2015-02-11tools build: Add new build supportJiri Olsa
Adding new build framework into 'tools/build' to be used by tools. There's no change for actual building at this point, it comes in the next patches. The idea and more details are explained in the 'tools/build/Documentation/Build.txt' file. I adopted everything from the kernel build system, with some changes to allow for multiple binaries build definitions. While the kernel's build output is single image (forget modules) we need to be able to build several binaries/libraries. The basic idea is that sser provides 'Build' files with objects definitions like: perf-y += a.o perf-y += b.o libperf-y += c.o libperf-y += d.o and the build framework outputs files: perf-in.o # a.o, b.o compiled in libperf-in.o # c.o, d.o compiled in Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Tested-by: Will Deacon <will.deacon@arm.com> Cc: Alexis Berlemont <alexis.berlemont@gmail.com> Cc: Borislav Petkov <bp@alien8.de> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-fbj22h4av0otlxupwcmrxgpa@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2015-02-11perf tools: Define _GNU_SOURCE on pthread_attr_setaffinity_np feature checkJosh Boyer
The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE must be defined before pthread.h is included in order to get the proper function declaration. Define this in the Makefile. Without this defined, the feature check fails on a Fedora system with gcc5 and then the perf build later fails with conflicting prototypes for the function.

2015-02-11perf tools: Make perf aware of tracefsSteven Rostedt (Red Hat)

2015-02-11lguest: support backdoor window.Rusty Russell
The VIRTIO_PCI_CAP_PCI_CFG in the PCI virtio 1.0 spec allows access to the BAR registers without mapping them. This is a compulsory feature, and we implement it here. There are some subtleties involving access widths which we should note: 4.1.4.7.1 Device Requirements: PCI configuration access capability ... Upon detecting driver write access to pci_cfg_data, the device MUST execute a write access at offset cap.offset at BAR selected by cap.bar using the first cap.length bytes from pci_cfg_data. Upon detecting driver read access to pci_cfg_data, the device MUST execute a read access of length cap.length at offset cap.offset at BAR selected by cap.bar and store the first cap.length bytes in pci_cfg_data. So, for a write, we copy into the pci_cfg_data window, then write from there out to the BAR. This works correctly if cap.length != width of write. Similarly, for a read, we read into window from the BAR then read the value from there. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2015-02-11lguest: Convert net device to virtio 1.0 PCI.Rusty Russell
The only real change here (other than using the PCI bus) is that we didn't negotiate VIRTIO_NET_F_MRG_RXBUF before, so the format of the packet header changed with virtio 1.0; we need TUNSETVNETHDRSZ on the tun fd to tell it about the extra two bytes. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2015-02-11lguest: Convert block device to virtio 1.0 PCI.Rusty Russell
We remove SCSI support (which was removed for 1.0) and VIRTIO_BLK_F_FLUSH feature flag (removed too, since it's compulsory for 1.0). The rest is mainly mechanical. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2015-02-11lguest: fix failure to find linux/virtio_types.hRusty Russell
We want to use the local kernel headers, but -I../../include/uapi leads us into a world of hurt. Instead we create a dummy include/ dir with symlinks. If we just use #include "../../include/uapi/linux/virtio_blk.h" we get: ../../include/uapi/linux/virtio_blk.h:31:32: fatal error: linux/virtio_types.h: No such file or directory #include <linux/virtio_types.h> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2015-02-11lguest: implement virtio-PCI MMIO accesses.Rusty Russell
For each device, We need to include the vendor capabilities to demark where virtio common, notification and ISR regions are (we put them all in BAR0). We need to handle the switching of the virtqueues using the accessors. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2015-02-11lguest: add PCI config space emulation to example launcher.Rusty Russell
This handles ioport 0xCF8 and 0xCFC accesses, which are used to read/write PCI device config space. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2015-02-11lguest: decode mmio accesses for PCI in example launcher.Rusty Russell
We don't do anything with them yet (emulate_mmio_write and emulate_mmio_read are stubs), but we decode the instructions and search for the device they're hitting. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2015-02-11lguest: add MMIO region allocator in example launcher.Rusty Russell
This is where we point our PCI BARs, so that we can intercept MMIO accesses. We tell the kernel about it so any faults in this area are directed to us. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2015-02-11lguest: add iomem region, where guest page faults get sent to userspace.Rusty Russell
This lets us implement PCI. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2015-02-11lguest: suppress PS/2 keyboard polling.Rusty Russell
