efi_loader: fix GetInfo and SetInfo

2024-11-01T19:37:58Z

* Some of our file system drivers cannot report a file size for directories. Use a dummy value in this case. * For SetInfo the UEFI spec requires to ignore the file size field. Signed-off-by: Heinrich Schuchardt Reviewed-by: Ilias Apalodimas Reviewed-by: Simon Glass

efi_loader: Remove

2023-12-21T13:54:37Z

We largely do not need in these files, so drop it. The only exception here is that efi_freestanding.c needs and had been getting that via . Reviewed-by: Simon Glass Signed-off-by: Tom Rini

efi_loader: error handling in efi_disk_add_dev

2023-08-03T07:21:03Z

* If an error occurs in efi_disk_add_dev(), don't leak resources. * If calloc() fails while creating the file system protocol interface, signal an error. * Rename efi_simple_file_system() to efi_create_simple_file_system(). * Drop a little helpful debug message.

efi_loader: replace a u16_strdup with alloc + memcpy

2022-11-16T07:34:06Z

Heinrich reports that on RISC-V unaligned access is emulated by OpenSBI which is very slow. Performance wise it's better if we skip the calls to u16_strdup() -- which in turn calls u16_strsize() and just allocate/copy the memory directly. The access to dp.length may still be unaligned, but that's way less than what u16_strsize() would do Signed-off-by: Ilias Apalodimas Use malloc() instead of calloc().

efi_loader: add missing EFI_CALL when closing a file

2022-11-16T07:34:06Z

Closing the files uses the EFI protocol and specifically it's .close callback. This needs to be wrapped on an EFI_CALL() Signed-off-by: Ilias Apalodimas Reviewed-by: Heinrich Schuchardt

efi_loader: add comments on efi_file_from_path() regarding alignment

2022-11-16T07:34:06Z

UEFI specification requires pointers that are passed to protocol member functions to be aligned. There's a u16_strdup in that function which doesn't make sense otherwise Add a comment so no one removes it accidentally Signed-off-by: Ilias Apalodimas Reviewed-by: Heinrich Schuchardt
