e2359fad458a396df0673bc5d876f44ce700439d - Merge branch 'defxx-updates'

Wed, 10 Mar 2021 22:08:15 +0100

Merge branch 'defxx-updates'Maciej W. Rozycki says:====================FDDI: defxx: CSR access fixes and improvementsAs a lab upgrade I have recently replaced a dated 32-bit x86 server witha new POWER9 system. One of the purposes of the system has been providingnetwork based resources to clients over my FDDI network. As such the newserver has also received a new DEFPA FDDI network adapter. As it turned out the interface did not work with the driver as shipped bythe most recent stable Debian release (Linux version 5.9.15) for ppc64el.Symptoms were inconclusive, and the DEFPA adapter turned out to have amanufacturing defect as well, however eventually I have figured out thePCIe host bridge used with the system, Power Systems Host Bridge 4 (PHB4),does not (anymore) implement PCI I/O transactions, while the binary defxxdriver as shipped by Debian comes configured for port I/O, and then a bugin resource handling causes the driver to try and use an unassigned portI/O range for adapter's PDQ main ASIC's CSR access. Fortunately the PFI PCI interface ASIC used with the DEFPA adapter hasbeen designed such as to provide for both PCI I/O and PCI memory accessesto be used for PDQ CSR access, via a pair of BARs to be alternativelyused. Originally the defxx driver only supported port I/O access, but in thecourse of interfacing it to the TURBOchannel bus I had to implement MMIOaccess too, and while at it I have added a kernel configuration option toglobally switch between port I/O and MMIO at compilation time, howeverconservatively defaulting to port I/O for EISA bus support where the useof MMIO currently requires the adapter to have been suitably configuredvia ECU (EISA Configuration Utility), supplied externally. With the kernel configuration option set to MMIO the DEFPA interfaceworks correctly with my POWER9 system. Therefore I have prepared thissmall patch series consisting of a pair of conservative bug fixes, to bebackported to stable branches, and then a pair of improvements for therobustness of the driver. So changes 1/4 and 2/4 apply both to net and net-next, and then changes3/4 and 4/4 apply on top of them to net-next only. In particular thereare diff context dependencies going like this: 1/4 -> 3/4 -> 4/4. Let meknow if this submission needs to be sorted differently. See individual change descriptions for further details as to the actualchanges made. NB the ESIC interface chip used for slave address decoding with the DEFEAEISA adapter has decoding implemented for address bits 31:10 and thereforesupports full 32-bit range for the allocation of the CSR decoding window.For DOS compatibility reasons ECU however only allows allocations between0x000c0000 and 0x000effff. Given that for other compatibility reasons EISA is subtractively decodedon mixed PCI/EISA systems we could allocate an MMIO region from arbitraryunoccupied memory space and program the ESIC suitably without regard forthat compatibility limitation. In fact I have a proof-of-concept changeand it seems to work reliably. However with these patches applied the driver continues supporting portI/O as fallback and the EISA product ID register is located in the EISAslot-specific port I/O address space, so any EISA system however modern(sounds like a joke, eh?) also has to support port I/O access somehow. So while I think such a dynamic MMIO allocation would be an example ofgood engineering, but it would require changes to our EISA core andtherefore it may have had sense 25 years ago when EISA was stillmainstream, but not nowadays when EISA systems are I suppose more of acuriosity rather than the usual equipment. This patch series has been thoroughly verified with Linux 5.11.0 asreleased and then a Raptor Talos II POWER9 system and a Malta 5Kc MIPS64system for PCI DEFPA adapter support, an Advanced Integrated Research486EI x86 system for EISA DEFEA adapter support, and a Digital EquipmentDECstation 5000 model 260 MIPS III system for TURBOchannel DEFTA adaptersupport, covering both port I/O and MMIO operation where applicable.====================Signed-off-by: David S.

795e272e54746e97fde54454873d384d5012cc9d - FDDI: defxx: Implement dynamic CSR I/O address space selection

Wed, 10 Mar 2021 13:03:19 +0100

FDDI: defxx: Implement dynamic CSR I/O address space selectionRecent versions of the PCI Express specification have deprecated supportfor I/O transactions and actually some PCIe host bridges, such as PowerSystems Host Bridge 4 (PHB4), do not implement them. Conversely a DEFEAadapter can have its MMIO decoding disabled with ECU (EISA ConfigurationUtility) and therefore not available for us with the resource allocationinfrastructure we implement.However either I/O address space will always be available for use withthe DEFEA (EISA) and DEFPA (PCI) adapters and both have double addressdecoding implemented in hardware for Control and Status Register access.The two kinds of adapters can be present both at once in a single mixedPCI/EISA system. For the DEFTA (TURBOchannel) variant there is no issueas there has been no port I/O address space defined for that bus.To make people's life easier and the driver more robust remove theDEFXX_MMIO configuration option so as to rather than making the choicefor the I/O address space to use at build time for all the adaptersinstalled in the system let the driver choose the most suitable addressspace dynamically on a case-by-case basis at run time. Make MMIO thedefault and resort to port I/O should the default fail for some reason.This way multiple adapters installed in one system can use different I/Oaddress spaces each, in particular in the presence of DEFEA adapters ina pure-EISA or a mixed EISA/PCI system (it is expected that DEFPA boardswill use MMIO in normal circumstances).The choice of the I/O address space to use continues being reported bythe driver on startup, e.g.:eisa 00:05: EISA: slot 5: DEC3002 detecteddefxx: v1.12 2021/03/10 Lawrence V.

Stefani and otherstc2: DEFTA at MMIO addr = 0x1f100000, IRQ = 21, Hardware addr = 08-00-2b-b0-8b-1etc2: registered as fddi0so there is no need to add further information.The change is supposed to cause a negligible performance hit as I/Oaccessors will now have code executed conditionally at run time.Signed-off-by: Maciej W.

193ced4a79599352d63cb8c9e2f0c6043106eb6a - FDDI: defxx: Make MMIO the configuration default except for EISA

Wed, 10 Mar 2021 13:03:14 +0100

FDDI: defxx: Make MMIO the configuration default except for EISARecent versions of the PCI Express specification have deprecated supportfor I/O transactions and actually some PCIe host bridges, such as PowerSystems Host Bridge 4 (PHB4), do not implement them.The default kernel configuration choice for the defxx driver is the useof I/O ports rather than MMIO for PCI and EISA systems. It may havemade sense as a conservative backwards compatible choice back when MMIOoperation support was added to the driver as a part of TURBOchannel bussupport. However nowadays this configuration choice makes the driverunusable with systems that do not implement I/O transactions for PCIe.Make DEFXX_MMIO the configuration default then, except where configuredfor EISA. This exception is because an EISA adapter can have its MMIOdecoding disabled with ECU (EISA Configuration Utility) and thereforenot available with the resource allocation infrastructure we implement,while port I/O is always readily available as it uses slot-specificaddressing, directly mapped to the slot an option card has been placedin and handled with our EISA bus support core. Conversely a kernel thatsupports modern systems which may not have I/O transactions implementedfor PCIe will usually not be expected to handle legacy EISA systems.The change of the default will make it easier for people, including butnot limited to distribution packagers, to make a working choice for thedriver.Update the option description accordingly and while at it replace thepotentially ambiguous PIO acronym with IOP for "port I/O" vs "I/O ports"according to our nomenclature used elsewhere.Signed-off-by: Maciej W.
