Hi All,

We have populated the new �SystemReady ACS github repo at 
https://github.com/ARM-software/arm-systemready 
.


Specifically, the beta release of the SystemReady IR ACS is now used for 
the SystemReady IR v1.0 certification. See 
https://github.com/ARM-software/arm-systemready/tree/main/IR 
.


We are continuing the restructuring of the ACS. In the meantime, the 
SystemReady SR v2.0 and ES v1.0 certifications are still using 
Enterprise ACS 3.0 at https://github.com/ARM-software/arm-enterprise-acs 
.

Alternatively, you can do the tracing by adding "#define DEBUG" in
efi_boottime.c.
(no way to selectively trace calls, though.)

Yes that does sound like a good thing to have.

Re: RPI4 booting with SystemReady-IR flow

[Bill Mills]

WRT RPI and Uboot.

Ubuntu 20.04 used U-boot on RPI.
Ubuntu 20.10 eliminates it to rely directly on the RPI firmware model so 
USB and ENET boot work.


This is not a good tread direction for our story.  (I have not checked 
21.04.)

Hi,

I verified that RPI4 can boot Ubuntu and LEDGE RP with UEFI + U-Boot.
Two flows have been checked: direct (kernel+initrd in BootXXX variable
leveraging LOAD_FILE2 mechanism) and through grub.

Note: Grub (current head) behaves properly but does not display anything on
serial console because lack of U-Boot (2021.07-rc2) support for:

   GRUB_EFI_SERIAL_IO_GUID \

   { 0xbb25cf6f, 0xf1d4, 0x11d2, \

 { 0x9a, 0x0c, 0x00, 0x90, 0x27, 0x3f, 0xc1, 0xfd } \

   }


/* details: grub-core/term/efi/serial.c, grub_efiserial_init() ->
grub_efi_locate_handle
(GRUB_EFI_BY_PROTOCOL, _io_guid,...) returns NULL */


So I think we need to add this protocol and some others to make the UEFI
text environment fully supported for grub.


Cheers

PS: It would be nice to have an efidebug command to actually trace all boot
services calls to "get_protocol" and either trace all requests or just
failed requests.
