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

2019-11-12T22:13:54+00:00

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.

Only if no partition table exists, check for a file system on disk level.

efi_loader: disk: install FILE_SYSTEM_PROTOCOL only if available

2019-10-17T17:19:56+00:00

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.

efi_loader: EFI_BLOCK_IO_PROTOCOL.Reset()

2019-09-05T21:18:51+00:00

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.

efi_loader: use EFI_PRINT() instead of debug()

2019-09-05T21:18:51+00:00

EFI_PRINT() offers indention of debug messages. Adjust the debug messages
of the BLOCK_IO_PROTOCOL.

efi_loader: parameter checks BLOCK_IO_PROTOCOL

2019-09-05T21:18:51+00:00

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.

efi_loader: consistent naming of protocol GUIDs

2019-04-22T22:37:27+00:00

We should consistently use the same name for protocol GUIDs as defined in
the UEFI specification. Not adhering to this rule has led to duplicate
definitions for the EFI_LOADED_IMAGE_PROTOCOL_GUID.

Adjust misnamed protocol GUIDs.

Adjust the text for the graphics output protocol in the output of the
`efidebug dh` command.

efi_loader: eliminate handle member

2018-12-02T20:59:36+00:00

A pointer to a struct efi_object is a handle. We do not need any handle
member in this structure. Let's eliminate it.
