2009-01-03AMD IOMMU: add device detach helper functionsJoerg Roedel1-0/+39
Impact: add helper functions to detach a device from a domain Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: rename set_device_domain functionJoerg Roedel1-5/+5
Impact: rename set_device_domain() to attach_device() Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: add device reference counting for protection domainsJoerg Roedel2-1/+3
Impact: know how many devices are assigned to a domain Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: add checks for dma_ops domain to dma_ops functionsJoerg Roedel1-6/+35
Impact: detect when a driver uses a device assigned otherwise Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: add protection domain flagsJoerg Roedel2-5/+10
Imapct: add a new struct member to 'struct protection_domain' When using protection domains for dma_ops and KVM its better to know for which subsystem it was allocated. Add a flags member to struct protection domain for that purpose. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: add iommu_flush_domain functionJoerg Roedel1-0/+24
Impact: add a function to flush a domain id on every IOMMU Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: don't remove protection domain from iommu_pd_listJoerg Roedel1-1/+0
Impact: save unneeded logic to add and remove domains to the list The removal of a protection domain from the iommu_pd_list is not necessary. Another benefit is that we save complexity because we don't have to readd it later when the device no longer uses the domain. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: move invalidation command building to a separate functionJoerg Roedel1-10/+16
Impact: refactoring of iommu_queue_inv_iommu_pages Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: refactor completion wait handling into separate functionsJoerg Roedel1-23/+45
Impact: split one function into three The separate functions are required synchronize commands across all hardware IOMMUs in the system. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: add domain id free functionJoerg Roedel1-0/+12
Impact: add code to release a domain id Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: make dma_ops_free_pagetable genericJoerg Roedel1-3/+5
Impact: change code to free pagetables from protection domains The dma_ops_free_pagetable function can only free pagetables from dma_ops domains. Change that to free pagetables of pure protection domains. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03AMD IOMMU: rename iommu_map to iommu_map_pageJoerg Roedel1-5/+5
Impact: function rename The iommu_map function maps only one page. Make this clear in the function name. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03KVM: change KVM to use IOMMU APIJoerg Roedel6-6/+8
Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03select IOMMU_API when DMAR and/or AMD_IOMMU is selectedJoerg Roedel2-0/+6
These two IOMMUs can implement the current version of this API. So select the API if one or both of these IOMMU drivers is selected. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03KVM: rename vtd.c to iommu.cJoerg Roedel2-2/+2
Impact: file renamed The code in the vtd.c file can be reused for other IOMMUs as well. So rename it to make it clear that it handle more than VT-d. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03sparc: Update 64-bit defconfig.David S. Miller1-33/+72
Signed-off-by: David S. Miller <davem@davemloft.net>

2009-01-03sparc: fix warning in userspace header traps.hSam Ravnborg1-2/+2
Fix following warning: traps.h:23: extern's make no sense in userspace Add an ifdef __KERNEL__ block that cover the extern definition and a few related things that neither is for userspace. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: fix warnings in userspace header byteorder.hSam Ravnborg1-7/+5
Fix following warnings in byteorder.h: byteorder.h:4: include of <linux/types.h> is preferred over <asm/types.h> byteorder.h:9: leaks CONFIG_SPARC32 to userspace where it is not valid byteorder.h:13: leaks CONFIG_SPARC64 to userspace where it is not valid byteorder.h:14: found __[us]{8,16,32,64} type without #include <linux/types.h> byteorder.h:47: leaks CONFIG_SPARC64 to userspace where it is not valid - changed to use include <linux/types.h> as suggested - use preprocessor defined symbols to distingush between 32 and 64 bit Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: fix warning in userspace header jsflash.hSam Ravnborg1-1/+1
Fix following warnings in jsflash.h: jsflash.h:11: include of <linux/types.h> is preferred over <asm/types.h> jsflash.h:24: found __[us]{8,16,32,64} type without #include <linux/types.h> Fixed by changing the include to <linux/types.h> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: unify openprom.hSam Ravnborg4-488/+273
After the preparational steps the unification was simple. The linux_prom_pci_registers definition did not look like it could be unified at first look since the structure is assigned using prop_getproperty() / of_get_property() so the structure is assumed to come direct form the prom. The LINUX_OPPROM_MAGIC was kept even if it is not used by the kernel on the assumption that userspace may require it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc64: delete unused linux_prom64_ranges from openprom_64.hSam Ravnborg1-6/+0
It was not used over the whole tree - so drop it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: prepare openprom for unificationSam Ravnborg2-11/+11
Align the sparc and sparc64 versions so differences are minimal. A few data types are changed to better reflect there actual usage. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: remove linux_prom_pci_assigned_addresses from openprom_32.hSam Ravnborg1-10/+0
It is not used anywhere in the tree so drop it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: remove ebus definitions from openprom*.hSam Ravnborg2-37/+0
Looks like leftovers from the removal of the special ebus layer. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: unify siginfo.hSam Ravnborg4-58/+36
Trivial unification where the sparc64 specific parts are protected using a signle ifdef/endif pair. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03cris: define __flsRusty Russell1-0/+1
Like fls, but can't be handed 0 and returns the bit number. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2009-01-03sparc: unify ptrace.hSam Ravnborg4-548/+444
The two ptrace.h implementations are very alike but the small differences required two set of ifdef/else/endif pairs. The definition of reg_window32 could have been shared but that would have required several updates in sparc32 code as all printk formatting for example assume it is longs. sparc_stackf looked like anohter candidate to share if the 32 bit was renamed to sparc_stackf32. But it contains two pointers in the sparc32 version which would have been 64 bit in the sparc64 version so it was non-trivial. Using a set of accessor macros could do the trick if pursued later. The sparc64 specific definitions are not protected by ifdef - as it should not be required to do so. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: unify sigcontext.hSam Ravnborg4-155/+95
With the renamed types in place the unification was straightforward. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: add '32' suffix to reg_window, sigcontext, __siginfo_tSam Ravnborg11-41/+38
Renaming a few types to contain a 32 suffix makes the type names compatible with sparc64 and thus makes sharing between the two a lot easier. Note: None of these definitions are expected part of the stable ABI towards userspace. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: unify signal.hSam Ravnborg4-424/+207
They were almost identical and with the preapration patch nothing was needed to be added. The unified version contains a few sparc64 only definitions but they are kept as is and not protected by ifdef/endif. The unified version exports a bit more to userspace then the 32 bit version did. This is not considered fatal. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc64: prepare signal_64 for unificationSam Ravnborg1-12/+28
o add a sparc32 only definition o fix a few style issues (white space errors etc). o include compiler.h (for __user) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: Kill bogus comment about IRQF_SHARED in pci_psycho.cDavid S. Miller1-4/+1
Noticed by Geert Uytterhoeven. Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: unify stat.hSam Ravnborg4-117/+105
To my suprise struct stat64 was not equal on sparc 32 and sparc64, so there was really nothing to share here. Unify the files by adding their respective content to stat.h. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc32: use proper types in struct statSam Ravnborg1-10/+10

2009-01-03sparc32: drop __old_kernel_statSam Ravnborg1-14/+0
sparc32 does not define __ARCH_WANT_OLD_STAT so we do not use this structure neither do we support it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: unify posix_types.hSam Ravnborg4-247/+152
The posix types differed so much in their definition that they are kept in separate blocks. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-03sparc: delete unused config symbolsSam Ravnborg1-28/+0
There is no need to define a config symbol if it is never set to any value. Undefined symbols equal to 'n'. GENERIC_GPIO looks like it is similar but it is set using select in some other file so it must be kept. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
