Add basic UEFI loader to lk Thids adds a uefi_load <block dev name> command, which will parse the PE header and do some basic validation checks. Bug: 294283461 Test: uefi_load virtio0 Change-Id: I97393652526bda5be1b995e59647e239c64d31d6 2024-06-07 13:07:03 -07:00			`LOCAL_DIR := $(GET_LOCAL_DIR)`

[app][uefi] Enable mspace feature on dlmalloc This allows us to use an identitiy mapped piece of memory as the heap for UEFI app. UEFI app's allocation would go from this heap. 2024-10-08 10:38:02 -07:00			`MODULE_DEFINES=MSPACES=1`

[lib][uefi] Default implementation of BootService.SetWatchdogTimer() The platform_watchdog_ methods are optional features that the target platform can choose to implement. If they are implemented, then BootService.SetWatchdogTimer() would call them to setup the hardware watchdog. If they are not implemented (for example presubmit targets), then BootService.SetWatchdogTimer() would test the WEAK symbol against a NULL pointer and error out. To use BootService.SetWatchdogTimer(), platforms can choose to either implement platform_watchdog_init and platform_watchdog_set_enabled, or override the entire BootService.SetWatchdogTimer() method. 2025-08-08 15:20:04 +08:00			`MODULE_INCLUDES += \`

[lib][uefi] Implement events API in UEFI LK already has events APIs. To support events protocols in UEFI spec, I created a wrapper object for LK events. This wrapper object keeps additional data that are necessary to support UEFI events spec: * Notification function, or callbacks * Argument for the notification function * Type of this UEFI event (which specifies when the callback should be called) The events API is essential for supporting async I/O in UEFI. Intended use case looks like: * UEFI app creates an event object, attatch callback to this event * UEFI app calls LK for asynchronous read/write on a block device, with the newly created events object * LK executes IO operation in background, after IO finishes, signal the specified event object * UEFI's callback gets executed 2025-07-14 12:19:51 -07:00			`$(LOCAL_DIR)/events.cpp \`

lib: uefi: add EfiSystemTablePointer for debug Add EfiSystemTablePointer structure for remote debugger to locate the address of EfiSystemTable. This feature is described in UEFI SPEC version 2.10. Section 18.4.2. The implementation ensures support for hardware-assisted debugging and provides a standardized mechanism for debuggers to discover the EFI system table.

lib: uefi: add volatile UEFI variable support GBL needs to read an UEFI variable called "gbl_debug". We add 2 commands. "uefi_set_var" to set an UEFI variable. And "uefi_list_var" to list the UEFI variables. For GBL, we can use "uefi_set_var gbl_debug 1" to enable its debug mode.
