* MIPS: Retire kvm paravirtJiaxun Yang2020-07-241-0/+1
| | | | | | | | | | | | | | paravirt machine was introduced for Cavium's partial virtualization technology, however, it's host side support and QEMU support never landed in upstream. As Cavium was acquired by Marvel and they have no intention to maintain their MIPS product line, also paravirt is unlikely to be utilized by community users, it's time to retire it if nobody steps in to maintain it.

* asm-generic: make more kernel-space headers mandatoryMasahiro Yamada2020-04-021-13/+0

So, mandatory-y works like a fallback default (by just wrapping asm-generic one) when arch does not have a specific header implementation. See the following commits: def3f7cefe4e81c296090e1722a76551142c227c a1b39bae16a62ce4aae02d958224f19316d98b24 It is tedious to convert headers one by one, so I processed by a shell script.

* asm-generic: Make msi.h a mandatory include/asm headerMichal Simek2019-11-261-1/+0
| | | | | | | | | | | | | | | | | | msi.h is generic for all architectures except x86, which has its own version. Enabling MSI by adding msi.h to every architecture's Kbuild is just an additional step which doesn't need to be done. Make msi.h mandatory in the asm-generic/Kbuild so we don't have to do it for each architecture.

* MIPS: remove meaningless generic-(CONFIG_GENERIC_CSUM) += checksum.hMasahiro Yamada2019-01-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This line is weird in multiple ways. (CONFIG_GENERIC_CSUM) might be a typo of $(CONFIG_GENERIC_CSUM). Even if you add '$' to it, $(CONFIG_GENERIC_CSUM) is never evaluated to 'y' because scripts/Makefile.asm-generic does not include include/config/auto.conf. So, the asm-generic wrapper of checksum.h is never generated. Even if you manage to generate it, it is never included by anyone because MIPS has the checkin header with the same file name: arch/mips/include/asm/checksum.h As you see in the top Makefile, the checkin headers are included before generated ones.

This feature will allow consumers to lock in a certain rate on the output of a clk so that things like audio playback don't hear pops when the clk frequency changes due to shared parent clks changing rates. Currently the clk API doesn't guarantee the rate of a clk stays at the rate you request after clk_set_rate() is called, so this new API will allow drivers to express that requirement. Beyond this, the core got some debugfs pretty printing patches and a couple minor non-critical fixes. Looking outside of the core framework diff we have some new driver additions and the removal of a legacy TI clk driver. Both of these hit high in the dirstat. Also, the removal of the asm-generic/clkdev.h file causes small one-liners in all the architecture Kbuild files. Overall, the driver diff seems to be the normal stuff that comes all the time to fix little problems here and there and to support new hardware.

* | MIPS: Add custom serial.h with BASE_BAUD override for generic kernelMatt Redfearn2017-11-281-1/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Add a custom serial.h header for MIPS, allowing platforms to override the asm-generic version if required. The generic platform uses this header to set BASE_BAUD to 0. The generic platform supports multiple boards, which may have different UART clocks. Also one of the boards supported is the Boston FPGA board, where the UART clock depends on the loaded FPGA bitfile. As such there is no way that the generic kernel can set a compile time default BASE_BAUD. Commit 31cb9a8575ca ("earlycon: initialise baud field of earlycon device structure") changed the behavior of of_setup_earlycon such that any baud rate set in the device tree is now set in the earlycon structure. The UART driver will then calculate a divisor based on BASE_BAUD and set it. With MIPS generic kernels this resulted in garbage output due to the incorrect uart clock rate being used to calculate a divisor. This commit, combined with "serial: 8250_early: Only set divisor if valid clk & baud" prevents the earlycon code setting a bad divisor and restores earlycon output.

