Add the needed accessor in the {read,write}_ivar functions. Reviewed by: imp (previous version) r349728 by imp: Implement missing MMCBR ivars All MMCBR bridges have to implement all the MMCBR variables. This implements them for everybody that currently doesn't. A common routine for this should be written. r349731 by imp: Fix cut-and-pasto that slipped through my testing. r350440 by br: Add support for the SD/MMC controller found in Terasic DE10-Pro (an Intel Stratix 10 GX/SX FPGA Development Kit). Set the bus speed manually due to lack of clock management support. Sponsored by: DARPA, AFRL r350443 by br: Fix MMCCAM kernel build. Sponsored by: DARPA, AFRL r351185 by mmel: Enhance support of extres in dwmmc driver. Handle all clocks, regulators and resets defined by dwmmc bindings. r353493 by br: Fix the driver attachment in cases when the external resource devices (resets, regulators, clocks) are not available. Rely on a system initialization done by a bootloader in that cases. This fixes operation on Terasic DE10-Pro (an Intel Stratix 10 development kit). Sponsored by: DARPA, AFRL r353575 by br: Fix dwmmc(4) driver attachment when ext_resources are not present. Ignore only ENOENT (no DTS properties found) and ENODEV (driver not present) non-zero return values from ext_resources. Reviewed by: manu Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D22043 r355625: dwmmc: Add a detach method This method will disable the regulators, clocks and assert the reset of the module. It will also detach it's children (the mmc device) and release it's resources. While here enable the regulators on attach as we need them to power up the sdcard or emmc. r355627: dwmmc: Handle the card detect interrupt The driver used to always add the mmc device as it's child even it no card was detected. Add a function that will detect if the card is present or not and that will attach/detach the mmc device. The function is either call on attach (as we won't have the interrupt fired) or from two taskqueues. The first taskqueue will directly call the function when the sdcard was present and is now removed and the other one will delay a bit the attach when we didn't had a card and now have one. This is mostly based on comments from the sdhci driver where it describe a situation when the CD pin is detected before the others pins are connected. r355629: dwmmc: Use device_delete_children Instead of first detaching the children(s) and then delete them, use the device_delete_children function that does all of that. Suggested by: ian r356813: dwmmc: Remove max_hz from the softc We never use it so directly set the value to the mmc host structure. 2020-05-12T21:51:56Z Justin Hibbits jhibbits@FreeBSD.org 2020-05-12T21:51:56Z urn:sha1:35c525dbe0648675e58309e05cf73e928c0cf175 Performance improvements for octe(4): - Distribute RX load across multiple cores, if present. This reverts r217212, which is no longer relevant (I think because of the newer SDK). - Use newer APIs for pinning taskqueue entries to specific cores. - Deepen RX buffers. This more than doubles NAT forwarding throughput on an EdgeRouter Lite from, with typical packet mixture, 90 Mbps to over 200 Mbps. The result matches forwarding throughput in Linux without the UBNT hardware offload on the same hardware, and thus likely reflects hardware limits. 2020-05-08T14:10:47Z Mark Johnston markj@FreeBSD.org 2020-05-08T14:10:47Z urn:sha1:679551199cf29370635716d81260d896c9a02528 Fix a race between _pmap_unwire_ptp() and MipsDoTLBMiss(). 2020-05-08T14:10:29Z Mark Johnston markj@FreeBSD.org 2020-05-08T14:10:29Z urn:sha1:ea114faa4b22203e3581ae689d962e0fab58f958 Fix a race in pmap_emulate_modified(). 2020-05-06T17:12:26Z Brooks Davis brooks@FreeBSD.org 2020-05-06T17:12:26Z urn:sha1:e2a9231d67d8e58577d0bcbec91ca8a8d8c79414 Don't directly access userspace memory. Rather then using the racy useracc() followed by direct access to userspace memory, perform a copyin() and use the result if it succeeds.
