Hey all,
I discovered today that there's a new replacement for memtest86+ that appears to even have UEFI support called PCMemTest[0].
The main reason I call out to this is because we don't have a memory tester offering in our UEFI boot variant for the Fedora live media, and this is actively maintained (unlike memtest86+, which we currently use...).
Mageia is shipping this starting with Mageia 8[1], and we should consider shipping this with Fedora 34.
* A listed limitation: "When booted on a UEFI system, keyboard input will only be seen if the CSM is enabled in the BIOS. Without this, the test will run, but you will be unable to alter the configuration."
- How does a CSM provide keyboard input to an EFI application? Or does this mean with CSM enabled, we'd use the BIOS version of the memory tester; and with CSM disabled, we'd use the UEFI version of the memory tester?
- As far as I'm aware, enabling CSM requires disabling UEFI Secure Boot.
* Any UEFI memory tester needs to be signed with Fedora's signing key, same as grubx64.efi so that it works with UEFI Secure boot enabled.
