* ArmPkg: Fix Ecc error 8003Pierre Gondois2021-04-281-3/+3
| | | | | | | | | | | | | | | | | | This patch fixes the following Ecc reported error: The #ifndef at the start of an include file should have one postfix underscore, and no prefix underscore character Some include guards have been modified to match the name of the header file. Some comments have also been added on the closing '#endif'.

* ArmPkg/Gic: force GIC driver to run before CPU arch protocol driverArd Biesheuvel2018-02-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Currently, the GIC driver has a static dependency on the CPU arch protocol driver, so it can register its IRQ handler at init time. This means there is a window between dispatch of the CPU driver and dispatch of the GIC driver where any unexpected GIC state may trigger an interrupt which we are not set up to handle yet. Note that this is even the case if we enter UEFI with interrupts disabled at the CPU, given that any TPL manipulation involving TPL_HIGH_LEVEL will unconditionally enable IRQs at the CPU side regardless of whether they were enabled to begin with (but only as soon as the CPU arch protocol is actually installed) So let's reorder the GIC driver with the CPU driver, and let it run its initialization that puts the GIC into a known state before enabling interrupts. Move its installation of its IRQ handler to a protocol notify callback on the CPU arch protocol so that it runs as soon as it becomes available.

* ArmPkg/ArmGicDxe: Expose HardwareInterrupt2 protocolArd Biesheuvel2017-10-051-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | The existing HardwareInterrupt protocol lacked a means to configure the level/edge properties of an interrupt. The new HardwareInterrupt2 protocol introduced this capability. This patch updates the GIC drivers to provide the new interfaces. The changes comprise: Update to use HardwareInterrupt2 protocol Additions to register info in ArmGicLib.h Added new functionality (GetTriggerType and SetTriggerType) The requirement for this change derives from a problem detected on ARM Juno boards, but the change is of generic (ARM) relevance. This commit is in response to review on the mailing list and, as suggested there, rolls Girish's updates onto Ard's original example.

* ArmPkg: Tidy GIC code before changes.Evan Lloyd2017-10-051-7/+1
| | | | | | | | | | | | | | | | | | | This change is purely cosmetic, to tidy some code before change. Mods involve: Re-order #includes Reformat comments. Use ns consistently (always "100ns" not sometimes "100 nS") Split overlength code lines. Make protocol functions STATIC. Remove "Horor vacui" comments. Rationalize GIC register address calculations Replace explicit test and assert with ASSERT_EFI_ERROR.
