From: Al Stone <ahs3(a)redhat.com> This patch set is in the acpi-topic-seattle branch of acpi.git. The basic idea is that these patches are an example of how to implement ACPI for the AMD Seattle platform. Many of them have been borrowed from the Fedora arm64 kernel tree which is at: git://git.fedorahosted.org/git/kernel-arm64.git Additional patches come from Linaro and LKMLA. With the exception of the PCI patches, or others mentioned below, the intent is that the original authors of these patches will submit them upstream. As always, they rely on the ACPI core patches already being in place. Patches 0001-006 are some cleanup and nice-to-have patches that let ACPI, UEFI and the Seattle platform work better together. Patch 0007 is Graeme's SBSA console patch, which ultimately needs to be replaced with a proper pl011 console driver (still being worked on by ARM, I believe). Patch 0008 introduces ACPI support for the Seattle's AHCI code. Patch 0009 fixes a compilation error in the PNP code. Patch 0010 introduces some skeleton PCI functions to be replaced later. Patch 0011 adds support for the secondary CPU parking protocol. Patches 0011 and 0012 add general support for the AMD XGBE 10Gbe network interface. Patches 0014-0025 are from the device properties previously posted on the ACPI mailing list; these may need updates if the final versions put into the Linux tree differ. NB: 0017-0025 are not strictly required for Seattle, but have been included so that the entire patch set posted on LKMLA is included. Patch 0026 adds ACPI support to the AMD XGBE 10Gbe interface. Yes, just one patch. Patch 0027 adds code to make it easy to set up DMA coherency on a device using ACPI. Patch 0028 may or may not be useful for upstream; it corrects a problem with DMA operations when ACPI and PCI are being used but there may be better ways to handle it. Patch 0029 removes at DT dependency in the arch timer that can cause a hang when using ACPI. Patches 0030-0034 do basic PCI setup based on the contents of the MCFG table in ACPI (for PCIe); these are also a first generation and definitely need refinement and refactoring -- in some cases, there is code duplicated from x86 or ia64, for example. Patches 0035-0037 fix compiler warnings that annoyed me. Patch 0038 allows one to skip adding a console= parameter on the command line. These patches were tested on an AMD Seattle platform, using the 71C version of their firmware (future versions will have needed fixes for PCI windows and some other odds and ends). The kernel command line was: BOOT_IMAGE=/Image.acpi.git root=UUID=d5f87d27-cd7d-4ac5-9e16-dfa850ae32ad \ ro console=ttySBSA0,115200 earlycon=sbsauart,0xe1010000 vconsole.keymap=us \ crashkernel=auto vconsole.font=latarcyrheb-sun16 acpi=force \ acpi_force_table_verification uefi_debug The console, SATA, and NIC all work as expected. PCIe works (PCI will need a new DSDT) with a SATA card I had laying around. It is known to work with a couple of other PCIe devices, but that's all I tried. Things to do: -- Get PCI re-done; there are way too many x86-isms in the code, and some serious refactoring and cleanup is needed; the ia64 seems to have taken some good steps in this direction. -- MSI(-X) support: a DT version has been posted, and some ACPI work is under way. -- KVM support: ACPI support patches are available, but were not included here since I have not had time to test them. -- Subject the code to the full FWTS; this is pending available LAVA machines and some patches to FWTS, but the CI loop is set up. -- Plus whatever ACPI spec changes or additions arise....

[RFC PATCH 0/2] Introduce ACPI support for ahci_platform driver

by Suravee Suthikulpanit

From: Suravee Suthikulpanit <Suravee.Suthikulpanit(a)amd.com> This patch series introduce ACPI support for non-PCI AHCI platform driver. Existing ACPI support for AHCI assumes the device controller is a PCI device. Also, since there is no ACPI _HID/_CID for generic AHCI controller, the driver could not use them for matching devices. Therefore, this patch introduces a mechanism for drivers to match devices using ACPI _CLS method. This patch series is rebased from: http://git.linaro.org/leg/acpi/acpi.git acpi-5.1-v6 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 Suravee Suthikulpanit (2): ACPI / scan: Add support for ACPI _CLS device matching ata: ahci_platform: Add ACPI _CLS matching drivers/acpi/scan.c | 73 +++++++++++++++++++++++++++++++++++++++++ drivers/ata/Kconfig | 2 +- drivers/ata/ahci_platform.c | 10 ++++++ include/acpi/acnames.h | 1 + include/linux/acpi.h | 12 ++++++- include/linux/device.h | 1 + include/linux/mod_devicetable.h | 6 ++++ 7 files changed, 103 insertions(+), 2 deletions(-) -- 1.9.3

[PATCH] Mailbox: Complete wait event only if Tx was successful

by Ashwin Chaugule

If a wait_for_completion_timeout() call returns due to a timeout, the mbox code can still call complete() after returning from the wait. This can cause subsequent transmissions on a channel to fail, since the wait_for_completion_timeout() sees the completion variable is !=0, caused by the erroneous complete() call, and immediately returns without waiting for the time as expected by the client. Fix this by calling complete() only if the TX was successful.

[PATCH 0/5] ACPI based NUMA support for ARM64

by Hanjun Guo

With ACPI arm64 core paches and NUMA patch from Ganapatrao, I prepared those ACPI based NUMA support for ARM64. updates since RFC version: - Address some comments from Arnd - I tested those patches on simulation platform and find the mappings of CPU to NUMA node and memory to NUMA node are correct; - fix some compile issues with CONFIG_ACPI_NUMA disabled; - fix logical problem for the mappings of CPU to node ID There is still a warning about not released a early remapped memory, I'm working on it now.

luvOS build and boot on ARM64

by Naresh Bhat

Hi, The luvOS distribution is booting on arm64 FVP base model. The log goes here https://pastebin.linaro.org/view/dc319415 certainly it is required to update the FWTS with arm64 patches. The git repo - http://git.linaro.org/people/naresh.bhat/luvOS/luv-yocto.git The wiki page is Under construction...:) If you want to try it on your machine. You can just copy and paste the below commands on your machine after installing the OE/Yocto dependency packages on your host machine distribution. $ git clone ssh://git@git.linaro.org/people/naresh.bhat/luvOS/luv-yocto.git $ cd luv-yocto $ . ./oe-init-build-env $ vim conf/local.conf and change the following lines in your local.conf file BB_NUMBER_THREADS ?= "16" ... ...... MACHINE ??= "genericarmv8" .... ......... DISTRO ?= "luv" save and quit local.conf file $ vim conf/bblayers.conf Add the following line to BBLAYERS variable <project-path>/luv-yocto/meta-luv e.g. BBLAYERS ?= " \ /home/nareshbhat/Projects/OE/arm64/luv-yocto/meta \ /home/nareshbhat/Projects/OE/arm64/luv-yocto/meta-yocto \ /home/nareshbhat/Projects/OE/arm64/luv-yocto/meta-yocto-bsp \ /home/nareshbhat/Projects/OE/arm64/luv-yocto/meta-luv \ " Save and quit the bblayers.conf file Now, you can start building the project $ bitbake luv-live-image which generates HDD image, ISO image. You can also generate the core-image-efi image which gives a rootfs from command $ bitbake core-image-efi Let me know if you have any issues. -Cheers Naresh
