* Add support for lopper to generate partial dtsMichal Orzel2022-12-092-20/+79
| | | | | | | | | | | | | | | | | | | | | | Currently ImageBuilder can compile and merge partial dts obtained from a repository specified using PASSTHROUGH_DTS_REPO. With the recent changes done in the lopper, we can use it to generate partial dts automatically (to some extent as this is still an early support). Introduce LOPPER_PATH option to specify a path to a lopper.py script, the main script in the Lopper repository, that if set, will invoke lopper to generate partial dts for the passthrough devices specified in DOMU_PASSTHROUGH_PATHS. Introduce LOPPER_CMD option to specify custom command line arguments (if needed) for lopper's extract assist. Example usage: LOPPER_PATH="/home/user/lopper/lopper.py" DOMU_PASSTHROUGH_PATHS[0]="/axi/spi@ff0f0000 /axi/serial@ff010000" Signed-off-by: Michal Orzel <michal.orzel@amd.com> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org>
* Refactor sanity_check_partial_dtsMichal Orzel2022-12-091-5/+6
| | | | | | | | | | | | | | | | Currently function sanity_check_partial_dts from scripts/common takes three arguments where the last two (repo, dir) are used always in conjuction to form a path to a directory storing partial dts. Modify the function to take only two arguments where the second one is to be a path to a directory storing partial dts. This will help reusing this function in the future to perform sanity checks on partial dts that do not originate from a repository. Modify compile_merge_partial_dts to take this change into account.

For example, we can have "fatload mmc 0:2" as LOAD_CMD but the files would need to be loaded from the /boot folder within the 2nd partition, not from the root ("/"). By specifying the "-p <path>" parameter when running the script, paths like "/boot" can be automatically prepended to the generated u-boot commands used to load the files in board's memory.

DOMU_STATIC_MEM[number]="baseaddr1 size1 ... baseaddrN sizeN" The parameter specifies the host physical address regions to be statically allocated to the VM.

For instance, DOMU_STATIC_MEM[0]="0x30000000 0x10000000 0x50000000 0x20000000" indicates that the host memory regions [0x30000000, 0x40000000) and [0x50000000, 0x70000000) are statically allocated to the first dom0less VM. Since currently it is not possible for a VM to have a mix of both statically and non-statically allocated memory regions, when DOMU_STATIC_MEM is specified, adjust VM's memory size to equal the amount of statically allocated memory.

* handle correctly symlinks in parent directoriesStefano Stabellini2022-04-191-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | Commit b9e2809fce57 introduced support for symlinks when specified in the config file for one of the binaries, but it breaks if there is a symlink in one of the parent directories. This patch fixes the behavior by doing the following: - get the absolute "real" path of the target file using realpath, not resolving symlinks for the parameter path (parents still get resolved) - get the absolute "real" path of the current directory using realpath This is necessary so that the two paths match in terms of symlinks resolution. - strip the base directory from the absolute path. The result is the target file with a path relative to the current directory without symlink resolution, but correctly handling the case where symlinks are presents in the parent directories.

In our approach, the functions in common script will return 1 (on failure), and the caller (ie disk_image) will check the return code and do the appropriate cleanup. Moreover, 'set -e' cannot be relied upon to terminate the script if any function returns error. Thus, it is not very useful.
