* [PowerPC] [MIPS] Implement 32-bit kernel emulation of atomic64 operationsBrandon Bergren2020-01-021-0/+1
| | | | | | | | | | | | | | | | | | | This is a lock-based emulation of 64-bit atomics for kernel use, split off from an earlier patch by jhibbits. This is needed to unblock future improvements that reduce the need for locking on 64-bit platforms by using atomic updates. The implementation allows for future integration with userland atomic64, but as that implies going through sysarch for every use, the current status quo of userland doing its own locking may be for the best.

* Add support for BERI statcounters.Ruslan Bukin2019-09-181-1/+3
| | | | | | | | | | | | | | | | | | | | BERI stands for Bluespec Extensible RISC Implementation, based on MIPS. BERI has not implemented standard MIPS perfomance monitoring counters, instead it provides statistical counters. BERI statcounters have a several limitations: - They can't be written - They don't support start/stop operation - None of hardware interrupt is provided on a counter overflow. So make it separate to hwpmc_mips module and support process/system counting mode only. Sponsored by: DARPA, AFRL Notes: svn path=/head/; revision=352487
* Move scterm_teken.c from 6 MD files lists to the MI files list so that itBruce Evans2019-02-211-2/+0

It is needed whenever sc is configured, and is more MI than most of the files already in the MI list. This only changes the combined list for arm64 and mips. These arches already cannot build sc or even NOTES. Notes: svn path=/head/; revision=344443
* amd64: implement memcmp in assemblyMateusz Guzik2018-09-271-0/+1
| | | | | | | | | | | | | | | | Both the in-kernel C variant and libc asm variant have very poor performance. The former compiles to a single byte comparison loop, which breaks down even for small sizes. The latter uses rep cmpsq/b which turn out to have very poor throughput and are slower than a hand-coded 32-byte comparison loop. Depending on size this is about 3-4 times faster than the current routines.

* Make ZSTD a real option via ZSTDIO.Sean Bruno2018-07-051-1/+1
| | | | | | | | | | | | | | | | | | It looks like the intent was to allow ZSTD support to be compiled into the kernel with options ZSTDIO. But it doesn't look like that was ever implemented or I'm missing how to do it. I did a cursory audit of kernel config files and made a decision to enable ZSTDIO in riscv GENERIC and mips MALTA configurations. All other kernel configurations already had this option in their kernel configs but they didn't do anything useful as the feature was declared as "standard" prior to this.

* Make memmove an alias for memcpyWarner Losh2018-05-241-1/+0
| | | | | | | | | | | memcpy was an alias for bcopy with arg swap. This code handles overlapping copies, so making memmove an alias is safe.

* Finally, fix Zstd kernel build on MIPS and RISC-VConrad Meyer2018-01-101-0/+3
| | | | | | | | | | | | | | | | | | Add an implementation of the intrinsics invoked by __builtin_ctz{,ll} and __builtin_clz{,ll}, and include this compilation unit on platforms that lack assembly intrinsics for those builtins (MIPS and RISC-V). Future cleanup work might involve bringing these into a mini libcompiler-rt for the standalone kernel environment. Or cleaning up the approach upstream takes for builtins in standalone environments (or just FreeBSD). For now, at least this builds, and doesn't require modifying the vendor code.

