Re: [PATCH 08/10] OvmfPkg: Update Sec to support Tdvf Config-B

Hi, Yes, I think we need a PlatformLib for the platform initialization code. With PEI we would simply link the lib into PlatformPei, without PEI we would link parts of the lib into SEC and parts of

Re: [PATCH] Update Graphics Info Hob FrameBufferSize Based on UEFI Spec 2.0

Hi., Michael The issue was coming due to assign UINTN to UINT32 (warning C4244: '=': conversion from 'UINTN' to 'UINT32', possible loss of data) I will fix this in my code instead of changing in

Re: [PATCH] Update Graphics Info Hob FrameBufferSize Based on UEFI Spec 2.0

Hi Ashraf, HOBs must never use UINTN or pointer fields. HOBs must always be the same size no matter what CPU or CPU mode the structure is compiler for. This is also a non-backwards compatible

[PATCH V2 10/10] Platform/RaspberryPi: Update RPi4 Readme

Replace the paragraph about NVRAM/UEFI variables, with something that explains the situation a bit better. Update the UEFI settings table. Tweak the DT overlay list, and note support for CM4 and

[PATCH V2 09/10] Platform/RaspberryPi: Add SPI flash variable store.

The RPi4 has a 512KB SPI flash, which depending on RPi and firmware revision has 300-180K free. We can use this storage to persist variables when the OS is running or over firmware upgrades. The

[PATCH V2 08/10] Platform/RaspberryPi: Allow pin function selection at runtime

Update GpioLib slightly so that we can change the GPIO pin muxing at runtime. For the moment only the GpioPinFuncGet/Set() routines are used at runtime, and only by the Variable service. Tested-by:

[PATCH V2 07/10] Platform/RaspberryPi: Add SPI/GPIO to memory map

A large reason for using the SPI flash on this platform is that it can be updated without OS interference at rutime. In order for that to happen we need both the SPI, as well as the GPIO which is used

[PATCH V2 06/10] Platform/RaspberryPi: Add mailbox cmd to control audio amp

The lower level firmware can enable/disable a LDO audio amp, which allows us to mute/unmute audio output while the firmware is running. Tested-by: Ard Biesheuvel <ardb@...> Signed-off-by:

[PATCH V2 04/10] Platform/RaspberryPi: Add menu item to enable/disable GPIO

Now that the GPIO devices are in their own SSDT lets add a menu item for the rpi4 to enable/disable it. For the rpi3 the SSDT is always exported. Tested-by: Ard Biesheuvel

[PATCH V2 03/10] Platform/RaspberryPi: Move GPIO/SPI/I2C to SSDT

The UEFI firmware uses the GPIO port for the fan and real soon now the runtime SPI variable store. As such we need to be able to either isolate those devices from the OS or we risk clashing with OS's

[PATCH V2 02/10] Platform/RaspberryPi: Give the user control over the XHCI mailbox

Its a complete tossup whether removing the mailbox call after we have set up the XHCI works for a given kernel+distro in DT mode. So lets give users which want to try DT the option of flipping this

[PATCH V2 00/10] Platform/RaspberryPi: Utilize SPI flash for EFI variables

The RPi4 has a SPI flash with unused capacity. This set detects if that capacity is sufficient for a UEFI variable store and utilizes it as such. This fixes a long list of problems, and along the way

[PATCH V2 01/10] Platform/RaspberryPi: Cleanup menu visibility

Lets allow some of these options to change when the system is in ACPI+DT mode. Plus the fan temp should be disabled when ACPI isn't enabled. Tested-by: Ard Biesheuvel <ardb@...> Signed-off-by:

Re: [PATCH] Update FvLength to UINTN from UINT32 in FirmwareVolumeInfo

Ashraf, Changing the PPI .h files makes it incompatible with the PI Specification. What is wrong with the max size of a FV being 32-bits (4GB)? Is there a use case for FVs larger than 4GB? I agree
