2019-07-16efi_loader: efi_set_virtual_address_map_runtime()Heinrich Schuchardt
efi_set_virtual_address_map_runtime() must be of type __efi_runtime. Fixes: ee8ebaaaaedc ("efi_loader: split off detaching SetVirtualAddress()") Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-07-06efi_loader: detach runtime in ExitBootServices()Heinrich Schuchardt
Linux can be called with a command line parameter efi=novamap, cf. commit 4e46c2a95621 ("efi/arm/arm64: Allow SetVirtualAddressMap() to be omitted"). In this case SetVirtualAddressMap() is not called after ExitBootServices(). OpenBSD 32bit does not call SetVirtualAddressMap() either. Runtime services must be set to an implementation supported at runtime in ExitBootServices().

2019-07-06efi_loader: simplify detachingHeinrich Schuchardt
We do not need any array typed detach list. Let's simply update the pointers directly. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-07-06efi_loader: decision on EFI_RT_SUPPORTED_RESET_SYSTEMHeinrich Schuchardt
Move the logic determining which board supports reset at runtime to Kconfig. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-07-06efi_loader: split off detaching SetVirtualAddress()Heinrich Schuchardt
The runtime services SetVirtualAddress() and ConvertPointer() become unavailable after SetVirtualAddress(). Other runtime services become unavailable after ExitBootServices. Move the update of SetVirtualAddress() and ConvertPointer() to efi_relocate_runtime_table(). Use functions with the correct signature when detaching. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-07-06efi_loader: unimplemented runtime servicesHeinrich Schuchardt
Unimplemented runtime services should always return EFI_UNSUPPORTED as described in the UEFI 2.8 spec. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-07-06efi_loader: let the variable driver patch out the runtimeHeinrich Schuchardt
Our variable services are only provided at boottime. Therefore when leaving boottime the variable function are replaced by dummy functions returning EFI_UNSUPPORTED. Move this patching of the runtime table to the variable services implementation. Executed it in ExitBootServices(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-07-06efi_loader: clean up runtime detachingHeinrich Schuchardt
The detaching of the runtime will have to move to ExitBootServices() to encompass operating system that do not call SetVirtualAddressMap(). This patch changes the logic for the relocation of the pointers in the runtime table such that the relocation becomes independent of the entries in the detach list. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-07-06efi_loader: remove NULL entries from runtime detach listHeinrich Schuchardt
Some entries in the system table are set to NULL in ExitBootServices(). We had them in the runtime detach list to avoid relocation of NULL. Let's instead assign the pointers dynamically in efi_initialize_system_table() to avoid the relocation entry. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-07-06efi_loader: initialization of variable servicesHeinrich Schuchardt
Provide an initialization routine for variable services. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-06-20efi_loader: ListPackageLists() return EFI_NOT_FOUNDHeinrich Schuchardt
If no matching package list is found in ListPackageLists(), return EFI_NOT_FOUND. If we do not support a package type, we will not find a matching package list. Remove the unreachable EFI_PRINTF() statements. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-20efi_loader: console incorrectly advertised left logo keyHeinrich Schuchardt

2019-06-14efi_loader: add RuntimeServicesSupported variableAKASHI Takahiro
This variable is defined in UEFI specification 2.8, section 8.1. Its value should be updated whenever we add any usable runtime services function.

2019-06-14efi_loader: legal characters in StrToFat()Heinrich Schuchardt
The UEFI specification does not specify if the characters that have to be replaced by underscore in function StrToFat() of the Unicode collation protocol are those forbidden in FAT long names or those in FAT short names. EDK2 and UEFI SCT assume it is those forbidden in FAT 8.3 short names. Adjust the list of forbidden characters. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2019-06-10efi_loader: implement event queueHeinrich Schuchardt
Up to now we have only been using a flag queued for events. But this does not satisfy the requirements of the UEFI spec. Events must be notified in the sequence of decreasing TPL level and within a TPL level in the sequence of signaling. Implement a queue for signaled events. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-06-10efi_loader: event signaling in ExitBootServicesHeinrich Schuchardt
ExitBootServices() has to stop timer related activity before calling the events of the EFI_EVENT_GROUP_EXIT_BOOT_SERVICES event group. But our current implementation was stopping all other events. All events have to observe the task priority level. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
