[Mesa-dev] [PATCH v3] HUD: Add support for block I/O, network I/O and lmsensor stats
Steven Toth
stoth at kernellabs.com
Tue Sep 13 20:21:23 UTC 2016
V3: Flatten the entire patchset ready for the ML
V2: Additional seperate patches based on feedback
a) configure.ac: Add a comment related to libsensors
b) HUD: Disable Block/NIC I/O stats by default.
Implement configuration option --enable-gallium-extra-hud=yes
and enable both statistics when this option is enabled.
c) Configure.ac: Minor cleanup to user visible configuration settings
d) Configure.ac: HUD stats - build system improvements
Move the -lsensors out of a deeper Makefile, bring it into the configure.ac.
Also, rename a compiler directive to more closely follow the standard.
V1: Initial release to the ML
Three new features:
1. Disk/block I/O device read/write stats MB/ps.
2. Network Interface RX/TX transfer statistics as a percentage
of the overall NIC speed.
3. lmsensor power, voltage and temperature sensors.
The lmsensor changes makes a dependency on libsensors so support
so the change is opt out by default.
