Revision as of 12:00, 23 October 2013

Purpose of this page and table is to evaluate the risk and thus decide about fitness for CSSU kernel, of all patches available from latest KP

Changes:
2012-11-03 - [freemangordon] Initial draft 
2012-11-03 - [Joerg_rw] major restructuring to sortable true table, 
                        added coloumns .ko (means only kernel module domain) and 
                        zImg (means massive impact and risk due to edits in kernel core)  
2012-11-03 - [Pali] added info about Nokia patches and patches disabled in KP
2013-01-24 - [Pali] updated patches list to match kp52 version
2013-02-02 - [Pali] updated info about patches
2013-08-03 - [freemangordon] more patches assessed
                             add underscores around impact in an attempt to make table look better
2013-08-11 - [Pali] updated info about patches
2013-10-12 - [Pali] disabled usb host mode patches, updated colors
2013-10-23 - [Pali] added kp53 patches

bq drivers are disabled because are experimental and not working with bme

usb host mode patches are disabled because using bq drivers

overclock patches are disabled because breaking powertop


TODO: Need to fix modules.postrm and modules.postinst scripts which chaning /sbin/preinit and /etc/modprobe.d/bridgedriver
