Linux Kernel Configurations de drhuvvyas90 and bcm2709_defconfig
started 2017-12-17 Sunday
Overview
These notes regard Ted's search for a working Linux kernel configuration to make the kernel run on a Raspberry Pi 2 dev board, and to also run correctly in QEMU 2.10.x target hardware emulator. Instructions for compiling custom kernels for Rpi boards on Raspberry Pi's web site tutorials pages appear out of date, or at least present steps which don't succeed when followed step by step. Ted now comparing a working Rpi kernel's configuration with the one from Raspberry Pi's tutorial. While creating a third configuration which is an incremental synchronizing of bcm2709_defconf kernel configuration, making this "recipe" option by option match drhuvvyas90's 4.4.34 "Jessie" kernel configuration, there are some situation where options may not be available to change, situations including:
- given kernel option in source tree but not adjustable via menuconfig tool
- kernel option is conditionally available on a "parent" option which is differently defined between kernel 4.4.34 and 4.4.50 releases
- kernel option is defined in one of 4.4.34 and 4.4.50 kernel releases but not defined in the other
Table 1 in this notes page holds kernel configuration files broken into their respective sections, where sections are indicated by kernel developers or kernel configuration tool developers by three consecutive comment lines, where middle of these three comments expresses 'section title' and the first and last comments are the comment symbol '#' only. The second table, table 2 in this project notes page contains each original kernel config file in an easily copy-and-paste form. We can't get that when splitting text files by sections into cells of a hypertext mark-up table.
Note: the last line in both kernel configuration files on this page reads "# CONFIG_VIRTUALIZATION is not set".
Note: there is a green block between the two tables, to aid in scrolling based page navigation and give indication when second table is at hand.
