efi_loader: disk: add efi_disk_is_system_part()

2020-05-04T10:26:11Z

This function will check if a given handle to device is an EFI system partition. It will be utilised in implementing capsule-on-disk feature. Signed-off-by: AKASHI Takahiro Add function description. Return bool. Reviewed-off-by: Heinrich Schuchardt

efi_loader: identify EFI system partition

2020-04-30T08:25:07Z

In subsequent patches UEFI variables shalled be stored on the EFI system partition. Hence we need to identify the EFI system partition. Signed-off-by: Heinrich Schuchardt

efi_loader: simplify logical expression in efi_disk_add_dev()

2020-03-22T10:06:23Z

efi_loader: disk: install file system protocol to a whole disk

2019-11-12T22:13:54Z

Currently, a whole disk without any partitions is not associated with EFI_SIMPLE_FILE_SYSTEM_PROTOCOL. So even if it houses some file system, there is a chance that we may not be able to access it, particularly, when accesses are to be attempted after searching that protocol against a device handle. With this patch, EFI_SIMPLE_FILE_SYSTEM_PROTOCOL is installed to such a disk if part_get_info() shows there is no partition table installed on it. Signed-off-by: AKASHI Takahiro Only if no partition table exists, check for a file system on disk level. Signed-off-by: Heinrich Schuchardt

efi_loader: disk: install FILE_SYSTEM_PROTOCOL only if available

2019-10-17T17:19:56Z

In the current implementation, EFI_SIMPLEFILE_SYSTEM_PROTOCOL is always installed to all the partitions even if some of them may house no file system. With this patch, that protocol will be installed only if any file system exists. Signed-off-by: AKASHI Takahiro Reviewed-by: Heinrich Schuchardt

efi_loader: EFI_BLOCK_IO_PROTOCOL.Reset()

2019-09-05T21:18:51Z

We cannot do anything in EFI_BLOCK_IO_PROTOCOL.Reset() but this does not justify to return an error. Let EFI_BLOCK_IO_PROTOCOL.Reset() return EFI_SUCCESS. Signed-off-by: Heinrich Schuchardt

efi_loader: use EFI_PRINT() instead of debug()

2019-09-05T21:18:51Z

EFI_PRINT() offers indention of debug messages. Adjust the debug messages of the BLOCK_IO_PROTOCOL. Signed-off-by: Heinrich Schuchardt

efi_loader: parameter checks BLOCK_IO_PROTOCOL

2019-09-05T21:18:51Z

Check parameters of ReadBlocks() and WriteBlocks(). If the buffer size is not a multiple of the block size, we have to return EFI_BAD_BUFFER_SIZE. Signed-off-by: Heinrich Schuchardt
