The PDC202xx older devices do not support ATAPI DMA via the usual
interfaces. What documentation I have isn't sufficient to support DMA and
it isn't clear if the Windows drivers do this or it is possible at all.

There's currently no way to turn on Lguest guest support; the planned
Kconfig virtualization reorg didn't get into 2.6.25.

This was unnoticed because if you already had CONFIG_LGUEST_GUEST=y in
your config, it worked.  Too bad about new users...

Also, the Kconfig help was wrong now the virtio drivers are merged.

atl1: fix frame length bug

The driver sets up the hardware to accept a frame with max length
equal to MTU + Ethernet header + FCS + VLAN tag, but we neglect to
add the VLAN tag size to the ingress buffer.  When a VLAN-tagged
frame arrives, the hardware passes it, but bad things happen
because the buffer is too small.  This patch fixes that.

11 years agofix radeonfb regression with Xpress 200m 5955
Alex [Thu, 17 Jan 2008 23:21:18 +0000]
fix radeonfb regression with Xpress 200m 5955

Fix http://bugzilla.kernel.org/show_bug.cgi?id=9762

Framebuffer is ok only with default parameters only (it is 1280x800-8@60).  If
parameters are video=radeonfb:1280x800-32@60 then xres, yres and xres_virtual
are ok but yres_virtual is 1024.  It can be corrected by fbset utility so I
think it can be corrected in the driver code also.

Steps to reproduce: video=radeonfb:1280x800-32@60 or
video=radeonfb:1280x800-16@60

Add 1280x800 mode into modedb

11 years ago#ifdef very expensive debug check in page fault path
Carsten Otte [Thu, 17 Jan 2008 23:21:17 +0000]
#ifdef very expensive debug check in page fault path

This patch puts #ifdef CONFIG_DEBUG_VM around a check in vm_normal_page
that verifies that a pfn is valid.  This patch increases performance of the
page fault microbenchmark in lmbench by 13% and overall dbench performance
by 7% on s390x.  pfn_valid() is an expensive operation on s390 that needs a
high double digit amount of CPU cycles.  Nick Piggin suggested that
pfn_valid() involves an array lookup on systems with sparsemem, and
therefore is an expensive operation there too.

The check looks like a clear debug thing to me, it should never trigger on
regular kernels.  And if a pte is created for an invalid pfn, we'll find
out once the memory gets accessed later on anyway.  Please consider
inclusion of this patch into mm.

11 years agocpufreq: Initialise default governor before use
Johannes Weiner [Thu, 17 Jan 2008 23:21:08 +0000]
cpufreq: Initialise default governor before use

When the cpufreq driver starts up at boot time, it calls into the default
governor which might not be initialised yet.  This hurts when the
governor's worker function relies on memory that is not yet set up by its
init function.

This migrates all governors from module_init() to fs_initcall() when being
the default, as was already done in cpufreq_performance when it was the
only possible choice.  The performance governor is always initialized early
because it might be used as fallback even when not being the default.

Fixes at least one actual oops where ondemand is the default governor and
cpufreq_governor_dbs() uses the uninitialised kondemand_wq work-queue
during boot-time.

Input: mousedev - handle mice that use absolute coordinates

Devices like the HP Integrated Remote Console Virtual Mouse, which are
standard equipment on all Proliant and Integrity servers, produce
absolute coordinates instead of relative coordinates.  This is done to
synchronize the position of the mouse cursor on the client desktop
with the mouse cursor position on the server.  Mousedev is not
designed to pass those absolute events directly to X, but it can
translate them into relative movements.  It currently does this for
tablet like devices and touchpads.  This patch merely tells it to also
include a device with ABS_X, ABS_Y, and mouse buttons in its list of
devices to process input for.

This patch enables the mouse pointer to move when using the remote

lockdep: fix workqueue creation API lockdep interaction
Dave Young reported warnings from lockdep that the workqueue API
can sometimes try to register lockdep classes with the same key
but different names. This is not permitted in lockdep.

Unfortunately, I was unaware of that restriction when I wrote
the code to debug workqueue problems with lockdep and used the
workqueue name as the lockdep class name. This can obviously
lead to the problem if the workqueue name is dynamic.

This patch solves the problem by always using a constant name
for the workqueue's lockdep class, namely either the constant
name that was passed in or a string consisting of the variable
name.

Luck, Tony [Mon, 14 Jan 2008 17:59:24 +0000]
[IA64] Fix unaligned handler for floating point instructions with base update

The compiler team did the hard work for this distilling a problem in
large fortran application which showed up when applied to a 290MB input
data set down to this instruction:

ldfd f34=[r17],-8

Which they noticed incremented r17 by 0x10 rather than decrementing it
by 8 when the value in r17 caused an unaligned data fault.  I tracked
it down to some bad instruction decoding in unaligned.c. The code
assumes that the 'x' bit can determine whether the instruction is
an "ldf" or "ldfp" ... which it is for opcode=6 (see table 4-29 on
page 3:302 of the SDM).  But for opcode=7 the 'x' bit is irrelevent,
all variants are "ldf" instructions (see table 4-36 on page 3:306).

Note also that interpreting the instruction as "ldfp" means that the
"paired" floating point register (f35 in the example here) will also
be corrupted.

Fix Blackfin HARDWARE_PM support

This patch restores the blackfin Hardware Performance Monitor Profiling
support that was killed by the combining of instrumentation menus in
commit 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9.

Since there seems to be no good reason to behave differently from other
architectures, it now automatically selects the hardware performance
counters whenever the profiling is activated.

mach-common/irqpanic.c: pm_overflow calls pm_overflow_handler which is
in oprofile/op_model_bf533.c.  I doubt that setting HARDWARE_PM as "m"
will work at all, since the pm_overflow_handler should be in the core
kernel image because it is called by irqpanic.c.

Therefore, I change HARDWARE_PM from a tristate to a bool.

The whole arch/$(ARCH)/oprofile/ is built depending on CONFIG_OPROFILE. Since
part of the HARDWARE_PM support files sits in this directory, it makes sense to
also depend on OPROFILE, not only PROFILING. Since OPROFILE already depends on
PROFILING, it is correct to only depend on OPROFILE only.

Thanks to Adrian Bunk for finding this bug and providing an initial
patch.

Fix ARM profiling/instrumentation configuration

Commit 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 ("Combine
instrumentation menus in kernel/Kconfig.instrumentation") broke ARM
profiling support, since ARM has some extra Kconfig options and doesn't
just use the common OPROFILE/KPROBES config options.

Rather than just revert the thing outright, or add ARM-specific
knowledge to the generic Kconfig.instrumentation file (where the only
and whole point was to be generic, not too architecture-specific), this
just makes ARM not use the generic version, since it doesn't suit it.

So create an arm-specific version of Kconfig.instrumentation instead,
and use that.

x86: fix RTC_AIE with CONFIG_HPET_EMULATE_RTC

In the current code, RTC_AIE doesn't work if the RTC relies on
CONFIG_HPET_EMULATE_RTC because the code sets the RTC_AIE flag in
hpet_set_rtc_irq_bit().  The interrupt handles does accidentally check
for RTC_PIE and not RTC_AIE when comparing the time which was set in
hpet_set_alarm_time().

I now verified on a test system here that without the patch applied,
the attached test program fails on a system that has HPET with
2.6.24-rc7-default. That's not critical since I guess the problem has
been there for several kernel releases, but as the fix is quite
obvious.

Configuration is CONFIG_RTC=y and CONFIG_HPET_EMULATE_RTC=y.

Ingo Molnar [Tue, 15 Jan 2008 15:44:37 +0000]
x86: fix boot crash on HIGHMEM4G && SPARSEMEM

Denys Fedoryshchenko reported a bootup crash when he upgraded
his system from 3GB to 4GB RAM:

   http://lkml.org/lkml/2008/1/7/9

the bug is due to HIGHMEM4G && SPARSEMEM kernels making pfn_to_page()
to return an invalid pointer when the pfn is in a memory hole. The
256 MB PCI aperture at the end of RAM was not mapped by sparsemem,
and hence the pfn was not valid. But set_highmem_pages_init() iterated
this range without checking the pfn's validity first.

this bug was probably present in the sparsemem code ever since sparsemem
has been introduced in v2.6.13. It was masked due to HIGHMEM64G using
larger memory regions in sparsemem_32.h:

 #ifdef CONFIG_X86_PAE
 #define SECTION_SIZE_BITS       30
 #define MAX_PHYSADDR_BITS       36
 #define MAX_PHYSMEM_BITS        36
 #else
 #define SECTION_SIZE_BITS       26
 #define MAX_PHYSADDR_BITS       32
 #define MAX_PHYSMEM_BITS        32
 #endif

which creates 1GB sparsemem regions instead of 64MB sparsemem regions.
So in practice we only ever created true sparsemem holes on x86 with
HIGHMEM4G - but that was rarely used by distros.

( btw., we could probably save 2MB of mem_map[]s on X86_PAE if we reduced
  the sparsemem region size to 256 MB. )

[POWERPC] Fix boot failure on POWER6

Commit 473980a99316c0e788bca50996375a2815124ce1 added a call to clear
the SLB shadow buffer before registering it.  Unfortunately this means
that we clear out the entries that slb_initialize has previously set in
there.  On POWER6, the hypervisor uses the SLB shadow buffer when doing
partition switches, and that means that after the next partition switch,
each non-boot CPU has no SLB entries to map the kernel text and data,
which causes it to crash.

This fixes it by reverting most of 473980a9 and instead clearing the
3rd entry explicitly in slb_initialize.  This fixes the problem that
473980a9 was trying to solve, but without breaking POWER6.

[POWERPC] Workaround for iommu page alignment

Commit 5d2efba64b231a1733c4048d1708d77e07f26426 changed our iommu code
so that it always uses an iommu page size of 4kB.  That means with our
current code, drivers may do a dma_map_sg() of a 64kB page and obtain
a dma_addr_t that is only 4k aligned.

This works fine in most cases except for some infiniband HW it seems,
where they tell the HW about the page size and it ignores the low bits
of the DMA address.

This works around it by making our IOMMU code enforce a PAGE_SIZE alignment
for mappings of objects that are page aligned in the first place and whose
size is larger or equal to a page.

After 9b8e8de7, manage_start_stop configuration depends on valid ATA
device.  Move it into ata_scsi_dev_config().  This was detected by the
coverity checker.

11 years agosata_sil24: freeze on non-dev errors reported via CERR

sata_sil24: freeze on non-dev errors reported via CERR

CERR reports errors detected during executing a command.  This doesn't
mean the error is tied to the command and can be recovered by just
issuing it again.  Many of the errors are fatal port-wide connditions
including HSM violation, host bus error and ATA bus error and require
freezing and port reset.

The freezing part wasn't implemented previously.  This used to be okay
because port resets were scheduled anyway and EH eventually resets and
recovers the port.  With PMP support added, this is no longer true.
The error condition and recover actions are attributed to the fan-out
port and the host port condition isn't properly recovered leading to
EH failures.

This patch makes CERR errors which require resets to freeze the port.
This will force host port reset and proper recovery.
