I will be off the radar till -rc3 but I do not expect major changes to the series in its current form given that dependencies were merged in the merge window (ACPI IRQ probe deferral and IORT fixes).

What's your opinion on this patch set? especially for the last 3 patches for mbigen driver, please comment on it to see if I need to take further steps.

From: Hanjun Guo <hanjun.guo@linaro.org> With platform msi support landed in the kernel, and the introduction of IORT for GICv3 ITS (PCI MSI) and SMMU, the framework for platform msi is ready, this patch set add few patches to enable the ACPI platform msi support. For platform device connecting to ITS on arm platform, we have IORT table with the named componant node to describe the mappings of paltform device and ITS, so we can retrieve the dev id and find its parent irqdomain (ITS) from IORT table (simlar with the ACPI ITS support). v8 -> v9: - Rebased on top of 4.11-rc1 and retest; - Some of patch's commit message was updated by Lorenzo and it's clearer (thanks!) No update in the code, hope it's the final revision. v7 -> v8: - Using _CRS instead of _PRS for Interrupt resources for mbigen - reshuffle the patch slightly to introduce iort_node_map_platform_id() first and then retrieve the dev id for platform MSI, no functional change - Fix the compile error with patch "irqchip: gicv3-its: platform-msi: scan MADT to create platform msi domain", which forgot to add <include/acpi_iort.h> (added in later patches in last version). - renew some commit message which suggested by Lorenzo - address some othe minor issues which commented by Lorenzo - Add review and test tag as it's no functional change except the last patch of mbigen - rebase on top of 4.10-rc4 and test it on x86, ia64 and ARM64 platforms (also with Agustin's patch [1-2/3] "[PATCH V9 0/3] irqchip: qcom: Add IRQ combiner driver" and Lorenzo's patch https://patchwork.kernel.org/patch/9507041/) v6 -> v7: - Introduce iort_node_map_platform_id() to retrieve the dev id for both NC (named component) -> ITS/SMMU and NC -> SMMU -> ITS cases, suggested by Lorenzo; - Reorder the patches and rewrite some commit message; - Remove the test tags because it has major changes to retrieve the dev id, Sinan, Majun, Xinwei, could you please test them again on your platform? - rebased on top of 4.10-rc3 and Lorenzo's patch https://patchwork.kernel.org/patch/9507041/ - Tested against Agustin's patch [1-2/3] "[PATCH V9 0/3] irqchip: qcom: Add IRQ combiner driver" v5 -> v6: - Call acpi_configure_pmsi_domain() for platform devices in acpi_platform_notify() as it's cleaner (suggested by Rafael) - Remove the "u8 type" for iort_id_map() because it's unused - Rebase on top of 4.10-rc2 - Collect test and review tags v4 -> v5: - Add mbigen support back with tested on with Agustin's patchset, and it's a good example of how ACPI platform MSI works - rebased on top of lastest Linus tree (commit 52bce91 splice: reinstate SIGPIPE/EPIPE handling) v3 -> v4: - Drop mbi-gen patches to just submit platform msi support because will rebase mbi-gen patches on top of Agustin's patchset, and discusion is going there. - Add a patch to support device topology such as NC(named componant, paltform device) ->SMMU->ITS which suggested by Lorenzo; - rebased on top of Lorenzo's v9 of ACPI IORT ARM SMMU support; - rebased on top of 4.9-rc7 v2 -> v3: - Drop RFC tag - Rebase against v4.9-rc2 and Lorenzo's v6 of ACPI IORT ARM SMMU support [1] - Add 3 cleanup patches (patch 1, 2, 3) - Drop arch_init call patch from last version - Introduce a callback for platform device to set msi domain - Introduce a new API to get paltform device's domain instead of reusing the PCI one in previous version - Add a patch to rework iort_node_get_id() [1]: http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1251993.html v1 -> v2: - Fix the bug of if multi Interrupt() resoures in single _PRS, we need to calculate all the irq numbers (I missed it in previous version); - Rebased on Marc's irq/irqchip-4.9 branch and Lorenzo's v5 SMMU patches (also Robin's SMMu patches) - Add patch irqchip: mbigen: promote mbigen init.
