| * x86/amd-iommu: Initialize passthrough mode when requestedJoerg Roedel2009-09-03
| | | | | | | | | | | | | | | | This patch enables the passthrough mode for AMD IOMMU by running the initialization function when iommu=pt is passed on the kernel command line. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
| * x86/amd-iommu: Don't detach device from pt domain on driver unbindJoerg Roedel2009-09-03
| | | | | | | | | | | | | | | | This patch makes sure a device is not detached from the passthrough domain when the device driver is unloaded or does otherwise release the device. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
| * x86/amd-iommu: Make sure a device is assigned in passthrough modeJoerg Roedel2009-09-03
| | | | | | | | | | | | | | | | | | When the IOMMU driver runs in passthrough mode it has to make sure that every device not assigned to an IOMMU-API domain must be put into the passthrough domain instead of keeping it unassigned. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
| * x86/amd-iommu: Align locking between attach_device and detach_deviceJoerg Roedel2009-09-03
| | | | | | | | | | | | | | | | This patch makes the locking behavior between the functions attach_device and __attach_device consistent with the locking behavior between detach_device and __detach_device. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
| * x86/amd-iommu: Fix device table write orderJoerg Roedel2009-09-03
| | | | | | | | | | | | | | The V bit of the device table entry has to be set after the rest of the entry is written to not confuse the hardware. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
| * x86/amd-iommu: Add passthrough mode initialization functionsJoerg Roedel2009-09-03
| | | | | | | | | | | | | | | | | | When iommu=pt is passed on kernel command line the devices should run untranslated. This requires the allocation of a special domain for that purpose. This patch implements the allocation and initialization path for iommu=pt. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
| * x86/amd-iommu: Add core functions for pd allocation/freeingJoerg Roedel2009-09-03
| | | | | | | | | | | | | | | | | | This patch factors some code of protection domain allocation into seperate functions. This way the logic can be used to allocate the passthrough domain later. As a side effect this patch fixes an unlikely domain id leakage bug. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

This driver is used on most netbooks (no AHCI for cheap storage it seems). The scan is the dominating time factor in the kernel boot for these devices; with this flag it gets cut in half for the device I used for testing (eeepc). Alan took a look at the driver source and concluded that it ought to be safe to do for this driver. Alan has also checked with the hardware team. and it is all true but once we put all things together additional constraints for PATA controllers show up (some hardware registers have per-host not per-port atomicity) and we risk misprogramming the controller. I used the following test to check whether the issue is real: @@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_ (timings[pio][1] << 8); } pci_write_config_word(dev, master_port, master_data); - if (is_slave) + if (is_slave) { + if (ap->port_no == 0) { + u8 tmp = slave_data; + + while (slave_data == tmp) { + pci_read_config_byte(dev, slave_port, &tmp); + msleep(50); + } + + dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan " + "race detected\n"); + } pci_write_config_byte(dev, slave_port, slave_data); + } /* Ensure the UDMA bit is off - it will be turned back on if UDMA is selected */ and it indeed triggered the error message. Lets fix all such races by adding an extra locking to ->set_piomode and ->set_dmamode methods for PATA controllers. [ Alan: would be better to take the host lock in libata-core for these cases so that we fix all the adapters in one swoop.

But if there are multiple objects inactive, then they don't have seqnos and the first fence reg among them would be chosen.

| * | | ACPICA: Windows compatibility fix: same buffer/string storeLin Ming2009-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a compatibility issue when the same buffer or string is stored to itself. This has been seen in the field. Previously, ACPICA would zero out the buffer/string. Now, the operation is treated as a NOP. http://bugzilla.acpica.org/show_bug.cgi?id=803 Reported-by: Rezwanul Kabir <Rezwanul_Kabir@Dell.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