* Merge projects/ipsec into head/.Andrey V. Elsukov2017-02-061-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Small summary ------------- o Almost all IPsec releated code was moved into sys/netipsec. o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel option IPSEC_SUPPORT added. It enables support for loading and unloading of ipsec.ko and tcpmd5.ko kernel modules. o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type support was removed. Added TCP/UDP checksum handling for inbound packets that were decapsulated by transport mode SAs. setkey(8) modified to show run-time NAT-T configuration of SA. o New network pseudo interface if_ipsec(4) added. For now it is build as part of ipsec.ko module (or with IPSEC kernel). It implements IPsec virtual tunnels to create route-based VPNs. o The network stack now invokes IPsec functions using special methods. The only one header file <netipsec/ipsec_support.h> should be included to declare all the needed things to work with IPsec. o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed. Now these protocols are handled directly via IPsec methods. o TCP_SIGNATURE support was reworked to be more close to RFC. o PF_KEY SADB was reworked: - now all security associations stored in the single SPI namespace, and all SAs MUST have unique SPI. - several hash tables added to speed up lookups in SADB. - SADB now uses rmlock to protect access, and concurrent threads can do SA lookups in the same time. - many PF_KEY message handlers were reworked to reflect changes in SADB. - SADB_UPDATE message was extended to support new PF_KEY headers: SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They can be used by IKE daemon to change SA addresses. o ipsecrequest and secpolicy structures were cardinally changed to avoid locking protection for ipsecrequest. Now we support only limited number (4) of bundled SAs, but they are supported for both INET and INET6. o INPCB security policy cache was introduced. Each PCB now caches used security policies to avoid SP lookup for each packet. o For inbound security policies added the mode, when the kernel does check for full history of applied IPsec transforms. o References counting rules for security policies and security associations were changed. The proper SA locking added into xform code. o xform code was also changed. Now it is possible to unregister xforms. tdb_xxx structures were changed and renamed to reflect changes in SADB/SPDB, and changed rules for locking and refcounting.

| | | | | | | | | | | | | | | | | | | | Import portions of the PowerPC OF PCI implementation into new file "ofwpci.c", common for other platforms. The files ofw_pci.c and ofw_pci.h from sys/powerpc/ofw no longer exist. All required declarations are moved to sys/dev/ofw/ofwpci.h.

* Switch mips busdma to using the common busdma_buffalloc code. This amountsIan Lepore2015-10-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | to copying in some code from the armv4 busdma, and adapting a few variable and flag names to match the surrounding mips code. Instead of keeping a local cache of prealloced busdma_map structs on a mutex-protected list, set up an uma zone to cache them. Instead of all memory allocations using M_DEVBUF, use new categories M_BUSDMA for allocations of metadata (tags, maps, segment tracking lists), and M_BOUNCE for bounce pages. When buffers are allocated out of the busdma_bufalloc zones the alignment and size of the buffers is known, and the code can skip doing any "partial cacheline flush" logic to preserve data that may be adjacent to the DMA buffer but contain non-DMA data.

* Add proper __sync_*() intrinsics for MIPS.Ed Schouten2013-06-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | To make <stdatomic.h> work on MIPS (and ARM) using GCC, we need to provide implementations of the __sync_*() functions. I already added these functions for 4 and 8 byte types to libcompiler-rt some time ago, based on top of <machine/atomic.h>. Unfortunately, <machine/atomic.h> only provides a subset of the features needed to implement <stdatomic.h>. This means that in some cases we had to do compare-and-exchange calls in loops, where a simple ll/sc would suffice. Also implement these functions for 1 and 2 byte types. MIPS only provides ll/sc instructions for 4 and 8 byte types, but this is of course no limitation. We can simply load 4 bytes and use some bitmask tricks to modify only the bytes affected.

* Add basic support for FDT to i386 & amd64. This change includes:Marcel Moolenaar2013-05-211-1/+1

New modinfo for loader provided FDT blob. 3. Common x86_init_fdt() called from hammer_time() on amd64 and init386() on i386. 4. Split-off FDT specific low-level console functions from FDT bus methods for the uart(4) driver. The low-level console logic has been moved to uart_cpu_fdt.c and is used for arm, mips & powerpc only. The FDT bus methods are shared across all architectures. 5. Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the fdt_pic_table[] arrays. Both are empty right now. FDT addresses are I/O ports on x86. Since the core FDT code does not handle different address spaces, adding support for both I/O ports and memory addresses requires some thought and discussion. It may be better to use a compile-time option that controls this. Obtained from: Juniper Networks, Inc. Notes: svn path=/head/; revision=250840
