sandbox: Add more dummy cache functions

2025-10-08T22:12:46Z

In order for cmd/cache.c to link we need to add dummy icache functions to mirror the dummy dcache functions as well as another dcache flush function. Signed-off-by: Tom Rini

sandbox: use env_get() for time offset instead of getenv()

2025-09-24T17:03:24Z

The sandbox time offset is intended to be controlled via the U-Boot environment, not the host process environment. Update os_get_time_offset() to use env_get() instead of the libc getenv(). Leave other getenv() uses (e.g. U_BOOT_PERSISTENT_DATA_DIR, UBOOT_SB_FUZZ_TEST) unchanged, since those refer to host environment variables needed by sandbox tests. Signed-off-by: Osama Abdelkader

Revert "sandbox: replace deprecated getenv() with env_get()"

2025-09-12T22:57:39Z

While testing changes, I missed that Gitlab had failed CI with pytest failures due to this change. This reverts commit 4c822970d366415e717730606734e815993a70bb. Cc: Osama Abdelkader Signed-off-by: Tom Rini

Merge patch series "sandbox: align LMB memory"

2025-06-26T19:45:43Z

Heinrich Schuchardt says: To implement the EFI_SYSTEM_TABLE_POINTER we need 4 MiB aligned memory. On the sandbox LMB uses addresses relative to the start of a page aligned RAM buffer allocated with mmap(). This leads to a mismatch of alignment between EFI which uses pointers and LMB which uses phys_addr_t. Ensure that the RAM buffer used for LMB is 4 MiB aligned. Provide a unit test for efi_alloc_aligned_pages() verifying this alignment. Do not overwrite RAM size in dram_init().

spl: Rename jump_to_image_no_args()

2025-06-13T19:22:53Z

This function is currently a misnomer at times as we have cases where it passes arguments to the image. In preparation for making that be a more common case rename this function to jump_to_image(...). In order to do this, rename jump_to_image in board_init_r(...) to jumper so that we do not have a conflict.

sandbox: add initjmp()

2025-04-23T19:19:44Z

Add initjm[() to sandbox, a non-standard extension to setjmp()/ longjmp() allowing to initialize a jump buffer with a function pointer and a stack pointer. This will be useful to later introduce threads. With this new function it becomes possible to longjmp() to a particular function pointer (rather than to a point previously reached during program execution as is the case with setjmp()), and with a custom stack. Both things are needed to spin off a new thread. Then the usual setjmp()/longjmp() pair is enough to save and restore a context, i.e., switch thread. The implementation is taken verbatim from barebox [1] with the exception of the additional stack_sz argument. It is quite complex because contrary to U-Boot platform code we don't know how the system's C library implements the jump buffer, so we can't just write the function and stack pointers into it.

common: clean up setjmp.h

2025-03-10T06:41:16Z

Separate setjmp.h into an architecture independent part and an architecture specific part. This simplifies moving from using struct jmp_buf_data directly to using type jmp_buf in our code which is the C compliant way. Reviewed-by: Jerome Forissier Signed-off-by: Heinrich Schuchardt

test: Move stat-printing into its own function

2025-01-24T20:34:41Z

Add a function to show the stats, so we can decide when to print it. This slightly adjusts the output, so that any 'test not found' message appears on its own line after all other output. The 'failures' message now appears in lower case so update pytest accordingly. Signed-off-by: Simon Glass
