* MIPS: Remove dev_err() usage after platform_get_irq()Stephen Boyd2019-08-261-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong.

| * MIPS: ralink: Select CONFIG_CPU_MIPSR2_IRQ_VI on MT7620/8Stefan Roese2018-12-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Testing has shown, that when using mainline U-Boot on MT7688 based boards, the system may hang or crash while mounting the root-fs. The main issue here is that mainline U-Boot configures EBase to a value near the end of system memory. And with CONFIG_CPU_MIPSR2_IRQ_VI disabled, trap_init() will not allocate a new area to place the exception handler. The original value will be used and the handler will be copied to this location, which might already be used by some userspace application. The MT7688 supports VI - its config3 register is 0x00002420, so VInt (Bit 5) is set. But without setting CONFIG_CPU_MIPSR2_IRQ_VI this bit will not be evaluated to result in "cpu_has_vi" being set. This patch now selects CONFIG_CPU_MIPSR2_IRQ_VI on MT7620/8 which results trap_init() to allocate some memory for the exception handler. Please note that this issue was not seen with the Mediatek U-Boot version, as it does not touch EBase (stays at default of 0x8000.0000). This is strictly also not correct as the kernel (_text) resides here.

* MIPS: ralink: Fix booting on MT7621NeilBrown2018-03-221-20/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 3af5a67c86a3 ("MIPS: Fix early CM probing") the MT7621 has not been able to boot. This commit caused mips_cm_probe() to be called before mt7621.c::proc_soc_init(). prom_soc_init() has a comment explaining that mips_cm_probe() "wipes out the bootloader config" and means that configuration registers are no longer available. It has some code to re-enable this config. Before this re-enable code is run, the sysc register cannot be read, so when SYSC_REG_CHIP_NAME0 is read, a garbage value is returned and panic() is called. If we move the config-repair code to the top of prom_soc_init(), the registers can be read and boot can proceed. Very occasionally, the first register read after the reconfiguration returns garbage, so add a call to __sync().

* MIPS: ralink: Remove ralink_halt()NeilBrown2018-03-211-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | ralink_halt() does nothing that machine_halt() doesn't already do, so it adds no value. It actually causes incorrect behaviour due to the "unreachable()" at the end. This tells the compiler that the end of the function will never be reached, which isn't true. The compiler responds by not adding a 'return' instruction, so control simply moves on to whatever bytes come afterwards in memory. In my tested, that was the ralink_restart() function. This means that an attempt to 'halt' the machine would actually cause a reboot. So remove ralink_halt() so that a 'halt' really does halt.

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.

* MIPS: CPS: Have asm/mips-cps.h include CM & CPC headersPaul Burton2017-08-301-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | With Coherence Manager (CM) 3.5 information about the topology of the system, which has previously only been available through & accessed from the CM, is now also provided by the Cluster Power Controller (CPC). This includes a new CPC_CONFIG register mirroring GCR_CONFIG, and similarly a new CPC_Cx_CONFIG register mirroring GCR_Cx_CONFIG. In preparation for adjusting functions such as mips_cm_numcores(), which have previously only needed to access the CM, to also access the CPC this patch modifies the way we use the various CPS headers. Rather than having users include asm/mips-cm.h or asm/mips-cpc.h individually we instead have users include asm/mips-cps.h which in turn includes asm/mips-cm.h & asm/mips-cpc.h. This means that users will gain access to both CM & CPC registers by including one header, and most importantly it makes asm/mips-cps.h an ideal location for helper functions which need to access the various components of the CPS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CLOCKSOURCE_OF_DECLARE macro is used widely for the timers to declare the clocksource at early stage. However, this macro is also used to initialize the clockevent if any, or the clockevent only. It was originally suggested to declare another macro to initialize a clockevent, so in order to separate the two entities even they belong to the same IP. This was not accepted because of the impact on the DT where splitting a clocksource/clockevent definition does not make sense as it is a Linux concept not a hardware description. On the other side, the clocksource has not interrupt declared while the clockevent has, so it is easy from the driver to know if the description is for a clockevent or a clocksource, IOW it could be implemented at the driver level. So instead of dealing with a named clocksource macro, let's use a more generic one: TIMER_OF_DECLARE. The patch has not functional changes.

Make the MIPS arch's clockevent drivers initialize these fields properly. This patch alone doesn't introduce any change in functionality as the clockevents core still looks exclusively at the (untouched) ->min_delta_ns and ->max_delta_ns. As soon as this has changed, a followup patch will purge the initialization of ->min_delta_ns and ->max_delta_ns from these drivers.

* MIPS: Audit and remove any unnecessary uses of module.hPaul Gortmaker2017-02-146-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically a lot of these existed because we did not have a distinction between what was modular code and what was providing support to modules via EXPORT_SYMBOL and friends. That changed when we forked out support for the latter into the export.h file. This means we should be able to reduce the usage of module.h in code that is obj-y Makefile or bool Kconfig. In the case of some code where it is modular, we can extend that to also include files that are building basic support functionality but not related to loading or registering the final module; such files also have no need whatsoever for module.h The advantage in removing such instances is that module.h itself sources about 15 other headers; adding significantly to what we feed cpp, and it can obscure what headers we are effectively using. Since module.h might have been the implicit source for init.h (for __init) and for export.h (for EXPORT_SYMBOL) we consider each instance for the presence of either and replace/add as needed. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. Build coverage of all the mips defconfigs revealed the module.h header was masking a couple of implicit include instances, so we add the appropriate headers there.

* ralink: Introduce fw_passed_dtb to arch/mips/ralinkTobias Wolf2017-01-031-2/+10
| | | | | | | | | | | | This patch adds fw_passed_dtb to arch/mips/ralink to support CONFIG_MIPS_RAW_APPENDED_DTB. Furthermore it adds a check that __dtb_start is not the same address as __dtb_end.

* MIPS: ralink: Make timer explicitly non-modularPaul Gortmaker2016-10-041-21/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Makefile entry controlling compilation of this code is "obj-y" meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments. We don't replace module.h with init.h since the file already has that.

Also includes is a minor SSB cleanup as SSB code traditionally is merged through the MIPS tree: ATH25: - MIPS: Add default configuration for ath25 Boot: - For zboot, copy appended dtb to the end of the kernel - store the appended dtb address in a variable BPF: - Fix off by one error in offset allocation Cobalt code: - Fix typos Core code: - debugfs_create_file returns NULL on error, so don't use IS_ERR for testing for errors. - Fix double locking issue in RM7000 S-cache code. This would only affect RM7000 ARC systems on reboot. - Fix page table corruption on THP permission changes. - Use compat_sys_keyctl for 32 bit userspace on 64 bit kernels. David says, there are no compatibility issues raised by this fix. - Move some signal code around. - Rewrite r4k count/compare clockevent device registration such that min_delta_ticks/max_delta_ticks files are guaranteed to be initialized. - Only register r4k count/compare as clockevent device if we can assume the clock to be constant. - Fix MSA asm warnings in control reg accessors - uasm and tlbex fixes and tweaking. - Print segment physical address when EU=1. - Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO. - CP: Allow booting by VP other than VP 0 - Cache handling fixes and optimizations for r4k class caches - Add hotplug support for R6 processors - Cleanup hotplug bits in kconfig - traps: return correct si code for accessing nonmapped addresses - Remove cpu_has_safe_index_cacheops Lantiq: - Register IRQ handler for virtual IRQ number - Fix EIU interrupt loading code - Use the real EXIN count - Fix build error.
