4cc167a3 - Restore PPS_SYNC in NOTES

Mon, 11 Oct 2021 22:02:35 +0000

Restore PPS_SYNC in NOTESThis partially reverts e81e77c5a055, leaving the option both inGENERICs on amd64/arm64/arm, and in global NOTES file. Apparentlythis better matches existing practice, where we do not try to hardto make LINT and GENERIC complimentary.Requested and reviewed by: jhbSponsored by: The FreeBSD FoundationMFC after: 1 week List of files: /freebsd-14.2/sys/powerpc/conf/NOTES

4efb1ca7 - [PowerPC64LE] Work around qemu TCG bug in mtmsrd emulation.

Wed, 23 Sep 2020 00:09:29 +0000

[PowerPC64LE] Work around qemu TCG bug in mtmsrd emulation.The TCG implementation of mtmsrd in qemu blindly copies the entire registerto the MSR, instead of the specific bit positions listed in the ISA.This means that qemu will prematurely switch endian out from under therunning code instead of waiting for the rfid, causing an immediate trapas it attempts to interpret the next instruction in the wrong endianness.To work around this, ensure PSL_LE is still set before doing the mtmsrd.In the future, we may wish to just turn off translation and unconditionallyuse rfid to switch to the ofmsr instead of quasi-switching to the ofmsr.Add a new platform option so this can be disabled. (And so that we canconditonalize additional QEMU-specific hacks in the platform code.)Sponsored by: Tag1 Consulting, Inc. List of files: /freebsd-14.2/sys/powerpc/conf/NOTES

99e1c5ab - Move sc out of the global file

Mon, 12 Aug 2019 22:58:44 +0000

Move sc out of the global filex86 needs sc, as does sparc64. powerpc doesn't use it by default, but some oldpowermac notebooks do not work with vt yet for reasons unknonw. Even so, I'veremoved it from powerpc LINT. It's not in daily use there, and the intent is to100% switch to vt now that it works for that platform to limit support burden.All the other architectures omit some or all of the screen savers from theirlint config. Move them to the x86 NOTES files and remove the exclusions. Thisreduces slightly the number of savers sparc64 compiles, but since they are inGENERIC, the overage is adequate and if someone reaelly wants to sort them outin sparc64 they can sweat the details and the testing.Reviewed by: jhb (earlier version), manu (earlier version), jhibbitsDifferential Revision: https://reviews.freebsd.org/D21233 List of files: /freebsd-14.2/sys/powerpc/conf/NOTES

5033c43b - Add a driver for the Chelsio T6 crypto accelerator engine.

Wed, 17 May 2017 22:13:07 +0000

Add a driver for the Chelsio T6 crypto accelerator engine.The ccr(4) driver supports use of the crypto accelerator engine onChelsio T6 NICs in "lookaside" mode via the opencrypto framework.Currently, the driver supports AES-CBC, AES-CTR, AES-GCM, and AES-XTScipher algorithms as well as the SHA1-HMAC, SHA2-256-HMAC, SHA2-384-HMAC,and SHA2-512-HMAC authentication algorithms. The driver also supportschaining one of AES-CBC, AES-CTR, or AES-XTS with an authenticationalgorithm for encrypt-then-authenticate operations.Note that this driver is still under active development and testing andmay not yet be ready for production use. It does pass the tests intests/sys/opencrypto with the exception that the AES-GCM implementationin the driver does not yet support requests with a zero byte payload.To use this driver currently, the "uwire" configuration must be usedalong with explicitly enabling support for lookaside crypto capabilitiesin the cxgbe(4) driver. These can be done by setting the followingtunables before loading the cxgbe(4) driver: hw.cxgbe.config_file=uwire hw.cxgbe.cryptocaps_allowed=-1MFC after: 1 monthRelnotes: yesSponsored by: Chelsio CommunicationsDifferential Revision: https://reviews.freebsd.org/D10763 List of files: /freebsd-14.2/sys/powerpc/conf/NOTES

6af45170 - Chelsio T4/T5 VF driver.

Wed, 07 Sep 2016 18:13:57 +0000

Chelsio T4/T5 VF driver.The cxgbev/cxlv driver supports Virtual Function devices for ChelsioT4 and T4 adapters. The VF devices share most of their code with theexisting PF4 driver (cxgbe/cxl) and as such the VF device drivercurrently depends on the PF4 driver.Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vfPCI device driver that attaches to the VF device. It then createschild cxgbev/cxlv devices representing ports assigned to the VF.By default, the PF driver assigns a single port to each VF.t4vf_hw.c contains VF-specific routines from the shared code used tofetch VF-specific parameters from the firmware.t4_vf.c contains the VF-specific PCI device driver and includes itsown attach routine.VF devices are required to use a different firmware request whentransmitting packets (which in turn requires a different CPL messageto encapsulate messages). This alternate firmware request does notpermit chaining multiple packets in a single message, so each packetresults in a firmware request. In addition, the different CPL messagerequires more detailed information when enabling hardware checksums,so parse_pkt() on VF devices must examine L2 and L3 headers for allpackets (not just TSO packets) for VF devices. Finally, L2 checksumson non-UDP/non-TCP packets do not work reliably (the firmware trashesthe IPv4 fragment field), so IPv4 checksums for such packets arecalculated in software.Most of the other changes in the non-VF-specific code are to exposevarious variables and functions private to the PF driver so that theycan be used by the VF driver.Note that a limited subset of cxgbetool functions are supported on VFdevices including register dumps, scheduler classes, and clearing ofstatistics. In addition, TOE is not supported on VF devices, only forthe PF interfaces.Reviewed by: npMFC after: 2 monthsSponsored by: Chelsio CommunicationsDifferential Revision: https://reviews.freebsd.org/D7599 List of files: /freebsd-14.2/sys/powerpc/conf/NOTES
