# amdtools

Various tools for AMD platforms
|
|
|
|
## A tool to update the SPI speed set in the EFS table
|
|
This works for Stoney Ridge and Zen class AMD processors.
|
|
- update_efs_spi_speed
|
|
|
|
## A set of tools to compare (extended) K8 memory settings.
|
|
- k8-compare-pci-space.pl
|
|
- k8-interpret-extended-memory-settings.pl
|
|
- k8-read-mem-settings.sh
|
|
- parse-bkdg.pl
|
|
|
|
Before you can use them, you need to massage the relevant BKDG
|
|
sections into useable data. Here's how.
|
|
|
|
1. First, you need to acquire a copy of the K8 BKDG. Go here:
|
|
Rev F: http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/32559.pdf
|
|
2. Make sure pdftotext is installed (it's in the poppler-utils
|
|
package on Debian/Ubuntu).
|
|
3. Run the bkdg through pdftotext:
|
|
`pdftotext -layout 32559.pdf 32559.txt`
|
|
4. Extract sections 4.5.15 - 4.5.19 from the file, and save it
|
|
separately, say as bkdg-raw.data.
|
|
5. Finally run the txt file through the parse-bkdg.pl script like so:
|
|
`parse-bkdg.pl < bkdg-raw.data > bkdg.data`
|
|
|
|
Now we have the bkdg.data file that is used by the other scripts.
|
|
|
|
If you want to test the scripts without doing all this work, you
|
|
can use some sample input files from the 'example_input/' directory.
