[PATCH v4 0/3] [RFC] Add support for PCI in AArch64

by Liviu Dudau

Hi, This patch adds support for PCI to AArch64. It is based on my v4 patch that adds support for creating generic host bridge structure from device tree. With that in place, I was able to boot a platform that has PCIe host bridge support and use a PCIe network card. Changes from v3: - Added Acks accumulated so far ;) - Still carrying Catalin's patch for moving the PCI_IO_BASE until it lands in linux-next or mainline, in order to ease applying the series Changes from v2: - Implement an arch specific version of pci_register_io_range() and pci_address_to_pio(). - Return 1 from pci_proc_domain(). Changes from v1: - Added Catalin's patch for moving the PCI_IO_BASE location and extend its size to 16MB - Integrated Arnd's version of pci_ioremap_io that uses a bitmap for keeping track of assigned IO space and returns an io_offset. At the moment the code is added in arch/arm64 but it can be moved in drivers/pci. - Added a fix for the generic ioport_map() function when !CONFIG_GENERIC_IOMAP as suggested by Arnd. The API used is different from the one used by ARM architecture. There is no pci_common_init_dev() function and no hw_pci structure, as that is no longer needed. Once the last signature is added to the legal agreement, I will post the host bridge driver code that I am using. Meanwhile, here is an example of what the probe function looks like, posted as an example: static int myhostbridge_probe(struct platform_device *pdev) { int err; struct device_node *dev; struct pci_host_bridge *bridge; struct myhostbridge_port *pp; resource_size_t lastbus; dev = pdev->dev.of_node; if (!of_device_is_available(dev)) { pr_warn("%s: disabled\n", dev->full_name); return -ENODEV; } pp = kzalloc(sizeof(struct myhostbridge_port), GFP_KERNEL); if (!pp) return -ENOMEM; bridge = of_create_pci_host_bridge(&pdev->dev, &myhostbridge_ops, pp); if (IS_ERR(bridge)) { err = PTR_ERR(bridge); goto bridge_create_fail; } err = myhostbridge_setup(bridge->bus); if (err) goto bridge_setup_fail; /* We always enable PCI domains and we keep domain 0 backward * compatible in /proc for video cards */ pci_add_flags(PCI_ENABLE_PROC_DOMAINS); pci_add_flags(PCI_REASSIGN_ALL_BUS | PCI_REASSIGN_ALL_RSRC); lastbus = pci_scan_child_bus(bridge->bus); pci_bus_update_busn_res_end(bridge->bus, lastbus); pci_assign_unassigned_bus_resources(bridge->bus); pci_bus_add_devices(bridge->bus); return 0; bridge_setup_fail: put_device(&bridge->dev); device_unregister(&bridge->dev); bridge_create_fail: kfree(pp); return err; } Best regards, Liviu Catalin Marinas (1): arm64: Extend the PCI I/O space to 16MB Liviu Dudau (2): Fix ioport_map() for !CONFIG_GENERIC_IOMAP cases. arm64: Add architecture support for PCI Documentation/arm64/memory.txt | 16 ++-- arch/arm64/Kconfig | 19 ++++- arch/arm64/include/asm/Kbuild | 1 + arch/arm64/include/asm/io.h | 5 +- arch/arm64/include/asm/pci.h | 47 +++++++++++ arch/arm64/kernel/Makefile | 1 + arch/arm64/kernel/pci.c | 178 +++++++++++++++++++++++++++++++++++++++++ include/asm-generic/io.h | 2 +- 8 files changed, 259 insertions(+), 10 deletions(-) create mode 100644 arch/arm64/include/asm/pci.h create mode 100644 arch/arm64/kernel/pci.c -- 1.9.0

