Hi Narinder,
Inside Linaro we do not have access to an ARM64 platform which has PCI drivers available so we have never tried.
Al might have some different info from Redhats perspective.
Did you solve the issue you originally had?

Thanx Al. On another note. Do we have support for parsing PCIe root bridges for ARM64 ? I am trying to add PCIe root bridge to DSDT and osl.c is calling 'pci_acpi_scan_root'. I can see there is code in ia64/kernel/pci.c but no corresponding file in arm64. Thanx.

But, Graeme is essentially correct: either secondary CPU startup is happening, or something gets stuck during device probe before printk can report it. At this stage, the only secondary CPU boot protocol supported is via PSCI; there is a parking protocol also but that's still being implemented. You could use the spin-table protocol but I would not recommend it -- it *will* go away and very soon.On Thu, Sep 04, 2014 at 03:44:21PM -0700, Narinder Dhillon wrote:
Hi All, I am booting latest LEG kernel from UEFI that has ACPI tables for
ARMv8
core. ACPI tables are parsed but kernel stops at a certain point
in the
boot cycle and I am not sure where and why. In particular, this statement seems odd because it should not be looking for device tree at all. No CPU information found in DT Kernel console output pasted below. Any help would be
appreciated.
