Do not write if regno (the array
  index) is more than 15.
- if using generic drawing libraries, the typecast of pseudo_palette is
  always u32 *
