powerpc/sysdev: drop simple gpio There is a config item CONFIG_SIMPLE_GPIO which provides simple memory mapped GPIOs specific to powerpc. However, the only platform which selects this option is mpc5200, and this platform doesn't use it. There are three boards calling simple_gpiochip_init(), but as they don't select CONFIG_SIMPLE_GPIO, this is just a nop. Simple_gpio is just redundant with the generic MMIO GPIO driver which can be found in driver/gpio/ and selected via CONFIG_GPIO_GENERIC_PLATFORM, so drop simple_gpio driver.

powerpc: Add -Werror at arch/powerpc level Back when I added -Werror in commit ba55bd74360e ("powerpc: Add configurable -Werror for arch/powerpc") I did it by adding it to most of the arch Makefiles. At the time we excluded math-emu, because apparently it didn't build cleanly. But that seems to have been fixed somewhere in the interim. So move the -Werror addition to the top-level of the arch, this saves us from repeating it in every Makefile and means we won't forget to add it to any new sub-dirs.

powerpc/cell: Remove axonram driver The QS21/22 IBM Cell blades had a southbridge chip called Axon. This could have DDR DIMMs attached to it, though they were not directly usable as RAM, instead they could be used as some sort of buffer, if applications were written specifically to use the block device provided by the driver. Although the driver supposedly had direct access support, it was apparently never tested (see commit 91117a20245b ("axonram: Fix bug in direct_access")). These machines have not been available for over 5 years, and were never widely in use. It seems highly unlikely anyone is using this driver. In general we're happy to leave old drivers in the tree, but because DAX is involved this driver is caught up in the ongoing work in that area, but none of the DAX folks are able to test it. So remove the driver, if any one *is* using it, we'll be happy to put it back. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

powerpc/xive: Native exploitation of the XIVE interrupt controller The XIVE interrupt controller is the new interrupt controller found in POWER9. It supports advanced virtualization capabilities among other things. Currently we use a set of firmware calls that simulate the old "XICS" interrupt controller but this is fairly inefficient. This adds the framework for using XIVE along with a native backend which OPAL for configuration. Later, a backend allowing the use in a KVM or PowerVM guest will also be provided. This disables some fast path for interrupts in KVM when XIVE is enabled as these rely on the firmware emulation code which is no longer available when the XIVE is used natively by Linux. A latter patch will make KVM also directly exploit the XIVE, thus recovering the lost performance (and more).

The two independent groups of global timer on fsl chip, group A and group B, are identical in their functionality, except that they appear at different locations within the PIC register map. The hardware timer can be cascaded to create timers larger than the default 31-bit global timers. Timer cascade fields allow configuration of up to two 63-bit timers. But These two groups of timers cannot be cascaded together. It can be used as a wakeup source for low power modes.

powerpc/mpic: FSL MPIC error interrupt support. All SOC device error interrupts are muxed and delivered to the core as a single MPIC error interrupt. Currently all the device drivers requiring access to device errors have to register for the MPIC error interrupt as a shared interrupt. With this patch we add interrupt demuxing capability in the mpic driver, allowing device drivers to register for their individual error interrupts. This is achieved by handling error interrupts in a cascaded fashion. MPIC error interrupt is handled by the "error_int_handler", which subsequently demuxes it using the EISR and delivers it to the respective drivers. The error interrupt capability is dependent on the MPIC EIMR register, which was introduced in FSL MPIC version 4.1 (P4080 rev2). So, error interrupt demuxing capability is dependent on the MPIC version and can be used for versions >= 4.1.

fsl-rio: Split rio driver into two parts, RapidIO endpoint and message unit The Freescale PowerPC RapidIO controller consists of a RapidIO endpoint and a RapidIO message unit(RMU). Or use RapidIO message manager(RMan) to replace the RMU in DPAA architecture. Therefore, we should split the code into two function modules according to the hardware architecture. Add new struct for RMU module, and new initialization function to set up RMU module. This policy is very conducive to adding new module like RMan, or adding multi-ports or message units support.

powerpc: introduce the ePAPR embedded hypervisor vmpic driver The Freescale ePAPR reference hypervisor provides interrupt controller services via a hypercall interface, instead of emulating the MPIC controller. This is called the VMPIC. The ePAPR "virtual interrupt controller" provides interrupt controller services for external interrupts. External interrupts received by a partition can come from two sources: - Hardware interrupts - hardware interrupts come from external interrupt lines or on-chip I/O devices. - Virtual interrupts - virtual interrupts are generated by the hypervisor as part of some hypervisor service or hypervisor-created virtual device. Both types of interrupts are processed using the same programming model and same set of hypercalls.

The driver is moved to a more generic location to allow new platforms to use it, and is broken up into separate ICP and ICS "backends". For now we have the native and "hypervisor" ICP backends and one common RTAS ICS backend. The driver supports one ICP backend instanciation, and many ICS ones, in order to accomodate future platforms with multiple possibly different interrupt "sources" mechanisms.

