* Add support for cache coloringStefano Stabellini2022-06-172-1/+35
| | | | | | | | | | | Generate the coloring information for Xen, dom0 and domUs based on information on the config file. Cache coloring is not upstreaming but it was published to xen-devel already. It is very useful to be able to provide a cache coloring configuration via config file instead of manually editing boot.source. Signed-off-by: Stefano Stabellini <stefano.stabellini@xilinx.com>
* uboot-script-gen: Add DOMU_STATIC_MEMXenia Ragiadakou2022-06-162-2/+65
| | | | | | | | | | | | | | | | | | | | | Add a new config parameter to configure a dom0less VM with static allocation. DOMU_STATIC_MEM[number]="baseaddr1 size1 ... baseaddrN sizeN" The parameter specifies the host physical address regions to be statically allocated to the VM. Each region is defined by its start address and size. 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.

* Generate the domU partial dtb via disk_imageAyan Kumar Halder2021-12-211-12/+45
| | | | | | | | | | | | | | | | | | | | Similar to uboot-script-gen, disk_image invokes compile_merge_partial_dts to generate the domU partial dtbs. It copies the dtbs to /etc/xen. Added functions to cleanup the temporary files. Also removed 'set -e'. This was causing the script to terminate if any of the functions returned non zero. 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.

* Avoid exiting the script from the commonAyan Kumar Halder2021-12-212-25/+36
| | | | | | | | | | | | | | | | | | | | | | | If there is any error in compile_merge_partial_dts() and sanity_check_partial_dts(), it should return 1 to the caller. The caller will then check the return and call cleanup_and_return_err() (which terminates the script). This is to prevent compile_merge_partial_dts() and sanity_check_partial_dts() terminating the script. The reason being these functions can get invoked from disk_image (in the future) which may require some additional cleanup. Also, moved cleanup_and_return_err() to uboot-script-gen as the cleanup is specific to the script. Ensure that we preseve the directory containing the partial dtbs only when the dtbs were generated successfully. Else, we delete it.

| | | | | | | | | | | | | | One should copy the device tree to a temporary file and then make any change (so as to enable merging of multiple device trees). In this case, the change is to remove the marker (/dts-v1/;) from all the device trees except the first one to be merged. DTC expects the marker to be present only once. Also, i, j, tmpdts and file should be set to local. This will avoid name collision.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | One can specify the repository and the directory holding the partial device trees via the config option PASSTHROUGH_DTS_REPO. This can be either a git url or a local directory containing the partial device trees. Also, the passthrough devices for each DOMU are specified via DOMU_PASSTHROUGH_PATHS config option. Imagebuilder will compile the partial device trees. The underlying assumption is that the name of the partial device tree should match to the name of the device specified in DOMU_PASSTHROUGH_PATHS. For example (in case of git repo) :- PASSTHROUGH_DTS_REPO="git@github.com:Xilinx/xen-passthrough-device-trees.git device-trees-2021.2" DOMU_PASSTHROUGH_PATHS[0]="/axi/serial@ff010000 /axi/mmc@ff170000" (This tells imagebuilder to clone the repo and use serial@ff010000.dts and mmc@ff170000.dts from device-trees-2021.2 folder, to compile and generate a partial dtb for DOMU[0].

| | | | | | | | | | | | A heuristic was used in the previous implementation for simplicity (*2) but when using bigger file systems size overflows.
