2019-01-22parisc: iomap: introduce io{read|write}64Logan Gunthorpe1-0/+64
Add support for io{read|write}64() functions in parisc architecture. These are pretty straightforward copies of similar functions which make use of readq and writeq. Also, indicate that the lo_hi and hi_lo variants of these functions are not provided by this architecture.

2018-08-13parisc: Fix and improve kernel stack unwindingHelge Deller1-21/+0
This patchset fixes and improves stack unwinding a lot: 1. Show backward stack traces with up to 30 callsites 2. Add callinfo to ENTRY_CFI() such that every assembler function will get an entry in the unwind table 3. Use constants instead of numbers in call_on_stack() 4. Do not depend on CONFIG_KALLSYMS to generate backtraces. 5. Speed up backtrace generation Make sure you have this patch to GNU as installed: https://sourceware.org/ml/binutils/2018-07/msg00474.html Without this patch, unwind info in the kernel is often wrong for various functions.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman5-0/+5
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.

2017-04-15parisc: fix bugs in pa_memcpyMikulas Patocka1-13/+14
The patch 554bfeceb8a22d448cd986fc9efce25e833278a1 ("parisc: Fix access fault handling in pa_memcpy()") reimplements the pa_memcpy function. Unfortunatelly, it makes the kernel unbootable. The crash happens in the function ide_complete_cmd where memcpy is called with the same source and destination address. This patch fixes a few bugs in pa_memcpy: * When jumping to .Lcopy_loop_16 for the first time, don't skip the instruction "ldi 31,t0" (this bug made the kernel unbootable) * Use the COND macro when comparing length, so that the comparison is 64-bit (a theoretical issue, in case the length is greater than 0xffffffff) * Don't use the COND macro after the "extru" instruction (the PA-RISC specification says that the upper 32-bits of extru result are undefined, although they are set to zero in practice) * Fix exception addresses in .Lcopy16_fault and .Lcopy8_fault * Rename .Lcopy_loop_4 to .Lcopy_loop_8 (so that it is consistent with .Lcopy8_fault) Cc: <stable@vger.kernel.org> # v4.9+ Fixes: 554bfeceb8a2 ("parisc: Fix access fault handling in pa_memcpy()") Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Helge Deller <deller@gmx.de>

2017-03-29parisc: Clean up fixup routines for get_user()/put_user()Helge Deller2-99/+1
Al Viro noticed that userspace accesses via get_user()/put_user() can be simplified a lot with regard to usage of the exception handling. This patch implements a fixup routine for get_user() and put_user() in such that the exception handler will automatically load -EFAULT into the register %r8 (the error value) in case on a fault on userspace. Additionally the fixup routine will zero the target register on fault in case of a get_user() call. The target register is extracted out of the faulting assembly instruction. This patch brings a few benefits over the old implementation: 1. Exception handling gets much cleaner, easier and smaller in size. 2. Helper functions like fixup_get_user_skip_1 (all of fixup.S) can be dropped. 3. No need to hardcode %r9 as target register for get_user() any longer. This helps the compiler register allocator and thus creates less assembler statements. 4. No dependency on the exception_data contents any longer. 5. Nested faults will be handled cleanly.

2017-03-29parisc: Fix access fault handling in pa_memcpy()Helge Deller2-458/+321
pa_memcpy() is the major memcpy implementation in the parisc kernel which is used to do any kind of userspace/kernel memory copies. Al Viro noticed various bugs in the implementation of pa_mempcy(), most notably that in case of faults it may report back to have copied more bytes than it actually did. Fixing those bugs is quite hard in the C-implementation, because the compiler is messing around with the registers and we are not guaranteed that specific variables are always in the same processor registers. This makes proper fault handling complicated. This patch implements pa_memcpy() in assembler. That way we have correct fault handling and adding a 64-bit copy routine was quite easy. Runtime tested with 32- and 64bit kernels.

2016-05-22parisc: Add native high-resolution sched_clock() implementationHelge Deller1-4/+2
Add a native implementation for the sched_clock() function which utilizes the processor-internal cycle counter (Control Register 16) as high-resolution time source. With this patch we now get much more fine-grained resolutions in various in-kernel time measurements (e.g. when viewing the function tracing logs), and probably a more accurate scheduling on SMP systems. There are a few specific implementation details in this patch: 1. On a 32bit kernel we emulate the higher 32bits of the required 64-bit resolution of sched_clock() by increasing a per-cpu counter at every wrap-around of the 32bit cycle counter. 2. In a SMP system, the cycle counters of the various CPUs are not syncronized (similiar to the TSC in a x86_64 system). To cope with this we define HAVE_UNSTABLE_SCHED_CLOCK and let the upper layers do the adjustment work. 3. Since we need HAVE_UNSTABLE_SCHED_CLOCK, we need to provide a cmpxchg64() function even on a 32-bit kernel. 4. A 64-bit SMP kernel which is started on a UP system will mark the sched_clock() implementation as "stable", which means that we don't expect any jumps in the returned counter. This is true because we then run only on one CPU. Signed-off-by: Helge Deller <deller@gmx.de>
2016-04-08parisc: Unbreak handling exceptions from kernel modulesHelge Deller1-0/+6
Handling exceptions from modules never worked on parisc. It was just masked by the fact that exceptions from modules don't happen during normal use. When a module triggers an exception in get_user() we need to load the main kernel dp value before accessing the exception_data structure, and afterwards restore the original dp value of the module on exit.

Since this seems to be a generic problem with gcc-4.7.x (and below), it's better to simplify the fault handlers in pa_memcpy to avoid this problem. Here is a simple reproducer for the problem: int main(int argc, char **argv) { int fd, nbytes; struct iovec wr_iovec[] = { { "TEST STRING ",32}, { (char*)0x40005000,32} }; // random memory. fd = open(DATA_FILE, O_RDWR | O_CREAT, 0666); nbytes = writev(fd, wr_iovec, 2); printf("return value = %d, errno %d (%s)\n", nbytes, errno, strerror(errno)); return 0; } In addition, John David Anglin wrote: There is no gcc PR as pa_memcpy is not legitimate C code. There is an implicit assumption that certain variables will contain correct values when an exception occurs and the code randomly jumps to one of the exception blocks. There is no guarantee of this. If a PR was filed, it would likely be marked as invalid.

2008-04-29iomap: fix 64 bits resources on 32 bitsBenjamin Herrenschmidt1-2/+2
Almost all implementations of pci_iomap() in the kernel, including the generic lib/iomap.c one, copies the content of a struct resource into unsigned long's which will break on 32 bits platforms with 64 bits resources. This fixes all definitions of pci_iomap() to use resource_size_t. I also "fixed" the 64bits arch for consistency.

2007-12-06Revert "[PARISC] import necessary bits of libgcc.a"Kyle McMartin29-4627/+1
This reverts commit efb80e7e097d0888e59fbbe4ded2ac5a256f556d, it turned out to cause sporadic problems with the timer interrupt on 32-bit kernels. Needs more investigation. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
2007-10-18[PARISC] import necessary bits of libgcc.aKyle McMartin29-1/+4627
Currently we're hacking libs-y to include libgcc.a, but this has unforeseen consequences since the userspace libgcc is linked with fpregs enabled. We need the kernel to stop using fpregs in an uncontrolled manner to implement lazy fpu state saves. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
