video/sis: Annotate SiS_DRAMType as __devinitconst

2012-05-08T16:58:27+00:00

SiS_DRAMType is const and only used by sisfb_post_300_rwtest which is
marked __devinit we can annotate SiS_DRAMType with __devinitconst and
move it into the file scope in order to not have it created on the
stack.
This patch decreases the compiled module size by about 100bytes.

And since hardcoded values are bad we use ARRAY_SIZE for determining
the size of SiS_DRAMType ;)

video/sis: Remove unused structs SiS_SDRDRAM_TYPE/SiS_DDRDRAM_TYPE/SiS_DRAMType

2012-05-08T16:58:20+00:00

This patch removes the unused structs SiS_SDRDRAM_TYPE and SiS_DDRDRAM_TYPE
from init.h

These are not used anywhere so we can delete them.

The SiS_DRAMType is identically defined in sis_main.c and only used
there so we can remove it here.

sisfb: use display information in info not in var for panning

2011-08-19T08:34:52+00:00

We must not use any information in the passed var besides xoffset,
yoffset and vmode as otherwise applications might abuse it.

Fix checkpatch.pl warnings in the surrounding code.

sisfb: add support for XGI Z9 DDR2 POST

2011-03-22T06:21:01+00:00

Add support for ZGI Z9 DDR2 POST. The init sequence is from XGI's
xgifb driver.

Tested with ARM board using a PCI card with XGI Z9s and 32 MB DDR2
memory. After a cold reset the POST succeeds.

sisfb: move XGI POST DDR2 bootup code into subroutines

2011-03-22T06:20:45+00:00

Move DDR2 register setting code into separate subroutines. No changes
in functionality.

sisfb: add RAM type detection for XGI Z9

2011-03-22T06:20:33+00:00

Detect the XGI Z9 RAM type as "documented" by the XGI's xgifb driver.

sisfb: add subroutine for detecting XGI Z9

2011-03-22T06:20:30+00:00

Z7 and Z9 have the same PCI ID, so additional checking is needed to
detect Z9. The method was "documented" in XGI's xgifb driver.

sisfb: move XGI POST RAM type detection into a subroutine

2011-03-22T06:20:19+00:00

Move XGI POST RAM type detection into a separate subroutine to make
further code changes easier. No changes in functionality

sisfb: POST should fail if R/W test fails

2011-03-22T06:20:05+00:00

Currently there is no indication if R/W test fails during POST. This can
happen e.g. when user plugs in a card with unsupported type of memory.
Since the driver will be unusable, it's better to fail the whole POST
if the memory cannot be configured properly.

sisfb: eliminate compiler warnings

2010-12-22T03:57:27+00:00

Convert some bit masks to 8-bit values to avoid the following compiler
warnings:

drivers/video/sis/init301.c:5855: warning: large integer implicitly truncated to unsigned type
