2019-05-07efi_loader: signature of ExitBootServices()Heinrich Schuchardt1-1/+2
Consistently use efi_uintn_t as type of memory keys. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Alexander Graf <graf@amazon.com>

Implement the UnloadImage() boot service Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-04-23efi_loader: consistent naming of protocol GUIDsHeinrich Schuchardt1-11/+7
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. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-04-07efi_loader: boottime: add loaded image device path protocol to image handleAKASHI Takahiro1-0/+4
To meet UEFI spec v2.7a section 9.2, we should add EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL to image handle, instead of EFI_DEVICE_PATH_PROTOCOL. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-03-27efi_loader: TODO for the EFI file protocolHeinrich Schuchardt1-1/+7
We currently only support EFI_FILE_PROTOCOL_REVISION while UEFI specs 2.4 - 2.7 prescribe EFI_FILE_PROTOCOL_REVISION2. Add a todo. Add missing constants for the EFI file protocol revision. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-02-13efi: hii: add keyboard layout package supportAKASHI Takahiro1-0/+6
Allow for handling keyboard layout package in HII database protocol. A package can be added or deleted in HII database protocol, but we don't set 'current' keyboard layout as there is no driver that requests a keyboard layout.

This patch provides enough implementation of the following protocols to run EDKII's Shell.efi and UEFI SCT: * EfiHiiDatabaseProtocol * EfiHiiStringProtocol Not implemented are: * ExportPackageLists() * RegisterPackageNotify()/UnregisterPackageNotify() * SetKeyboardLayout() (i.e. *current* keyboard layout) HII database protocol in this patch series can handle only: * GUID package * string package * keyboard layout package (The other packages, except Device path package, will be necessary for interactive and graphical UI.)

2019-02-13efi_loader: use u16* for file nameHeinrich Schuchardt1-1/+1
UTF-16 strings in our code should all be u16 *. Fix an inconsistency for file names which may lead to a warning for printf("%ls", ). Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2019-02-13efi_loader: efi_set_variable use const void *Heinrich Schuchardt1-1/+2
The SetVariable() runtime service does not change the data passed to it. So mark the parameter as constant. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2019-02-13efi_loader: use const efi_guid_t * for variable servicesHeinrich Schuchardt1-3/+5
The runtime variable services never change GUIDs. So we should declare the GUID parameters as constant. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2019-02-13efi_loader: signature of StartImage and ExitHeinrich Schuchardt1-3/+3

2019-02-13efi_loader: struct efi_configuration_tableHeinrich Schuchardt1-1/+1
Commit 393fccdf6c73 ("efi_loader: efi_guid_t must be 64-bit aligned") has changed the alignment of efi_guid_t. This changed the size of struct efi_configuration_table on 32-bit systems form 20 to 24 bytes. As an array of this type is pointed to by the system table this breaks compatibility with existing versions of GRUB and Linux. Let's get back the original size by using the attribute __packed.

2018-12-02efi_loader: typedef struct efi_object *efi_handle_tHeinrich Schuchardt1-4/+4
All our handles point to a struct efi_object. So let's define the efi_handle_t accordingly. This helps us to discover coding errors much more easily. This becomes evident by the corrections to the usage of handles in this patch. Rename variable image_handle to image_obj where applicable.

2018-10-16efi_loader: correct signature of GetPosition, SetPositionHeinrich Schuchardt1-2/+2
The UEFI spec requires that file positions are passed as u64 in GetPosition() and SetPosition(). Check if the file handle points to a directory in GetPosition(). Provide a unit test for GetPosition() and SetPosition(). Fix Coverity warning CID 184079 (CONSTANT_EXPRESSION_RESULT). Add comments.

2018-09-23efi_loader: refactor efi_setup_loaded_image()Heinrich Schuchardt1-8/+0
Create the handle of loaded images and the EFI_LOADED_IMAGE_PROTOCOL inside efi_setup_loaded_image(). Do not use local variables. Currently we expect the loaded image handle to point to the loaded image protocol. Additionally we have appended private fields to the protocol. With the patch the handle points to a loaded image object and the private fields are added here. This matches how we handle the net and the gop object.
