current state of the Seattle topic branch

by Al Stone

Slowly but surely, the Seattle topic branch is coming back to life. I pushed up a version today to acpi.git that has the console working (and earlycon) via SPCR, AHCI works so the SATA drive will come up, and the PMU will start, and the secondary CPUs will come up via the parking protocol. GICv2 support seems to be working. too. I recommend that you have version 73C or 74D firmware; anything earlier is sketchy. This is all in acpi-topic-seattle, which is based on the v9 version of the patches (and hence 4.0-rc1, too). It's enough I can get to a shell prompt/login and do useful things. Things that still need work: -- Reboot doesn't work; there's a patch for this but not applied just yet -- The XGBE NIC is weird. If you have the B0 rev of the board, it may work fine. I have an A0 which requires a slightly different driver that is not working (it causes a hang that I'm trying to figure out); this may just be because of 4.0. -- Need to add in PCI support, plus things like USB, I2C, IPMI, and so on -- all the other stuff currently listed in the DT. There are patches for all of this, but it's a mess because of what we can and cannot release just yet -- and, well, because I find PCI confusing, too :). -- KVM would be good to have (yes, it does need a mod for ACPI). I'd like to at least get PCI working before notifying LKML. Anything you have time to help with is greatly appreciated.... -- ciao, al ----------------------------------- Al Stone Software Engineer Linaro Enterprise Group al.stone(a)linaro.org -----------------------------------

[patch v11 00/23] Introduce ACPI for ARM64 based on ACPI 5.1

by Hanjun Guo

Some fixes since last version: - Add a patch 19/23 for disabling ACPI for Xen on ARM64 for now to fix compile errors on XEN ACPI, Stefano and Julien are ok with this temporary solution. - Add patch "ARM64 / ACPI: Don't unflatten device tree if acpi=force is passed", which will fix the problem that the device tree will be unflattened even if acpi=force passed, that will not obey the policy. - update patch "irqchip: Add GICv2 specific ACPI boot support", which will cause compile error on i386 with both DT and ACPI enabled: All error/warnings: In file included from include/linux/acpi_irq.h:4:0, from drivers/irqchip/irqchip.c:11: arch/x86/include/asm/irq.h:35:8: error: unknown type name 'bool' extern bool handle_irq(unsigned irq, struct pt_regs *regs); ^ arch/x86/include/asm/irq.h:35:45: warning: 'struct pt_regs' declared inside parameter list extern bool handle_irq(unsigned irq, struct pt_regs *regs); ^ arch/x86/include/asm/irq.h:35:45: warning: its scope is only this definition or declaration, which is probably not what you want .... That's because of I include the <asm/irq.h> in <linux/acpi_irq.h>, and <linux/acpi_irq.h> will be put on the top of all head files, so use <linux/irq.h> instead of <asm/irq.h> in acpi_irq.h (in <linux/irq.h>, it will include <linux/*.h> before include <asm/irq.h>), this is the only update for this patch. Lorenzo will send some cleanup patches on top of this one soon.

[V7 PATCH 0/3] Introduce ACPI support for ahci_platform driver

by Suravee Suthikulpanit

This patch series introduce ACPI support for AHCI platform driver. Existing ACPI support for AHCI assumes the device controller is a PCI device. Since there is no ACPI _CID for generic AHCI controller, the driver could not use it for matching devices. Therefore, this patch introduces a mechanism for drivers to match devices using ACPI _CLS method. _CLS contains PCI-defined class-code. This patch series also modifies ACPI modalias to add class-code to the exisiting format, which currently only uses _HID and _CIDs. This is required to support loadable modules w/ _CLS. This is rebased from and tested with: http://git.linaro.org/leg/acpi/acpi.git acpi-5.1-v11 This topic was discussed earlier here (as part of introducing support for AMD Seattle SATA controller): http://marc.info/?l=linux-arm-kernel&m=141083492521584&w=2 Changes from V6 (https://lkml.org/lkml/2015/3/25/797) * Adding Acked-by Mika, and Reviewed-by Hanjun * Minor clen up to use lower case 0xffffff for cls_msk (per Mika suggestions). * Modify the ACPI_DEVICE_CLASS macro to use designated initializer (per Mika suggestions).

This is a large amount of changes, and will be done separtely from this patch series.

Rafael, I assume this patchset will be taken with your tree if it makes sense, any rebase work needed please let me know. the last patch - ACPI / processor: Introduce invalid_phys_cpuid() will cut u64 mpidr to int, but I think it is ok for error values, correct me if I'm wrong.

Therefore, this patch introduces a mechanism for drivers to match devices using ACPI _CLS method. _CLS contains PCI-defined class-code. This patch series also modifies ACPI modalias to add class-code to the exisiting format, which currently only uses _HID and _CIDs. This is required to support loadable modules w/ _CLS. This patch series is rebased from and tested with: http://git.linaro.org/leg/acpi/acpi.git acpi-5.1-v9 This topic was discussed earlier here (as part of introducing support for AMD Seattle SATA controller): http://marc.info/?l=linux-arm-kernel&m=141083492521584&w=2 Changes from V4 (https://lkml.org/lkml/2015/3/2/56) * [1/2] Bug fixed: Reorder the declaration of struct acpi_pnp_device_id cls in the struct acpi_device_info (include/acpi/actypes.h) since compatible_id_list must be last one. * [2/2] Added Acked-by: Tejun Heo <tj(a)kernel.org> Changes from V3 (https://lkml.org/lkml/2015/2/8/106) * Instead of introducing new structure acpi_device_cls, add cls into the acpi_device_id, and modify the __acpi_match_device to also match for cls. (per Mika suggestion.) * Add loadable module support, which requires changes in ACPI modalias. (per Mika suggestion.) * Rebased and tested with acpi-5.1-v9 Changes from V2 (https://lkml.org/lkml/2015/1/5/662) * Update with review comment from Rafael in patch 1/2 * Rebased and tested with acpi-5.1-v8 Changes from V1 (https://lkml.org/lkml/2014/12/19/345) * Rebased to 3.19.0-rc2 * Change from acpi_cls in device_driver to acpi_match_cls (Hanjun comment) * Change the matching logic in acpi_driver_match_device() due to the new special PRP0001 _HID. * Simplify the return type of acpi_match_device_cls() to boolean. Changes from RFC (https://lkml.org/lkml/2014/12/17/446) * Remove #ifdef and make non-ACPI version of the acpi_match_device_cls as inline. (per Arnd) * Simplify logic to retrieve and evaluate _CLS handle.
