[Xen-devel] [TESTDAY] Test report

["Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxx>]

* Hardware: ZCU102 ZynqMP board
* Software: Rolled my own dom0 linux
* Tested: Start dom0

The test fails with the following error:
(XEN) I/O virtualisation enabled
(XEN)  - Dom0 mode: Relaxed
(XEN) Interrupt remapping enabled
(XEN) *** LOADING DOMAIN 0 ***
(XEN) Loading kernel from boot module @ 0000000000080000
(XEN) Allocating 1:1 mappings totalling 512MB for dom0:
(XEN) BANK[0] 0x00000020000000-0x00000040000000 (512MB)
(XEN) Grant table range: 0x0000007fe00000-0x0000007fe5f000
(XEN) smmu: /amba/smmu@fd800000: d0: p2maddr 0x000000007ff64000
(XEN) Device tree generation failed (-22).

It's the PCIe node that is causing trouble, the bindings are here:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/pci/xilinx-nwl-pcie.txt

It's that inner interrupt-controller node that is causing problems as
Xen/ARM only supports one interrupt-controller node (IIUC).

Disabling the pcie node for zynqmp boards gets dom0 to boot (obviously
without PCIe support).

Does it make sense to try to fix this problem this late inte the
release cycle? (I can have a closer look and propose a possible fix
for discussion)

Or should we disable the PCIe for ZynqMP for now and try to fix this
properly for 4.8?

Any ideas/suggestions?

Best regards,
Edgar