[RFC v2 PATCH 0/1] ARM64: KGDB: Add FPSIMD debug support

by vijay.kilari＠gmail.com

From: Vijaya Kumar K <Vijaya.Kumar(a)caviumnetworks.com> Based on ARM64 KGDB support patches, KGDB support for FPSIMD is added. Only debugging of FPSIMD kernel context is supported. This patch requires Ard's patches where in kernel support and below patch for holding thread's fpsimd state. http://permalink.gmane.org/gmane.linux.ports.arm.kernel/277228 So CONFIG_KERNEL_MODE_NEON should be enabled. with this, FPSIMD registers can be viewed or set from gdb tool. Unlike CPU registers, the FPSIMD registers are not saved on exception entry. With the known restriction that FPSIMD should not be touched in interrupt/exception context, in this patch the FPSIMD registers are directly read/written on gdb tool request Here, the FPSIMD registers are read and restored for every FPSIMD register read and write by GDB tool. So this has impact on gdb tool response which is neglible. Other architectures like mips are also implemented similarly v2 changes: - Added API to know thread fpsimd state by checking TIF_FOREIGN_FPSTATE flag. This is based on below patch http://permalink.gmane.org/gmane.linux.ports.arm.kernel/277228 - Allow FPSIMD registers access only when FPSIMD is under use by current thread v1 changes: - Initial patch Tested on ARM64 simulator Vijaya Kumar K (1): ARM64: KGDB: Add FP/SIMD debug support arch/arm64/include/asm/fpsimd.h | 1 + arch/arm64/kernel/fpsimd.c | 5 ++ arch/arm64/kernel/kgdb.c | 105 +++++++++++++++++++++++++-------------- 3 files changed, 73 insertions(+), 38 deletions(-) -- 1.7.9.5

[PATCH V4 1/5] idle/cpuidle: Split cpuidle_idle_call main function into smaller functions

by Daniel Lezcano

In order to allow better integration between the cpuidle framework and the scheduler, reducing the distance between these two sub-components will facilitate this integration by moving part of the cpuidle code in the idle task file and, because idle.c is in the sched directory, we have access to the scheduler's private structures. This patch splits the cpuidle_idle_call main entry function into 3 calls to a newly added API: 1. select the idle state 2. enter the idle state 3. reflect the idle state The cpuidle_idle_call calls these three functions to implement the main idle entry function.

[PATCH V6 0/7] cpufreq: suspend early/resume late: dpm_{suspend|resume}()

by Viresh Kumar

This patchset creates/calls cpufreq suspend/resume callbacks from dpm_{suspend|resume}() for handling suspend/resume of cpufreq governors and core. There are multiple problems that are fixed by this patch: - Nishanth Menon (TI) found an interesting problem on his platform, OMAP. His board wasn't working well with suspend/resume as calls for removing non-boot CPUs was turning out into a call to drivers ->target() which then tries to play with regulators. But regulators and their I2C bus were already suspended and this resulted in a failure. Many platforms have such problems, samsung, tegra, etc.. They solved it with driver specific PM notifiers where they used to disable their driver's ->target() routine. - Lan Tianyu (Intel) & Jinhyuk Choi (Broadcom) found an issue where tunables configuration for clusters/sockets with non-boot CPUs was getting lost after suspend/resume, as we were notifying governors with CPUFREQ_GOV_POLICY_EXIT on removal of the last cpu for that policy and so deallocating memory for tunables. This is fixed by this patch as we don't allow any operation on governors after device suspend and before device resume now. This is already tested by few people and so incorporating their Tested-by as well. I have tested this again on latest stuff on my thinkpad for several suspend/resume cycles. V6->V7: - Fixed crash reported by S.Warren on systems without a cpufreq driver. - Moved some function doc-comments to patch 1 from a later patch. For-v3.15 Viresh Kumar (7): cpufreq: suspend governors on system suspend/hibernate cpufreq: suspend governors from dpm_{suspend|resume}() cpufreq: call driver's suspend/resume for each policy cpufreq: Implement cpufreq_generic_suspend() cpufreq: exynos: Use cpufreq_generic_suspend() cpufreq: s5pv210: Use cpufreq_generic_suspend() cpufreq: Tegra: Use cpufreq_generic_suspend() drivers/base/power/main.c | 5 ++ drivers/cpufreq/cpufreq.c | 137 +++++++++++++++++++++++--------------- drivers/cpufreq/exynos-cpufreq.c | 96 ++------------------------ drivers/cpufreq/s5pv210-cpufreq.c | 49 +------------- drivers/cpufreq/tegra-cpufreq.c | 46 ++----------- include/linux/cpufreq.h | 11 +++ 6 files changed, 113 insertions(+), 231 deletions(-) -- 1.7.12.rc2.18.g61b472e
