From b5445ade38e5129ee19ddd97f4b3687fa28afd4b Mon Sep 17 00:00:00 2001 From: Tarun Tuli Date: Fri, 6 Jan 2023 20:49:37 +0000 Subject: mb/google/brya: Increase Resizable BAR address space limit to 33 bits The dGPU used for some Brya projects requests 33 bits of address space for one of its BARs via the Resizable BAR mechanism (requires 6GB). This Kconfig is currently set at 32 bits for brya, so the allocation currently is capped at 32 bits (4GB). This patch sets the limit to 33 bits for brya boards, which is enough for the GPU. BUG=b:214443809 TEST=all of the dGPU PCI BARs on agah can be successfully allocated Change-Id: Ia791be5108fb07a256ae62fc2aee2f057909ef12 Signed-off-by: Tarun Tuli Reviewed-on: https://review.coreboot.org/c/coreboot/+/71282 Tested-by: build bot (Jenkins) Reviewed-by: Subrata Banik --- src/mainboard/google/brya/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/mainboard') diff --git a/src/mainboard/google/brya/Kconfig b/src/mainboard/google/brya/Kconfig index b7a44c7f38..5429d595cd 100644 --- a/src/mainboard/google/brya/Kconfig +++ b/src/mainboard/google/brya/Kconfig @@ -334,6 +334,6 @@ config INCLUDE_NVIDIA_GPU_ASL config PCIEXP_DEFAULT_MAX_RESIZABLE_BAR_BITS int - default 32 + default 33 endif # BOARD_GOOGLE_BRYA_COMMON -- cgit v1.2.3
