one of my boxes didnt boot the 2.6.20-rc1-rt0 kernel rpm, it hung during early bootup. After an hour or two of happy debugging i narrowed it down to the CALGARY_IOMMU_ENABLED_BY_DEFAULT option, which was freshly added to 2.6.20 via the x86_64 tree and /enabled by default/. commit bff6547b claims: [PATCH] Calgary: allow compiling Calgary in but not using it by default This patch makes it possible to compile Calgary in but not use it by default. In this mode, use 'iommu=calgary' to activate it. but the change does not actually practice it: config CALGARY_IOMMU_ENABLED_BY_DEFAULT bool "Should Calgary be enabled by default?" default y depends on CALGARY_IOMMU help Should Calgary be enabled by default? if you choose 'y', Calgary will be used (if it exists). If you choose 'n', Calgary will not be used even if it exists. If you choose 'n' and would like to use Calgary anyway, pass 'iommu=calgary' on the kernel command line. If unsure, say Y. it's both 'default y', and says "If unsure, say Y". Clearly not a typo. disabling this option makes my box boot again. The patch below fixes the Kconfig entry. Grumble.

libata depended on SCSI command to have the correct length when tranlating it into an ATA command. This generally worked for commands issued by SCSI HLD but user could issue arbitrary broken command using sg interface. Also, when building ATAPI command, full command size was always copied. Because some ATAPI devices needs bytes after CDB cleared, if upper layer doesn't clear bytes after CDB, such devices will malfunction. This necessiated recent clear-garbage-after-CDB fix in sg interfaces. However, scsi_execute() isn't fixed yet and HL-DT-ST DVD-RAM GSA-H30N malfunctions on initialization commands issued from SCSI. This patch makes xlat functions always consider SCSI cmd_len. Each translation function checks for proper cmd_len and ATAPI translaation clears bytes after CDB. Signed-off-by:

xlat function will be updated to consider qc->scsicmd->cmd_len and many xlat functions deference qc->scsicmd already. It doesn't make sense to pass qc->scsicmd->cmnd as @cdb separately. Kill the argument. Signed-off-by:

Tejun Heo authored
Variable names in xlat functions are quite confusing now. 'scsicmd' is used for CDB while qc->scsicmd points to struct scsi_cmnd while 'cmd' is used for struct scsi_cmnd. This patch cleans up variable names in xlat functions such that 'scmd' is used for struct scsi_cmnd and 'cdb' for CDB. Also, 'scmd' local variable is added if qc->scsicmd is used multiple times.

Since commit 368c73d4 the kernel will try to update the non-writeable BAR registers 0..3 of PIIX4 IDE adapters if pci_assign_unassigned_resources() is used to do full resource assignment of the bus. This fails because in the PIIX4 these BAR registers have implicitly assumed values and read back as zero; it used to work because the kernel used to just write zero to that register the read back value did match what was written. The fix is a new resource flag IORESOURCE_PCI_FIXED used to mark a resource as non-movable. This will also be useful to keep other import system resources from being moved around - for example system consoles on PCI busses. [akpm@osdl.org: cleanup] Signed-off-by:

This patch is designed to fix: - Disk eating corruptor on KT7 after resume from RAM - VIA IRQ handling - VIA fixups for bus lockups after resume from RAM The core of this is to add a table of resume fixups run at resume time. We need to do this for a variety of boards and features, but particularly we need to do this to get various critical VIA fixups done on resume. The second part of the problem is to handle VIA IRQ number rules which are a bit odd and need special handling for PIC interrupts. Various patches broke various boxes and while this one may not be perfect (hopefully it is) it ensures the workaround is applied to the right devices only. From: Jean Delvare <khali@linux-fr.org> Now that PCI quirks are replayed on software resume, we can safely re-enable the Asus SMBus unhiding quirk even when software suspend support is enabled.

Michael Ellerman authored
There are already several places in the kernel that want to search a PCI device for a given Hypertransport capability. Although this is possible using pci_find_capability() etc., it makes sense to encapsulate that logic in a helper - pci_find_ht_capability(). To cater for searching exhaustively for a capability, we also provide pci_find_next_ht_capability(). We also need to cater for the fact that the HT capability fields may be either 3 or 5 bits wide. pci_find_ht_capability() deals with this for you, but callers using the #defines directly must handle that themselves.

Michael Ellerman authored
The current implementation of __pci_bus_find_cap() does two things, first it determines the start of the capability chain for the device, and then it trys to find the requested capability. Split these out, so that we can use the two parts independantly in a subsequent patch. Externally visible behaviour should be unchanged. Signed-off-by:

This works like pci_dev_present but instead of returning boolean returns the matching pci_device_id entry. This makes it much more useful. Code bloat is basically nil as the old boolean function is rewritten in terms of the new one. This will be used by the updated VIA PCI quirks for one Signed-off-by:
