15 years agox86: Detect use of extended APIC ID for AMD CPUs

x86: Detect use of extended APIC ID for AMD CPUs

Booting a 32-bit kernel on Magny-Cours results in the following panic:

  ...
  Using APIC driver default
  ...
  Overriding APIC driver with bigsmp
  ...
  Getting VERSION: 80050010
  Getting VERSION: 80050010
  Getting ID: 10000000
  Getting ID: ef000000
  Getting LVT0: 700
  Getting LVT1: 10000
  Kernel panic - not syncing: Boot APIC ID in local APIC unexpected (16 vs 0)
  Pid: 1, comm: swapper Not tainted 2.6.30-rcX #2
  Call Trace:
   [<c05194da>] ? panic+0x38/0xd3

   [<c073b15f>] ? kernel_init+0x0/0x141
   [<c020325f>] ? kernel_thread_helper+0x7/0x10

The reason is that default_get_apic_id handled extension of local APIC
ID field just in case of XAPIC.

Thus for this AMD CPU, default_get_apic_id() returns 0 and
bigsmp_get_apic_id() returns 16 which leads to the respective kernel
panic.

This patch introduces a Linux specific feature flag to indicate
support for extended APIC id (8 bits instead of 4 bits width) and sets
the flag on AMD CPUs if applicable.

x86: Fix UV BAU activation descriptor init

The UV tlb shootdown code has a serious initialization error.

An array of structures [32*8] is initialized as if it were [32].
The array is indexed by (cpu number on the blade)*8, so the short
initialization works for up to 4 cpus on a blade.
But above that, we provide an invalid opcode to the hub's
broadcast assist unit.

This patch changes the allocation of the array to use its symbolic
dimensions for better clarity. And initializes all 32*8 entries.

Shortened 'UV_ACTIVATION_DESCRIPTOR_SIZE' to 'UV_ADP_SIZE' per Ingo's
recommendation.

Tested on the UV simulator.

ACPI: sanity check _PSS frequency to prevent cpufreq crash

When BIOS SETUP is changed to disable EIST, some BIOS
hand the OS an un-initialized _PSS:

        Name (_PSS, Package (0x06)
        {
            Package (0x06)
            {
                0x80000000, // frequency [MHz]

                0x80000000, // control
                0x80000000 // status
            },
    ...

These are outrageous values for frequency,
power and latency, raising the question where to draw
the line between legal and illegal.  We tend to survive
garbage in the power and latency fields, but we can BUG_ON
when garbage is in the frequency field.

Cpufreq multiplies the frequency by 1000 and stores it in a u32 KHz.
So disregard a _PSS with a frequency so large
that it can't be represented by cpufreq.

mm: account for MAP_SHARED mappings using VM_MAYSHARE and not VM_SHARED in hugetlbfs

Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13302

hugetlbfs reserves huge pages but does not fault them at mmap() time to
ensure that future faults succeed.  The reservation behaviour differs
depending on whether the mapping was mapped MAP_SHARED or MAP_PRIVATE.
For MAP_SHARED mappings, hugepages are reserved when mmap() is first
called and are tracked based on information associated with the inode.
Other processes mapping MAP_SHARED use the same reservation.  MAP_PRIVATE
track the reservations based on the VMA created as part of the mmap()
operation.  Each process mapping MAP_PRIVATE must make its own
reservation.

hugetlbfs currently checks if a VMA is MAP_SHARED with the VM_SHARED flag
and not VM_MAYSHARE.  For file-backed mappings, such as hugetlbfs,
VM_SHARED is set only if the mapping is MAP_SHARED and the file was opened
read-write.  If a shared memory mapping was mapped shared-read-write for
populating of data and mapped shared-read-only by other processes, then
hugetlbfs would account for the mapping as if it was MAP_PRIVATE.  This
causes processes to fail to map the file MAP_SHARED even though it should
succeed as the reservation is there.

This patch alters mm/hugetlb.c and replaces VM_SHARED with VM_MAYSHARE
when the intent of the code was to check whether the VMA was mapped
MAP_SHARED or MAP_PRIVATE.

15 years agox86: ignore VM_LOCKED when determining if hugetlb-backed page tables can be shared...
Mel Gorman [Thu, 28 May 2009 21:34:37 +0000 (14:34 -0700)]
x86: ignore VM_LOCKED when determining if hugetlb-backed page tables can be shared or not

Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13302

On x86 and x86-64, it is possible that page tables are shared beween
shared mappings backed by hugetlbfs.  As part of this,
page_table_shareable() checks a pair of vma->vm_flags and they must match
if they are to be shared.  All VMA flags are taken into account, including
VM_LOCKED.

