* [SCSI] libsas: Warn if ATA device detected but CONFIG_SCSI_SAS_ATA not setJames Bottomley2008-03-27
| | | | | | | | | We give a very cryptic error if an ATA device is seen on a SAS port but libsas isn't compiled to include libata to handle them. Add an extra warning to explain specifically what the problem is. Acked-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

* ACPI: fix Medion _PRT quirk (use "ISA_", not "ISA")Bjorn Helgaas2008-03-25
| | | | | | | | | | | | | | | | | This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop. The BIOS reports the interrupt routing incorrectly. I recently added a quirk to work around this, and this patch fixes a typo in the quirk. We pad every ACPI pathname component to four characters, so ".ISA." will never match anything. We need ".ISA_." instead. Thank you Johann-Nikolaus Andreae <johann-nikolaus.andreae@nacs.de> for patiently testing this patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an I2C interrupt happens between disabling interface clock and functional clock, the interrupt handler will produce an external abort on non-linefetch error when trying to access driver registers while interface clock is disabled. This patch fixes the problem by saving and disabling i2c-omap interrupt before turning off the clocks. Also disable functional clock before the interface clock as suggested by Paul Walmsley. Patch also renames enable/disable_clocks functions to unidle/idle functions. Note that the driver is currently not taking advantage of the idle interrupts. To use the idle interrupts, driver would have to enable interface clock based on the idle interrupt and dev->idle flag. This patch has been tested in linux-omap tree with various omaps.

A (partial) datasheet for this chip eventually turned up, letting us see how to make it use a VIA-specific register to switch over to the the normal 10us value instead, as suggested by the EHCI specification Solution noted by Lev A. Melnikovsky. It's not clear whether this register exists on other VIA chips; we know that it's ineffective on the vt8235.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lockdep goes off on the iova copy_reserved_iova() because it and a function it calls grabs locks in the from, and the to of the copy operation. The function grab locks of the same lock classes triggering the warning. The first lock grabbed is for the constant reserved areas that is never accessed after early boot. Technically you could do without grabbing the locks for the "from" structure its copying reserved areas from. But dropping the from locks to me looks wrong, even though it would be ok. The affected code only runs in early boot as its setting up the DMAR engines. This patch gives the reserved_ioval_list locks special lockdep classes.

These events aren't masked by the driver, and the unexpected interrupts will cause a sequence of failed reset attempts util libata's EH finally gives up. This has not been a common problem so far, but the pending libata hardreset-by-default changes makes it a critical issue. The solution is to disable hotplug events before a reset, and to reenable them afterwards. (Promise's driver does this too.) This patch adds SATA-specific versions of ->freeze() and ->thaw() that also disable and enable hotplug events. PATA ports continue to use the old versions of ->freeze() and ->thaw(). Accesses to the hotplug register must be serialised via host->lock. We rely on ap->lock == &ap->host->lock and that libata takes this lock before ->freeze() and ->thaw(). Document this requirement. The interrupt handler is adjusted so its hotplug register accesses are inside the region protected by host->lock. Tested on various chips (SATA300TX4, SATA300TX2plus, SATAII150TX4, FastTrack TX4000) with various combinations of SATA and PATA disks, with and without the pending hardreset-by-default changes.

Modify EH such that it assumes no device is attached if both flavors of IDENTIFY are aborted by the device. There really isn't much point in retrying when the device actively aborts the commands.

If we loop more than once in gem_poll(), we'll use more than the real budget in our gem_rx() calls, thus eventually trigger the caller's assertions in net_rx_action(). Subtract "work_done" from "budget" for the second arg to gem_rx() to fix the bug. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | On 10GBaseT boards setting the type to TP will cause the driver to try to configure 1GBaseT. Since there are currently no boards that support setting of the port type, disable this for now. Signed-off-by: Eliezer Tamir <eliezert@broadcom.com> Signed-off-by: David S.

* | | | mmc: use sysfs groups to handle conditional attributesPierre Ossman2008-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Suppressing uevents turned out to be a bad idea as it screws up the order of events, making user space very confused. Change the system to use sysfs groups instead. This is a regression that, for some odd reason, has gone unnoticed for some time. It confuses hal so that the block devices (which have the mmc device as a parent) are not registered. End result being that desktop magic when cards are inserted won't work.

In 2.6.24, we increased their values to accomodate ACPI devices that have many resources: 2.6.23 2.6.24 ------ ------ PNP_MAX_MEM 4 12 PNP_MAX_PORT 8 40 However, ISAPNP also used these constants as the size of parts of the logical device register set. This register set is fixed by hardware, so increasing the constants meant that we were reading and writing unintended parts of the register set. This patch changes ISAPNP to use the correct register set sizes (the same values we used prior to 2.6.24).

This patch is only to tell lockdep that ifb is a different device (e.g. from eth) and has its own pair of queue locks. (This warning is a false-positive in common scenario of using ifb; yet there are possible situations, when this order could be dangerous; lockdep should warn in such a case.)
