There were a lot of unnecessary patches, such as the VRAM patches; as Nicholas Chin has explained to me, the drivers for these machines will just allocate what RAM they want anyway, so in a lot of cases the extra allocated Video RAM simply reduces the total amount of memory for other uses. In general, we have a lot of patches that have existed for years. A much more aggressive sweep will be done in the next major audit, especially when the revisions are updated again.

Subject: [PATCH 50/51] mb/dell: Add S3 SMI handler for Dell Latitudes
|
|
|
|
Integrate the previously added mec5035_smi_sleep() function into
|
|
mainboard code to fix S3 suspend on the SNB/IVB Latitudes and the E7240.
|
|
The E6400 does not require the EC command to sucessfully suspend and
|
|
resume from S3, though sending it does enable the breathing effect on
|
|
the power LED while in S3. Without it, all LEDs turn off during S3.