The problem is that VM_LOCKED is cleared on fork().  When a process with a
shared memory segment forks() to exec() a helper, there will be shared
VMAs with different flags.  The impact is that the shared segment is
sometimes considered shareable and other times not, depending on what
process is checking.

What happens is that the segment page tables are being shared but the
count is inaccurate depending on the ordering of events.  As the page
tables are freed with put_page(), bad pmd's are found when some of the
children exit.  The hugepage counters also get corrupted and the Total and
Free count will no longer match even when all the hugepage-backed regions
are freed.  This requires a reboot of the machine to "fix".

This patch addresses the problem by comparing all flags except VM_LOCKED
when deciding if pagetables should be shared or not for hugetlbfs-backed
mapping.

an edit to i7300_idle.h to "#define SUPPORT_I5000 1" and a re-build

Replace that build-time scheme with a load-time module parameter:

usb-serial: fix crash when sub-driver updates firmware

This patch (as1244) fixes a crash in usb-serial that occurs when a
sub-driver returns a positive value from its attach method, indicating
that new firmware was loaded and the device will disconnect and
reconnect.  The usb-serial core then skips the step of registering the
port devices; when the disconnect occurs, the attempt to unregister
the ports fails dramatically.

This problem shows up with Keyspan devices and it might affect others
as well.

When the attach method returns a positive value, the patch sets
num_ports to 0.  This tells usb_serial_disconnect() not to try
unregistering any of the ports; instead they are cleaned up by
destroy_serial().

(original patch from Catalin Marinas <catalin.marinas@arm.com>)

The cmpxchg and cmpxchg64 functions can be implemented using the
LDREX*/STREX* instructions. Since operand lengths other than 32bit are
required, the full implementations are only available if the ARMv6K
extensions are present (for the LDREXB, LDREXH and LDREXD instructions).

For ARMv6, only 32-bits cmpxchg is available.

Mathieu :

Make cmpxchg_local always available with best implementation for all type sizes (1, 2, 4 bytes).
Make cmpxchg64_local always available.

Use "Ir" constraint for "old" operand, like atomic.h atomic_cmpxchg does.

Change since v3 :
- Add "memory" clobbers (thanks to Nicolas Pitre)
- removed __asmeq(), only needed for old compilers, very unlikely on ARMv6+.

Note : ARMv7-M should eventually be ifdefed-out of cmpxchg64. But it's not
supported by the Linux kernel currently.

Put back arm < v6 cmpxchg support.

svcrdma: dma unmap the correct length for the RPCRDMA header page.

The svcrdma module was incorrectly unmapping the RPCRDMA header page.
On IBM pserver systems this causes a resource leak that results in
running out of bus address space (10 cthon iterations will reproduce it).
The code was mapping the full page but only unmapping the actual header
length.  The fix is to only map the header length.

I also cleaned up the use of ib_dma_map_page() calls since the unmap
logic always uses ib_dma_unmap_single().  I made these symmetrical.

15 years agonfsd: fix hung up of nfs client while sync write data to nfs server

nfsd: fix hung up of nfs client while sync write data to nfs server

Commit 'Short write in nfsd becomes a full write to the client'
(31dec2538e45e9fff2007ea1f4c6bae9f78db724) broken the sync write.
With the following commands to reproduce:

  $ mount -t nfs -o sync 192.168.0.21:/nfsroot /mnt
  $ cd /mnt
  $ echo aaaa > temp.txt

Then nfs client is hung up.

In SYNC mode the server alaways return the write count 0 to the
client. This is because the value of host_err in nfsd_vfs_write()
will be overwrite in SYNC mode by 'host_err=nfsd_sync(file);',
and then we return host_err(which is now 0) as write count.

This patch fixed the problem.

i915: Set object to gtt domain when faulting it back in

When a GEM object is evicted from the GTT we set it to the CPU domain,
as it might get swapped in and out or ever mmapped regularly.  If the
object is mmapped through the GTT it can still get evicted in this way
by other objects requiring GTT space.  When the GTT mapping is touched
again we fault it back into the GTT, but fail to set it back to the
GTT domain.  This means we fail to flush any cached CPU writes to the
pages backing the object which will then happen "eventually", typically
after we write to the page through the uncached GTT mapping.

[anholt: Note that userland does do a set_domain(GTT, GTT) when starting
to access the GTT mapping.  That covers getting the existing mapping of the
object synchronized if it's bound to the GTT.  But set_domain(GTT, GTT)
doesn't do anything if the object is currently unbound.  This fix covers the
transition to being bound for GTT mapping.]