The option is a negative, ie. don't enable -Werror, so that it will be turned on for allyes and allmodconfig builds. The default is n, in the hope that developers will build with -Werror, that will probably lead to some build breaks, I am prepared to be flamed.

powerpc: Split-out common MSI bitmap logic into msi_bitmap.c There are now two almost identical implementations of an MSI bitmap allocator, one in mpic_msi.c and the other in fsl_msi.c. Merge them together and put the result in msi_bitmap.c. Some of the MPIC bits will remain to provide a nicer interface for the MPIC users. In the process we fix two buglets. The first is that the allocation routines, now msi_bitmap_alloc_hwirqs(), returned an unsigned result, even though they use -1 to indicate allocation failure. Although all the callers were checking correctly, it is much better for the routine to just return an int. At least until someone wants > ~2 billion MSIs. The second buglet is that the device tree reservation logic only allowed power-of-two reservations. AFAICT that didn't effect any existing code but it's nicer if we can reserve arbitrary irqs from MSI use. We also add some selftests, which exposed the two buglets and now test for them, as well as some basic sanity tests. The tests are only built when CONFIG_DEBUG_KERNEL=y.

There are 256 MSI interrupts in this host, Every 32 MSI interrupts cascaded to one IPIC/MPIC interrupt. The chip was treated as edge sensitive and some necessary functions were setup for this chip. Before using the MSI interrupt, PCI/PCIE device need to ask for a MSI interrupt in the 256 MSI interrupts. A 256bit bitmap show which MSI interrupt was used, reserve bit in the bitmap can be used to force the device use some designate MSI interrupt in the 256 MSI interrupts. Sometimes this is useful for testing the all the MSI interrupts. The msi-available-ranges property in the dts file was used for this purpose.

[POWERPC] Enable RTC for Ebony and Walnut (v2) This patch extends the Ebony and Walnut platform code to instantiate the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip found on both those boards. The patch uses a helper function to scan the device tree and instantiate the appropriate platform_device based on it, so it should be easy to extend for other boards which have mmio mapped RTC chips. Along with this, the device tree binding for the ds1743 chips is tweaked, based on the existing DS1385 OF binding found at: http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt Although that document covers the NVRAM portion of the chip, whereas here we're interested in the RTC portion, so it's not entirely clear if that's a good model. This implements only RTC class driver support - that is /dev/rtc0, not /dev/rtc, and the low-level get/set time callbacks remain unimplemented. That means in order to get at the clock you will either need a modified version of hwclock which will look at /dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

[POWERPC] pasemi: Implement MSI support Implement MSI support for PA Semi PWRficient platforms. MSI is done through a special range of sources on the openpic controller, and they're unfortunately breaking the usual concepts of how sources are programmed: * The source is calculated as 512 + the value written into the MSI register * The vector for this source is added to the source and reported through IACK This means that for simplicity, it makes much more sense to just set the vector to 0 for the source, since that's really the vector we expect to see from IACK. Also, the affinity/priority registers will affect 16 sources at a time. To avoid most (simple) users from being limited by this, allocate 16 sources per device but use only one. This means that there's a total of 32 sources. If we get usage scenarions that need more sources, the allocator should probably be revised to take an alignment argument and size, not just do natural alignment. Finally, since I'm already touching the MPIC names on pasemi, rename the base one from the somewhat odd " PAS-OPIC " to "PASEMI-OPIC".

These functions are enabled if an mv64x60 port is to be used as the console as determined from the device tree. Signed-off-by: Dale Farnsworth <dale@farnsworth.org> Acked-by: Mark A.

[CELL] driver for DDR2 memory on AXON The Axon bridge chip used on new Cell/B.E. based blade servers comes with a DDR2 memory controller that can be used to attach cheap memory modules, as opposed to the high-speed XDR memory that is used by the CPU itself. Since the memory controller does not participate in the cache coherency protocol, we can not use the memory direcly for Linux applications, but by providing a block device it can be used for swap space, temporary file storage and through the use of the direct_access block device operation for mapping into user addresses, when it is mounted with an appropriate file system.

[POWERPC] Don't link timer.o for powerpc systems using generic rtc With both generic rtc and powerpc timer suspend / resume code now in the (powerpc.git) tree, powerpc platforms using the generic timer and enabling power management will have timer.o linked in the kernel, which they don't need. Moreover, it will likely WARN_ON(!ppc_md.get_rtc_time), save zero-time and return no error on suspend... As a possible solution we can choose not to build timer.o when RTC_CLASS is enabled. However, I can imagine systems with 2 rtc's, one served by the ppc-rtc, another one generic built as a module, in which case using the ppc-rtc for suspend / resume will be impossible.

[POWERPC] Abolish powerpc_flash_init() powerpc_flash_init() implements a broken way of probing for flash devices supported by the physmap_of driver. It finds all nodes in the device tree with device_type=="rom" and instantiates of_platform devices for them. This is fundamentally incompatible with the normal and correct way of probing for of_platform_bus_probe().

If we find a U3/U4 then we enable this backend, ie. take over the ppc_md MSI hooks. We might need more elaborate logic in future to decide which backend is enabled. We need our own irq_chip so that we can do MSI masking/unmasking on the device itself. We also need to mask explicitly on shutdown to make sure we don't get bitten by lazy-disable semantics.

powerpc: Merge enough to start building in arch/powerpc. This creates the directory structure under arch/powerpc and a bunch of Kconfig files. It does a first-cut merge of arch/powerpc/mm, arch/powerpc/lib and arch/powerpc/platforms/powermac. This is enough to build a 32-bit powermac kernel with ARCH=powerpc. For now we are getting some unmerged files from arch/ppc/kernel and arch/ppc/syslib, or arch/ppc64/kernel. This makes some minor changes to files in those directories and files outside arch/powerpc. The boot directory is still not merged. That's going to be interesting. Signed-off-by: Paul Mackerras <paulus@samba.org>
