Guide shows incorrect usage of proftool, which is confusing. If proftool is used w/o '-o' argument it complains like following $ ./sandbox/tools/proftool -m sandbox/System.map -t trace dump-ftrace > trace.dat Must provide trace data, System.map file and output file Usage: proftool [-cmtv] <cmd> <profdata> s/>/-o/ fixes it and proftool outputs decoded data to trace.dat Signed-off-by: Pavel Skripkin <paskripkin@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
This patch series adds support for ZFS listing and load to u-boot. To Enable zfs ls and load commands, modify the board specific config file with #define CONFIG_CMD_ZFS Steps to test: 1. After applying the patch, zfs specific commands can be seen in the boot loader prompt using UBOOT #help zfsload- load binary file from a ZFS file system zfsls - list files in a directory (default /) 2. To list the files in zfs pool, device or partition, execute zfsls <interface> <dev[:part]> [POOL/@/dir/file] For example: UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/ 3. To read and load a file from an ZFS formatted partition to RAM, execute zfsload <interface> <dev[:part]> [addr] [filename] [bytes] For example: UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage References : -- ZFS GRUB sources from Solaris GRUB-0.97 -- GRUB Bazaar repository Jorgen Lundman <lundman at lundman.net> 2012.
