* Make MAXPHYS tunable. Bump MAXPHYS to 1M.Konstantin Belousov2020-11-283-17/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work. Changes to cam/, dev/ahci, dev/ata, dev/mpr, dev/mpt, dev/mvs, dev/siis, where either submitted by, or based on changes by mav.

* Limit AHCI to only one MSI if more is not needed.Alexander Motin2020-06-051-1/+5
| | | | | | | | | | | | | | | | My AMD Ryzen system has 4 AHCI controllers, each supporting 16 MSI vectors. Since two of the controllers have only one SATA port, limit to single MSI saves system 30 interrupt vectors for free. It may be possible to also limit number of MSI vectors to 4 and 8 for the other two controllers, but according to the AHCI specification after that controllers may revert to only one vector, that would be a bigger loss to risk.

* Create a AHCI attachment for nvme.Warner Losh2019-08-213-5/+82
| | | | | | | | | | | | | | | | | | | | | | | | | Intel has created RST and many laptops from vendors like Lenovo and Asus. It's a mechanism for creating multiple boot devices under windows. It effectively hides the nvme drive inside of the ahci controller. The details are supposed to be a trade secret. However, there's a reverse engineered Linux driver, and this implements similar operations to allow nvme drives to attach. The ahci driver attaches nvme children that proxy the remapped resources to the child. nvme_ahci is just like nvme_pci, except it doesn't do the PCI specific things. That's moved into ahci where appropriate. When the nvme drive is remapped, MSI-x interrupts aren't forwarded (the linux driver doesn't know how to use this either). INTx interrupts are used instead. This is suboptimal, but usually sufficient for the laptops these parts are in. This is based loosely on https://www.spinics.net/lists/linux-ide/msg53364.html submitted, but not accepted by, Linux. It was written by Dan Williams. These changes were written from scratch by Olivier Houchard. Submitted by: cognet@ (Olivier Houchard) Notes: svn path=/head/; revision=351356
* Improve AHCI Enclosure Management and SES interoperation.Alexander Motin2019-06-233-36/+145
| | | | | | | | | | | | | | | | | | | | | | | | Since SES specs do not define mechanism to map enclosure slots to SATA disks, AHCI EM code I written many years ago appeared quite useless, that always bugged me. I was thinking whether it was a good idea, but if LSI HBAs do that, why I shouldn't? This change introduces simple non-standard mechanism for the mapping into both AHCI EM and SES code, that makes AHCI EM on capable controllers (most of Intel's) a first-class SES citizen, allowing it to report disk physical path to GEOM, show devices inserted into each enclosure slot in `sesutil map` and `getencstat`, control locate and fault LEDs for specific devices with `sesutil locate adaX on` and `sesutil fault adaX on`, etc. I've successfully tested this on Supermicro X10DRH-i motherboard connected with sideband cable of its S-SATA Mini-SAS connector to SAS815TQ backplane. It can indicate with LEDs Locate, Fault and Rebuild/Remap SES statuses for each disk identical to real SES of Supermicro SAS2 backplanes. MFC after: 2 weeks Notes: svn path=/head/; revision=349321

According to the datasheet, the old code checks if port 2 (P2E, 0x4) was the only enabled port (except port 0, which was ignored by mask 0xfe), and issue a write to the PCS register to disable all but port 0, right before ahci_ctlr_reset. Some other operating systems would issue a port enable to all ports, but since the current code only does the special initialization for ICH8M, it entirely and rely on BIOS to do the right thing (the alternative would be https://reviews.freebsd.org/D18300?id=50922 , should we see reports that we really need to do it).

* Implement ability to turn on/off PHYs for AHCI devices.Warner Losh2018-11-032-3/+49
| | | | | | | | | | | | | | | | | | As part of Chuck's work on fixing kernel crashes caused by disk I/O errors, it is useful to be able to trigger various kinds of errors. This patch allows causing an AHCI-attached disk to disappear, by having the driver keep the PHY disabled when the driver would otherwise enable the PHY. It also allows making the disk reappear by having the driver go back to setting the PHY enable/disable state as it normal would and simulating the hardware event that causes a bus rescan.