Chris sent this during the merge window, but I waffled back and forth on the pull request, which is why it's going in only now. The new "strscpy()" function is definitely easier to use and more secure than either strncpy() or strlcpy(), both of which are horrible nasty interfaces that have serious and irredeemable problems. strncpy() has a useless return value, and doesn't NUL-terminate an overlong result. To make matters worse, it pads a short result with zeroes, which is a performance disaster if you have big buffers. strlcpy(), by contrast, is a mis-designed "fix" for strlcpy(), lacking the insane NUL padding, but having a differently broken return value which returns the original length of the source string. Which means that it will read characters past the count from the source buffer, and you have to trust the source to be properly terminated. It also makes error handling fragile, since the test for overflow is unnecessarily subtle. strscpy() avoids both these problems, guaranteeing the NUL termination (but not excessive padding) if the destination size wasn't zero, and making the overflow condition very obvious by returning -E2BIG. It also doesn't read past the size of the source, and can thus be used for untrusted source data too. So why did I waffle about this for so long? Every time we introduce a new-and-improved interface, people start doing these interminable series of trivial conversion patches. And every time that happens, somebody does some silly mistake, and the conversion patch to the improved interface actually makes things worse. Because the patch is mindnumbing and trivial, nobody has the attention span to look at it carefully, and it's usually done over large swatches of source code which means that not every conversion gets tested. So I'm pulling the strscpy() support because it *is* a better interface. But I will refuse to pull mindless conversion patches. Use this in places where it makes sense, but don't do trivial patches to fix things that aren't actually known to be broken. * 'strscpy' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: tile: use global strscpy() rather than private copy string: provide strscpy() Make asm/word-at-a-time.h available on all architectures

* | MIPS: Add definitions for extended contextPaul Burton2015-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The context introduced by MSA needs to be saved around signals. However, we can't increase the size of struct sigcontext because that will change the offset of the signal mask in struct sigframe or struct ucontext. This patch instead places the new context immediately after the struct sigframe for traditional signals, or similarly after struct ucontext for RT signals. The layout of struct sigframe & struct ucontext is identical from their sigcontext fields onwards, so the offset from the sigcontext to the extended context will always be the same regardless of the type of signal. Userland will be able to search through the extended context by using the magic values to detect which types of context are present. Any unrecognised context can be skipped over using the size field of struct extcontext. Once the magic value END_EXTCONTEXT_MAGIC is seen it is known that there are no further extended context structures to examine. This approach is somewhat similar to that taken by ARM to save VFP & other context at the end of struct ucontext. Userland can determine whether extended context is present by checking for the USED_EXTCONTEXT bit in the sc_used_math field of struct sigcontext. Whilst this could potentially change the historic semantics of sc_used_math if further extended context which does not imply FP context were to be introduced in the future, I have been unable to find any userland code making use of sc_used_math at all. Using one of the fields described as unused in struct sigcontext was considered, but the kernel does not already write to those fields so there would be no guarantee of the field being clear on older kernels. Other alternatives would be to have userland check the kernel version, or to have a HWCAP bit indicating presence of extended context. However there is a desire to have the context & information required to decode it be self contained such that, for example, debuggers could decode the saved context easily.

* tracing,x86: Add a TSC trace_clockDavid Sharp2012-11-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to promote interoperability between userspace tracers and ftrace, add a trace_clock that reports raw TSC values which will then be recorded in the ring buffer. Userspace tracers that also record TSCs are then on exactly the same time base as the kernel and events can be unambiguously interlaced. Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large timestamp values. v2: Move arch-specific bits out of generic code. v3: Rename "x86-tsc", cleanups v7: Generic arch bits in Kbuild.

* UAPI: Place comments in empty arch Kbuilds to make them non-emptyDavid Howells2012-10-171-0/+1
| | | | | | | | | | | | | | | | | | | | | Place comments in: arch/mips/include/asm/Kbuild arch/tile/include/arch/Kbuild to make them non-empty so that the patch program doesn't remove them when it reduces them to nothing. Possibly they should be just deleted, but it's possible that they'll acquire generic-y or genhdr-y lines in future, so I'm keeping them around for the moment. Note that MIPS will compile happily if the file is deleted instead. I haven't tested TILE, but I suspect it will be the same there.
