1. How to Use

1.1. Installation

1. Clone this repo to local machine.

# git clone https://github.com/chelsiocudbg/SW_Patches.git /home/SW_Patches

2. Patch the kernel source. Apply all the patches in the order of patch numbering.

# cd <path to kernel source>
# for i in /home/SW_Patches/patches/upstream/*.patch; do patch -p1 < $i; done
# for i in /home/SW_Patches/patches/cudbg/*.patch; do patch -p1 < $i; done

3. Ensure that all the Chelsio driver modules are selected in the kernel configuration file.

4. Build and install the kernel.

5. Install the Firmware and the configuration files.

# cp /home/SW_Patches/firmware/* /lib/firmware/cxgb4/

6. Install CUDBG and chdebug.

# cp /home/SW_Patches/tools/* /sbin/

7. Reboot your machine into the newly installed kernel.

1.2. Firmware Update

The firmware (v1.16.33.0) is installed on the system, typically in /lib/firmware/cxgb4, and the driver will auto-load the firmware if an update is required. The kernel must be configured to enable userspace firmware loading support:

Device Drivers -> Generic Driver Options -> Userspace firmware loading support

The firmware version can be verified using ethtool:

# ethtool -i <iface>

1.3. CUDBG

Chelsio Unified Debug (CUDBG) Library is a platform independent library developed to provide hassle free debug log collection. To collect all the logs,

# cudbg_app --collect all ethX <outfilename>

where ethX is the Chelsio Interface.

NOTE: To know more options of cudbg, refer cudbg help by typing # cudbg_app -h
