Re: [edk2-devel] [edk2-platforms: PATCH v2] Marvell/Armada7k8k: Introduce SMBIOS/DMI support

["Marcin Wojtas" <mw@semihalf.com>]

Hi Jeremy,

Thanks for a quick test!

1. Cache sizes - here's the dmidecode output

Handle 0x1000, DMI type 7, 27 bytes
Cache Information
Socket Designation: L1 Instruction
[...]
Installed Size: 48 kB
[...]

Handle 0x1001, DMI type 7, 27 bytes
Cache Information
Socket Designation: L1 Data
[...]
Installed Size: 32 kB
Maximum Size: 32 kB
[...]

Handle 0x1002, DMI type 7, 27 bytes
Cache Information
Socket Designation: L2
[...]
Installed Size: 512 kB
Maximum Size: 512 kB
[...]

Handle 0x1003, DMI type 7, 27 bytes
Cache Information
Socket Designation: L3
[...]
Installed Size: 1024 kB
Maximum Size: 1024 kB
[...]

Above size values match the spec. Am I missing something?

2. DIMM/SPD data is read and processed in ARM-TF. Currently processing this
data is not available in EDK2. On the other hand Table19 and TYPE 17 shows
the real memory map and size, which is read during EDK2 init (check
GetDramSize ()
in Silicon/Marvell/Armada7k8k/Library/Armada7k8kLib/Armada7k8kLibMem.c)
from via SMC from the secure world.

DDR speed is also read from the SoC registers.

Any particular data that you are missing?

3. In next step I'd like to use BoardDescProtocol to update a couple of
tables fields such as name, revision number, PCIE slots information.

Best regards,
Marcin
