* fwsectors and fwheads used to be somehwat arbitrary. However, they areimp2014-10-161-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | used to align partitions in gpart. We also try to align partitions by stripe size when creating new media. Align these two concepts by making fwsectors the same as the stripe size. Select a sensible number of heads so we wind up with about 20 cylinders. This number was selected to keep the rounding effects to a few percent while keeping the number of cylinder groups low. Sadly, it is not possible to make these numbers match the numbers used by SD card readers. There apperas to be much variation between brands so there's no one universal number. These numbers are also not aligned to the stripe size, so some performance problems may still be present when SD cards are created this way. Also, these numbers will differ from the far less common SD to ATA adapters, which present a different, but more uniform, set of numbers that also happened to match the old defaults. Nothing should change for current users. Any suboptimal performance caused by misalignment will still be there. gpart will honor the partitions that aren't on proper boudnaries, but editing the partition tables may result in different alignments being used than before when editing things natively. Ideally, there'd be some way to override these values in the disk subsystem by the user for the USB adapter use case where all "native" notions of geometry disappear. This does not implement that.

* Make the standard sdhci(4) driver work for the TI OMAP family SoCs.ian2013-08-201-0/+1
| | | | | | | | | | | | | | The MMCHS hardware is pretty much a standard SDHCI v2.0 controller with a couple quirks, which are now supported by sdhci(4) as of r254507. This should work for all TI SoCs that use the MMCHS hardware, but it has only been tested on AM335x right now, so this enables it on those platforms but leaves the existing ti_mmchs driver in place for other OMAP variants until they can be tested. This initial incarnation lacks DMA support (coming soon). Even without it this improves performance pretty noticibly over the ti_mmchs driver, primarily because it now does multiblock IO.

* Handle command retries for commands originating at the mmc layer, andian2013-08-161-32/+41
| | | | | | | | | | | | | | | | | | | | ensure that all such commands have a non-zero retry count except for those that are expected to fail (for example, because they are used to probe for feature support). While it is possible to pass a retry count down to the hardware driver in the command request structure, no hardware driver currently implements any retry logic. The hardware doesn't know much about the context of a single request, so it makes more sense to handle retries at a layer that does. This adds retry loops to the mmc_wait_for_cmd() and mmc_wait_for_app_cmd() functions. These functions are the gateway from other code within mmc.c to the hardware. App commands are a sequence of two commands and a retry has to rerun both of them in order, so it needs its own retry loop. Retry looping is specifically NOT implemented in mmc_wait_for_request() because it is the gateway for children on the bus, and they have to implement their own retry logic depending on what makes sense for them.

| | | | | | | | | | | | | | | | | | | | | | | | | | - When switching to 4-bit operation, send a SET_CLR_CARD_DETECT command to disconnect the card-detect pull-up resistor from the DAT3 line before sending the SET_BUS_WIDTH command. - Add the missing "reserved" zero entry to the mantissa table used to decode various CSD fields. This was causing SD cards to report that they could run at 30 MHz instead of the maximum 25 MHz mandated in the spec. o Enhancements: - At the MMC layer, format various info from the CID into a string that uniquely identifies the card instance (manufacturer number, serial number, product name and revision, etc). Export it as an instance variable. - At the MMCSD layer, display the formatted card ID string, and also report the clock speed of the hardware (not the card's max speed), and the number of bits and number of blocks per transfer. It comes out like this now: mmcsd0: 968MB <SD SD01G 8.0 SN 276886905 MFG 08/2008 by 3 SD> at mmc0 22.5MHz/4bit/128-block o Use DEVMETHOD_END. o Use NULL instead of 0 for pointers.

* Make the newbus subsystem Giant free by adding the new newbus sxlock.attilio2009-08-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races. Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped. For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens. Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing. Bump __FreeBSD_version in order to reflect the newbus lock introduction. Reviewed by: ed, hps, jhb, imp, mav, scottl No answer by: ariff, thompsa, yongari Tested by: pho, G.
