Enable KVM by default on Lemans and Monaco Platforms by vkraleti · Pull Request #2251 · qualcomm-linux/meta-qcom

Viswanath Kraleti (vkraleti) · 2026-05-20T09:35:43Z

All PILs are functioning correctly and KVM can be enabled by default on Lemans and Monaco platforms.
Update FIT_DTB_COMPATIBLE entries and machine configurations to switch to default KVM for these boards.

Is lemans-el2 available on linux-yocto?

lemans-el2.dtbo is available from 'v7.0-rc1' onwards. I'll backport the change as a .patch to linux-yocto.

No. Supporting EL2 is not just the DT, it might require driver changes, etc.
We should have all the mechanisms to have DTs supported by qcom-6.18 / qcom-next but not by linux-yocto.

From a kernel build perspective, meta-qcom already supports selecting DTB/DTBOs per kernel. However, the FIT_DTB_COMPATIBLE mapping is common for all. Should we now consider splitting FIT_DTB_COMPATIBLE per kernel? Without doing so, we will not be able to map different DTB/DTBO sets to the same compatible string.

Alternatively, we may need to introduce a new substring, say 'gunyah' so that only the base DTB can selected, without the EL2 DTBO.

I think FIT_DTB_COMPATIBLE should remain common. In the end, the list of the DTBs for each feature should not depend on the kernel version. The list of DTBs available, might, but it's already handled.

What if the user selects el2gh while we flashed xbl_config_kvm?

This can happen even with current implementation. This PR's goal is to switch the default from Gunyah to KVM. IMO, mismatch b/w DTBO and xbl_config needs a separate discussion.

What if the user selects el2gh while we flashed xbl_config_kvm?

We tried on hamoa, if we don't use uefi_dtbs_kvm.xz and el2 dtbo together, there will be bootup issue.

Do we stand a chance of the firmware reporting the selected xbl_config without requiring a manual intervention from the user side?

Current firmware don't have this support. Need to request boot firmware team for this feature.

Using MACHINE_FEATURES for to KVM enablement is now part of #2289. This PR only focuses switching Lemans platforms to default KVM.

This is RFC draft PR to seek inputs on default KVM enablement. I wasn't really expecting test teams monitoring it. There is even a comment saying the PR is broken into two.

Viswanath Kraleti (@vkraleti) both monaco and lemans failed to boot on lava.

Viswanath Kraleti (vkraleti) · 2026-06-04T14:11:01Z

Viswanath Kraleti (@vkraleti) both monaco and lemans failed to boot on lava.

Without qualcomm-linux/meta-qcom-distro#314, kvm is not present in COMBINED_FEATURES.
As a result, Gunyah XBL config is being flashed, but FIT_DTB_COMPATIBLE has already switched to selecting EL2 DTBOs.
This mismatch causes Monaco and Lemans fail to boot.

To resolve this, we have two options:

Eaither merge Make KVM as a default distro feature meta-qcom-distro#314 so that kvm is included in COMBINED_FEATURES, or
As a temporary workaround, set QCOM_XBL_CONFIG only based on MACHINE_FEATURES.

Ricardo Salveti (ricardosalveti) · 2026-06-04T15:22:33Z

2. As a temporary workaround, set QCOM_XBL_CONFIG only based on MACHINE_FEATURES.

Yeah, we could do in 2 steps, first as machine features and later as combined, once merged.

Avoid hardcoding XBL configuration logic in image_types_qcom, which limits flexibility for per-board virtualization control. Define QCOM_XBL_CONFIG in qcom-common.inc to select the appropriate XBL config based on MACHINE_FEATURES. This enables consistent KVM selection while allowing machine-level overrides when required. Signed-off-by: Viswanath Kraleti <viswanath.kraleti@oss.qualcomm.com>

Adjust CI to handle removal of qcom-distro-kvm configuration in meta-qcom-distro, where KVM is now enabled by default. Replace usage of the qcom-distro-kvm distro with explicit addition of `kvm` to MACHINE_FEATURES to retain KVM-enabled builds during the transition. This is a temporary workaround until CI fully adopts the new KVM-by-default model. Signed-off-by: Viswanath Kraleti <viswanath.kraleti@oss.qualcomm.com>

Thanks for the confirmation. I’ve updated the PR. With this change, all targets should now boot as expected.
