2010-04-27Since some people disapprove of white space cleanups mixed in regular commitsStefan Reinauer
while others dislike them being extra commits, let's clean them up once and for all for the existing code. If it's ugly, let it only be ugly once :-) Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5507 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2010-01-17msrtool: Read both MSR values from file in diff modePeter Stuge
Previously, msrtool would assume that MSR values should be compared between stored value in file and current value in hardware which msrtool was running on. This does not always fit the use case and with this change msrtool can now compare two sets of MSR values stored in a file. If only one MSR value is stored in the file, msrtool will behave as before, and read the second MSR value from hardware. This change means that msrtool does not always need access to the system MSR functions so it can now be run as a regular user when using diff mode with both MSR values stored in the file.

2010-01-17msrtool: Add endptr to str2msr() showing how many characters were parsedPeter Stuge
This also introduces a small change in the user interface for immediate mode (-i). Previously, whitespace could separate high and low words in an MSR as such: msrtool -i 4c00000f='f2f100ff 56960004' That is no longer allowed, a space character now ends the MSR value. Any other character can still be used as separator however, so the following syntax still works as expected: msrtool -i 4c00000f=f2f100ff:56960004 Signed-off-by: Peter Stuge <peter@stuge.se> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5032 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

2010-01-16msrtool: Remove indent by using continue inside for() to avoid an if blockPeter Stuge
The only actual code change is from if (.. >= 1) { } to if (.. < 1) continue so this is pretty trivial. Signed-off-by: Peter Stuge <peter@stuge.se> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5020 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

2008-11-22msrtool: Release Candidate 1Peter Stuge
msrtool can decode MSRs and print the value of every field in human readable form. It can also be used to save a set of MSRs to a file, and at a later time compare the saved values with current values in hardware.
