* powerpc/8xx: Fixup DAR from buggy dcbX instructions.Joakim Tjernlund2009-12-09
| | | | | | | | | | This is an assembler version to fixup DAR not being set by dcbX, icbi instructions. There are two versions, one uses selfmodifing code, the other uses a jump table but is much bigger(default).

* powerpc/8xx: Tag DAR with 0x00f0 to catch buggy instructions.Joakim Tjernlund2009-12-09
| | | | | | | | | | | dcbz, dcbf, dcbi, dcbst and icbi do not set DAR when they cause a DTLB Error. Dectect this by tagging DAR with 0x00f0 at every exception exit that modifies DAR. Test for DAR=0x00f0 in DataTLBError and bail to handle_page_fault(). Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* powerpc/8xx: Update TLB asm so it behaves as linux mm expects.Joakim Tjernlund2009-12-09
| | | | | | | | | | | | | | | | | | Update the TLB asm to make proper use of _PAGE_DIRY and _PAGE_ACCESSED. Get rid of _PAGE_HWWRITE too. Pros: - I/D TLB Miss never needs to write to the linux pte. - _PAGE_ACCESSED is only set on TLB Error fixing accounting - _PAGE_DIRTY is mapped to 0x100, the changed bit, and is set directly when a page has been made dirty. - Proper RO/RW mapping of user space. - Free up 2 SW TLB bits in the linux pte(add back _PAGE_WRITETHRU ?) - kernel RO/user NA support. Cons: - A few more instructions in the TLB Miss routines. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* | | powerpc/pseries: Serialize cpu hotplug operations during deactivate Vs ↵Gautham R Shenoy2009-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | deallocate Currently the cpu-allocation/deallocation process comprises of two steps: - Set the indicators and to update the device tree with DLPAR node information. - Online/offline the allocated/deallocated CPU. This is achieved by writing to the sysfs tunables "probe" during allocation and "release" during deallocation. At the sametime, the userspace can independently online/offline the CPUs of the system using the sysfs tunable "online". It is quite possible that when a userspace tool offlines a CPU for the purpose of deallocation and is in the process of updating the device tree, some other userspace tool could bring the CPU back online by writing to the "online" sysfs tunable thereby causing the deallocate process to fail. The solution to this is to serialize writes to the "probe/release" sysfs tunable with the writes to the "online" sysfs tunable. This patch employs a mutex to provide this serialization, which is a no-op on all architectures except PPC_PSERIES Signed-off-by: Gautham R Shenoy <ego@in.ibm.com> Acked-by: Vaidyanathan Srinivasan <svaidy@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
* | | pseries/pseries: Add code to online/offline CPUs of a DLPAR nodeGautham R Shenoy2009-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the cpu-allocation/deallocation on pSeries is a two step process from the Userspace. - Set the indicators and update the device tree by writing to the sysfs tunable "probe" during allocation and "release" during deallocation. - Online / Offline the CPUs of the allocated/would_be_deallocated node by writing to the sysfs tunable "online". This patch adds kernel code to online/offline the CPUs soon_after/just_before they have been allocated/would_be_deallocated. This way, the userspace tool that performs DLPAR operations would only have to deal with one set of sysfs tunables namely "probe" and release".

There are no changes to any of the C code from v2 of the patch. In order to support kernel DLPAR of CPU resources we need to provide an interface to add (probe) and remove (release) the resource from the system. This patch Creates new generic probe and release sysfs files to facilitate cpu probe/release. The probe/release interface provides for allowing each arch to supply their own routines for implementing the backend of adding and removing cpus to/from the system. This also creates the powerpc specific stubs to handle the arch callouts from writes to the sysfs files. The creation and use of these files is regulated by the CONFIG_ARCH_CPU_PROBE_RELEASE option so that only architectures that need the capability will have the files created.

The removal of a resource involves removing the resource's node from the device tree and then returning the resource to firmware via the rtas set-indicator call. To add a resource, it is first obtained from firmware via the rtas set-indicator call and then a new device tree node is created using the ibm,configure-coinnector rtas call and added to the device tree. This patch provides the kernel DLPAR infrastructure in a new filed named dlpar.c. The functionality provided is for acquiring and releasing a resource from firmware and the parsing of information returned from the ibm,configure-connector rtas call. Additionally this exports the pSeries reconfiguration notifier chain so that it can be invoked when device tree updates are made.

In addition it's ugly and could be done better. This reworks the interface between the mediabay and the rest of the world so that: - Any macio_driver can now have a mediabay_event callback which will be called when that driver sits on a mediabay and it's been either plugged or unplugged. The device type is passed as an argument. We can now move all the IDE cruft into the IDE driver itself - A check_media_bay() function can be used to take a peek at the type of device currently in the bay if any, a cleaner variant of the previous function with the same name. - A pair of lock/unlock functions are exposed to allow the IDE driver to block the hotplug callbacks during the initial setup and probing of the bay in order to avoid nasty race conditions. - The mediabay code no longer needs to spin on the status register of the IDE interface when it detects an IDE device, this is done just fine by the IDE code itself Overall, less code, simpler, and allows for another driver than our old drivers/ide based one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit a4fe3ce7699bfe1bd88f816b55d42d8fe1dac655 introduced a new get_user_pages() path for hugepages on powerpc. Unfortunately, there is a bug in it's loop logic, which can cause it to overrun the end of the intended region. This came about by copying the logic from the normal page path, which assumes the address and end parameters have been pagesize aligned at the top-level. Since they're not *hugepage* size aligned, the simplistic logic could step over the end of the gup region without triggering the loop end condition. This patch fixes the bug by using the technique that the normal page path uses in levels above the lowest to truncate the ending address to something we know we'll match with.

Doubling the platform maximum to 1024 allows hx4700 touchscreen events to pass the test. Signed-off-by: Paul Parsons <lost.distance@yahoo.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

In such a case, PXA_IRQ(0) != 0, and the IRQ number computed from ICHP must be offset by PXA_IRQ(0). Tested on an Arcom Zeus (pxa270), with both CONFIG_PXA_HAVE_ISA_IRQS enabled and disabled.
