V3 Patch - Driver for Freescale 8610 and 5121 DIU
Subsystems (4)
The following two patches are the 3rd version of the DIU patch for Freescale 8610 and 5121. It fixed the issues according to the feedback from Andrew Morton.
Andrew, incremental patches are available if requested.
Regards,
York
PATCH v3 1/2 Driver for Freescale 8610 and 5121 DIU
The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0 plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2 plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4 Special ioctls support AOIs
All /dev/fb* can be used as regular frame buffer devices, except hardware change can only be made through /dev/fb0. Changing pixel clock has no effect on other fbs.
Limitation of usage of AOIs:
AOIs on the same plane can not be horizonally overlapped
AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1 AOIs can not beyond phisical display area. Application should check AOI geometry before changing physical resolution on /dev/fb0
required command line parameters to preallocate memory for frame buffer diufb=15M
optional command line parameters to set modes and monitor video=fslfb:[resolution][,bpp][,monitor]
Syntax:
Resolution
xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60
Bpp
bpp=32, bpp=24, or bpp=16
Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDS
Note: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching monirot port for MPC5121ADS has no effect.
If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

Could you split some of this up into separate functions at lower indentation levels to make it more readable?

As I said in an internal review, this is not enough, and it's inefficient. Read rather than write, and do so only once per cache line, but the size you access has to be at least 13/8 of the cache size for an 8-way plru cache.

These identifiers are too general for use as global symbols. I'd suggest renaming them to diu_coherence_data and diu_coherence_data_phy. Or make them static - I didn't check.
I'll duck this version of the patches, as Scott's comments looked rather substantial.
