This is a minor patch to the ppc64 PCI hotplug code; it makes the call to rpaphp_unconfig_pci_adapter() symmetric with respect to the call to rpaphp_config_pci_adapter(). I discussed this with John Rose, who had provided the last round of changes for these functions; he appearently had this patch but somehow failed to mail it out. Tested. (added/removed device).

Add pci_{enable,disable}_device() calls. Without pci_enable_device(), dev->irq is garbage, and cpqphp relies on it. This fixes a problem reported by Bruno Redondi.

Cleanup the need_restore switch statement in pci_set_power_state(). This makes it more safe by explicitly handling all the PCI power states instead of handling them as the default case.

IPR scsi adapter have an exposure today in that they issue BIST to the adapter to reset the card. If, during the time it takes to complete BIST, userspace attempts to access PCI config space, the host bus bridge will master abort the access since the ipr adapter does not respond on the PCI bus for a brief period of time when running BIST. On PPC64 hardware, this master abort results in the host PCI bridge isolating that PCI device from the rest of the system, making the device unusable until Linux is rebooted. This patch makes use of some newly added PCI layer APIs that allow for protection from userspace accessing config space of a device in scenarios such as this.

Some PCI adapters (eg. ipr scsi adapters) have an exposure today in that they issue BIST to the adapter to reset the card. If, during the time it takes to complete BIST, userspace attempts to access PCI config space, the host bus bridge will master abort the access since the ipr adapter does not respond on the PCI bus for a brief period of time when running BIST. On PPC64 hardware, this master abort results in the host PCI bridge isolating that PCI device from the rest of the system, making the device unusable until Linux is rebooted. This patch is an attempt to close that exposure by introducing some blocking code in the PCI code. When blocked, writes will be humored and reads will return the cached value. Ben Herrenschmidt has also mentioned that he plans to use this in PPC power management.

Add PEC support to the lm90 driver. Only the ADM1032 chip supports it, and in a rather tricky way, which is why this patch comes with documentation reinforcements. At least, this demonstrates that the new PEC support logic in i2c-core can properly deal with chips with partial PEC support. As enabling PEC causes a significant performance drop, it can be disabled through a sysfs file (unsurprisingly named "pec").

This is my rewrite of the SMBus PEC support. The original implementation was known to have bugs (credits go to Hideki Iwamoto for reporting many of them recently), and was incomplete due to a conceptual limitation. The rewrite affects only software PEC. Hardware PEC needs very little code and is mostly untouched. Technically, both implementations differ in that the original one was emulating PEC in software by modifying the contents of an i2c_smbus_data union (changing the transaction to a different type), while the new one works one level lower, on i2c_msg structures (working on message contents). Due to the definition of the i2c_smbus_data union, not all SMBus transactions could be handled (at least not without changing the definition of this union, which would break user-space compatibility), and those which could had to be implemented individually. At the opposite, adding PEC to an i2c_msg structure can be done on any SMBus transaction with common code. Advantages of the new implementation: * It's about twice as small (from ~136 lines before to ~70 now, only counting i2c-core, including blank and comment lines). The memory used by i2c-core is down by ~640 bytes (~3.5%). * Easier to validate, less tricky code. The code being common to all transactions by design, the risk that a bug can stay uncovered is lower. * All SMBus transactions have PEC support in I2C emulation mode (providing the non-PEC transaction is also implemented). Transactions which have no emulation code right now will get PEC support for free when they finally get implemented. * Allows for code simplifications in header files and bus drivers (patch follows). Drawbacks (I guess there had to be at least one): * PEC emulation for non-PEC capable non-I2C SMBus masters was dropped. It was based on SMBus tricks and doesn't quite fit in the new design. I don't think it's really a problem, as the benefit was certainly not worth the additional complexity, but it's only fair that I at least mention it. Lastly, let's note that the new implementation does slightly affect compatibility (both in kernel and user-space), but doesn't actually break it. Some defines will be dropped, but the code can always be changed in a way that will work with both the old and the new implementations. It shouldn't be a problem as there doesn't seem to be many users of SMBus PEC to date anyway. Signed-off-by: NJean Delvare <khali@linux-fr.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>
