14 years agoFix handling of the HP/Acer 'DMAR at zero' BIOS error for machines with <4GiB RAM.
David Woodhouse [Thu, 19 Nov 2009 02:18:44 +0000 (02:18 +0000)]
Fix handling of the HP/Acer 'DMAR at zero' BIOS error for machines with <4GiB RAM.

Commit 86cf898e1d0fca245173980e3897580db38569a8 ("intel-iommu: Check for
'DMAR at zero' BIOS error earlier.") was supposed to work by pretending
not to detect an IOMMU if it was actually being reported by the BIOS at
physical address zero.

However, the intel_iommu_init() function is called unconditionally, as
are the corresponding functions for other IOMMU hardware.

So the patch only worked if you have RAM above the 4GiB boundary. It
caused swiotlb to be initialised when no IOMMU was detected during early
boot, and thus the later IOMMU init would refuse to run.

But if you have less RAM than that, swiotlb wouldn't get set up and the
IOMMU _would_ still end up being initialised, even though we never
claimed to detect it.

This patch also sets the dmar_disabled flag when the error is detected
during the initial detection phase -- so that the later call to
intel_iommu_init() will return without doing anything, regardless of
whether swiotlb is used or not.

[CPUFREQ] Fix stale cpufreq_cpu_governor pointer

Dave,

Attached is an update of my patch against the cpufreq fixes branch.

Before applying the patch I compiled and booted the tree to see if the panic
was still there -- to my surprise it was not.  This is because of the conversion
of cpufreq_cpu_governor to a char[].

While the panic is kaput, the problem of stale data continues and my patch is
still valid.  It is possible to end up with the wrong governor after hotplug
events because CPUFREQ_DEFAULT_GOVERNOR is statically linked to a default,
while the cpu siblings may have had a different governor assigned by a user.

ie) the patch is still needed in order to keep the governors assigned
properly when hotplugging devices

Allow memory hotplug and hibernation in the same kernel

Memory hotplug and hibernation were exclusive in Kconfig.  This is
obviously a problem for distribution kernels who want to support both in
the same image.

After some discussions with Rafael and others the only problem is with
parallel memory hotadd or removal while a hibernation operation is in
process.  It was also working for s390 before.

This patch removes the Kconfig level exclusion, and simply makes the
memory add / remove functions grab the pm_mutex to exclude against
hibernation.

Fixes a regression - old kernels didn't exclude memory hotadd and
hibernation.

binary interface.  The storage area for URB data is divided into
fixed-size blocks.  If an URB's data can't be copied, the area
reserved for it should be decreased to the size of the truncated
information (rounded up to a block boundary).  Rounding up the amount
to be removed and subtracting it from the reserved size is definitely
the wrong thing to do.

Also, when the data for an isochronous URB can't be copied, we can
still copy the isoc packet descriptors.  In fact the current code does
copy the descriptors, but then sets the capture length to 0 so they
remain inaccessible.  The capture length should be reduced to the
length of the descriptors, not set to 0.

USB: xhci: Fix TRB physical to virtual address translation.

The trb_in_td() function in the xHCI driver is supposed to translate a
physical transfer buffer request (TRB) into a virtual pointer to the ring
segment that TRB is in.

Unfortunately, a mistake in this function may cause endless loops as the
driver searches through the linked list of ring segments over and over
again.  Fix a couple bugs that may lead to loops or bad output:

1. Bail out if we get a NULL pointer when translating the segment's
private structure and the starting DMA address of the segment chunk.  If
this happens, we've been handed a starting TRB pointer from a different
ring.

2. Make sure the function works when there's multiple segments in the
ring.  In the while loop to search through the ring segments, use the
current segment variable (cur_seg), rather than the starting segment
variable (start_seg) that is passed in.

3. Stop searching the ring if we've run through all the segments in the
ring.

I have the same problem with cdc-acm (I'm using a Samsung SGH-U900): when I
unplug it from the USB port during a PPP connection, the ppp daemon gets the
hangup correctly (and closes the device), but the struct acm corresponding to
the device disconnected is not freed. Hence reconnecting the device results in
creation of /dev/ttyACM(x+1). The same happens when the system is hibernated
during a PPP connection.

This memory leak is due to the fact that when the tty is hung up,
tty_port_close_start() returns always zero, and acm_tty_close() never reaches
the point where acm_tty_unregister() is called.

Here is a fix for this.

omap3: clock: Fix the DPLL freqsel computations

Fix the freqsel value computation. Use n instead of (n+1)

The formula in the TRM uses a zero-based N, hence the (n+1); however
at this point in the clock34xx.c code, N is one-based.

Hayati Bayrakdar <h-bayrakdar@ti.com> and Nishanth Menon <nm@ti.com> helped

14 years agoxfs: copy li_lsn before dropping AIL lock
Nathaniel W. Turner [Mon, 16 Nov 2009 19:51:48 +0000 (19:51 +0000)]
xfs: copy li_lsn before dropping AIL lock

Access to log items on the AIL is generally protected by m_ail_lock;
this is particularly needed when we're getting or setting the 64-bit
li_lsn on a 32-bit platform.  This patch fixes a couple places where we
were accessing the log item after dropping the AIL lock on 32-bit
machines.

This can result in a partially-zeroed log->l_tail_lsn if
xfs_trans_ail_delete is racing with xfs_trans_ail_update, and in at
least some cases, this can leave the l_tail_lsn with a zero cycle
number, which means xlog_space_left will think the log is full (unless
CONFIG_XFS_DEBUG is set, in which case we'll trip an ASSERT), leading to
processes stuck forever in xlog_grant_log_space.

Thanks to Adrian VanderSpek for first spotting the race potential and to
Dave Chinner for debug assistance.

XFS bug in log recover with quota (bugzilla id 855)

Hi,
I was hit by a bug in linux 2.6.31 when XFS is not able to recover the
log after a crash if fs was mounted with quotas. Gory details in XFS
bugzilla: http://oss.sgi.com/bugzilla/show_bug.cgi?id=855.

It looks like wrong struct is used in buffer length check, and the following
patch should fix the problem.

xfs_dqblk_t has a size of 104+32 bytes, while xfs_disk_dquot_t is 104 bytes
long, and this is exactly what I see in system logs - "XFS: dquot too small
(104) in xlog_recover_do_dquot_trans."