While hacking on getting I/O out to the lguest launcher, I noticed that returning 0xFF for the PS/2 keyboard status made it spin for a while thinking there was a key pending. Fix this by returning 1 instead of 0xFF. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2015-02-11lguest: send trap 13 through to userspace.Rusty Russell
We copy 7 bytes at eip for userspace's instruction decode; we have to carefully handle the case where eip is at the end of a page. We can't leave this to userspace since kernel has all the page table decode logic. The decode logic moves to userspace, basically unchanged. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "We have a few new features this time, including a new SFI-based cpufreq driver, a new devfreq driver for Tegra Activity Monitor, a new devfreq class for providing its governors with raw utilization data and a new ACPI driver for AMD SoCs. Still, the majority of changes here are reworks of existing code to make it more straightforward or to prepare it for implementing new features on top of it. The primary example is the rework of ACPI resources handling from Jiang Liu, Thomas Gleixner and Lv Zheng with support for IOAPIC hotplug implemented on top of it, but there is quite a number of changes of this kind in the cpufreq core, ACPICA, ACPI EC driver, ACPI processor driver and the generic power domains core code too. The most active developer is Viresh Kumar with his cpufreq changes. Specifics: - Rework of the core ACPI resources parsing code to fix issues in it and make using resource offsets more convenient and consolidation of some resource-handing code in a couple of places that have grown analagous data structures and code to cover the the same gap in the core (Jiang Liu, Thomas Gleixner, Lv Zheng). - ACPI-based IOAPIC hotplug support on top of the resources handling rework (Jiang Liu, Yinghai Lu). - ACPICA update to upstream release 20150204 including an interrupt handling rework that allows drivers to install raw handlers for ACPI GPEs which then become entirely responsible for the given GPE and the ACPICA core code won't touch it (Lv Zheng, David E Box, Octavian Purdila). - ACPI EC driver rework to fix several concurrency issues and other problems related to events handling on top of the ACPICA's new support for raw GPE handlers (Lv Zheng). - New ACPI driver for AMD SoCs analogous to the LPSS (Low-Power Subsystem) driver for Intel chips (Ken Xue). - Two minor fixes of the ACPI LPSS driver (Heikki Krogerus, Jarkko Nikula). - Two new blacklist entries for machines (Samsung 730U3E/740U3E and 510R) where the native backlight interface doesn't work correctly while the ACPI one does (Hans de Goede). - Rework of the ACPI processor driver's handling of idle states to make the code more straightforward and less bloated overall (Rafael J Wysocki). - Assorted minor fixes related to ACPI and SFI (Andreas Ruprecht, Andy Shevchenko, Hanjun Guo, Jan Beulich, Rafael J Wysocki, Yaowei Bai). - PCI core power management modification to avoid resuming (some) runtime-suspended devices during system suspend if they are in the right states already (Rafael J Wysocki). - New SFI-based cpufreq driver for Intel platforms using SFI (Srinidhi Kasagar). - cpufreq core fixes, cleanups and simplifications (Viresh Kumar, Doug Anderson, Wolfram Sang). - SkyLake CPU support and other updates for the intel_pstate driver (Kristen Carlson Accardi, Srinivas Pandruvada). - cpufreq-dt driver cleanup (Markus Elfring). - Init fix for the ARM big.LITTLE cpuidle driver (Sudeep Holla). - Generic power domains core code fixes and cleanups (Ulf Hansson). - Operating Performance Points (OPP) core code cleanups and kernel documentation update (Nishanth Menon). - New dabugfs interface to make the list of PM QoS constraints available to user space (Nishanth Menon). - New devfreq driver for Tegra Activity Monitor (Tomeu Vizoso). - New devfreq class (devfreq_event) to provide raw utilization data to devfreq governors (Chanwoo Choi). - Assorted minor fixes and cleanups related to power management (Andreas Ruprecht, Krzysztof Kozlowski, Rickard Strandqvist, Pavel Machek, Todd E Brandt, Wonhong Kwon). - turbostat updates (Len Brown) and cpupower Makefile improvement (Sriram Raghunathan)" * tag 'pm+acpi-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (151 commits) tools/power turbostat: relax dependency on APERF_MSR tools/power turbostat: relax dependency on invariant TSC Merge branch 'pci/host-generic' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci into acpi-resources tools/power turbostat: decode MSR_*_PERF_LIMIT_REASONS tools/power turbostat: relax dependency on root permission ACPI / video: Add disable_native_backlight quirk for Samsung 510R ACPI / PM: Remove unneeded nested #ifdef USB / PM: Remove unneeded #ifdef and associated dead code intel_pstate: provide option to only use intel_pstate with HWP ACPI / EC: Add GPE reference counting debugging messages ACPI / EC: Add query flushing support ACPI / EC: Refine command storm prevention support ACPI / EC: Add command flushing support.
