[linux-yocto][v6.1/standard/x86 and v6.1/standard/preempt-rt/x86][PATCH 0/1] Fix Intel Grand Ridge cannot boot issue

2024-04-23 Thread Yongxin Liu via lists.yoctoproject.org 

Hi Bruce,

Intel Grand Ridge cannot boot after the backport of commit a6a5006dad57
("iommu/vt-d: Retrieve IOMMU perfmon capability information"), in v6.1.83.

This patch is the second patch of the following patch series in mainline.

d8a7c0cf05a2 2023-02-03 11:06 Kan Liangiommu/vt-d: Enable IOMMU perfmon 
support
4a0d4265659b 2023-02-03 11:06 Kan Liangiommu/vt-d: Add IOMMU perfmon 
overflow handler support
46284c6ceb5e 2023-02-03 11:06 Kan Liangiommu/vt-d: Support cpumask for 
IOMMU perfmon
7232ab8b89e9 2023-02-03 11:06 Kan Liangiommu/vt-d: Add IOMMU perfmon 
support
dc57875866ab 2023-02-03 11:06 Kan Liangiommu/vt-d: Support Enhanced 
Command Interface
a6a5006dad57 2023-02-03 11:06 Kan Liangiommu/vt-d: Retrieve IOMMU 
perfmon capability information
4db96bfe9d77 2023-02-03 11:06 Kan Liangiommu/vt-d: Support size of the 
register set in DRHD

It is strange only one patch was backported in linux-stable v6.1.
Because in order to eable IOMMU perfmon, all patches should be backported.

Anyway, we need to back port the first patch to boot kernel on newer hardware, 
such as Intel GrandRidge.

So please help to merge this patch to v6.1/standard/x86 and 
v6.1/standard/preempt-rt/x86.


Thanks,
Yongxin
