| | | | | | | | | | | | | | | | | | | | | | | | | | Patch to add VIA PCI quirk for Enhanced/Extended USB on VT8235 southbridge. It is needed in order to use EHCI/USB 2.0 with ACPI. Without it IRQs are not routed correctly, you get an "Unlink after no-IRQ?" error and the device is unusable. I belive this could also be a fix for Bugzilla Bug 5835.

* | [PATCH] x86: increase MAX_MP_BUSSES on default archAndrew Morton2006-09-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Vitezslav Samel <samel@mail.cz> reports that an HP DL380 g4 fails using the default arch due to the ISA bus having an ID of 32. It would have worked OK with the generic arch - for some reason the default arch doesn't support as many busses. So bump that up to support 256 busses, but leave it at 32 if we're building a tiny system to save a bit of memory.

* | [PATCH] task delay accounting fixesShailabh Nagar2006-09-012-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Cleanup allocation and freeing of tsk->delays used by delay accounting. This solves two problems reported for delay accounting: 1. oops in __delayacct_blkio_ticks http://www.uwsg.indiana.edu/hypermail/linux/kernel/0608.2/1844.html Currently tsk->delays is getting freed too early in task exit which can cause a NULL tsk->delays to get accessed via reading of /proc/<tgid>/stats. The patch fixes this problem by freeing tsk->delays closer to when task_struct itself is freed up. As a result, it also eliminates the use of tsk->delays_lock which was only being used (inadequately) to safeguard access to tsk->delays while a task was exiting. 2. Possible memory leak in kernel/delayacct.c http://www.uwsg.indiana.edu/hypermail/linux/kernel/0608.2/1389.html The patch cleans up tsk->delays allocations after a bad fork which was missing earlier. The patch has been tested to fix the problems listed above and stress tested with rapid calls to delay accounting's taskstats command interface (which is the other path that can access the same data, besides the /proc interface causing the oops above).

* | [PATCH] ZVC: Scale thresholds depending on the size of the systemChristoph Lameter2006-09-011-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ZVC counter update threshold is currently set to a fixed value of 32. This patch sets up the threshold depending on the number of processors and the sizes of the zones in the system. With the current threshold of 32, I was able to observe slight contention when more than 130-140 processors concurrently updated the counters. The contention vanished when I either increased the threshold to 64 or used Andrew's idea of overstepping the interval (see ZVC overstep patch). However, we saw contention again at 220-230 processors. So we need higher values for larger systems. But the current default is already a bit of an overkill for smaller systems. Some systems have tiny zones where precision matters. For example i386 and x86_64 have 16M DMA zones and either 900M ZONE_NORMAL or ZONE_DMA32. These are even present on SMP and NUMA systems. The patch here sets up a threshold based on the number of processors in the system and the size of the zone that these counters are used for. The threshold should grow logarithmically, so we use fls() as an easy approximation. Results of tests on a system with 1024 processors (4TB RAM) The following output is from a test allocating 1GB of memory concurrently on each processor (Forking the process. So contention on mmap_sem and the pte locks is not a factor): X MIN TYPE: CPUS WALL WALL SYS USER TOTCPU fork 1 0.552 0.552 0.540 0.012 0.552 fork 4 0.552 0.548 2.164 0.036 2.200 fork 16 0.564 0.548 8.812 0.164 8.976 fork 128 0.580 0.572 72.204 1.208 73.412 fork 256 1.300 0.660 310.400 2.160 312.560 fork 512 3.512 0.696 1526.836 4.816 1531.652 fork 1020 20.024 0.700 17243.176 6.688 17249.863 So a threshold of 32 is fine up to 128 processors. At 256 processors contention becomes a factor. Overstepping the counter (earlier patch) improves the numbers a bit: fork 4 0.552 0.548 2.164 0.040 2.204 fork 16 0.552 0.548 8.640 0.148 8.788 fork 128 0.556 0.548 69.676 0.956 70.632 fork 256 0.876 0.636 212.468 2.108 214.576 fork 512 2.276 0.672 997.324 4.260 1001.584 fork 1020 13.564 0.680 11586.436 6.088 11592.523 Still contention at 512 and 1020.

| * [POWERPC] Fix problem with time not advancing on 32-bit platformsPaul Mackerras2006-08-301-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a problem introduced in 5db9fa9593e2ff69f2b95f9d59229dc4faaa564d. The last_jiffy per-cpu variable is only 32 bits on 32-bit machines, but it was being compared with a 64-bit quantity (tb_next_jiffy), which resulted in time not advancing. This fixes it by changing last_jiffy to be 64 bits on all platforms. With this, we no longer need tb_last_stamp as a 32-bit version of tb_last_jiffy, so this gets rid of tb_last_stamp and we just use tb_last_jiffy instead. This also fixes a bug when the boot cpu is not online, because using tb_last_stamp could have caused the wrong timebase origin value to be used when calculating the time of day.

| | | | | | | | | | | | | | | | | | | | | | | | Device-tree bugs on js20 with some versions of SLOF were causing the interrupt for IDE to not be parsed correctly and fail to boot. This patch adds a bit more sanity checking to the parser to detect some of those errors and fail instead of returning bogus information.

| * [POWERPC] Support for "weird" MPICs and fixup mpc7448_hpc2Zang Roy-r619112006-08-301-0/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new hardware information table for mpic. This enables the mpic code to deal with mpic controllers with different register layouts and hardware behaviours. This introduces CONFIG_MPIC_WEIRD. For boards with non standard mpic controllers, select CONFIG_MPIC_WEIRD and add its hardware information in the mpic_infos[] array. TSI108/109 PIC takes the first index of weird hardware information table. :) The table can be extended. The Tsi108/109 PIC looks like standard OpenPIC but, in fact, is different in register mapping and behavior. The patch does not affect the behavior of standard mpic. If CONFIG_MPIC_WEIRD is not defined, the code is essentially identical to the current code. [benh@kernel.crashing.org: This patch is a slightly cleaned up version of Zang Roy's support for the TSI108 MPIC variant. It also fixes up MPC7448_hpc2 to use the new version of the type macros and changes the way MPIC is selected in Kconfig to better match what is done for other system devices. ] Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a hang on ppc32. The problem was that I was comparing a 32-bit quantity with a 64-bit quantity, and consequently time wasn't advancing. This makes us use a 64-bit quantity on all platforms, which ends up simplifying the code since we can now get rid of the tb_last_stamp variable (which actually fixes another bug that Ben H and I noticed while going carefully through the code). This works fine on my G4 tibook. Let me know how it goes on your machines.

With CONFIG_SLAB_DEBUG, its possible for an allocation to cross the page boundary causing IO problems. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200127 So, instead of allocating these from regular slabs - manage allocation from its own slabs and disable slab debug for these slabs.

* | | | [PATCH] vcsa attribute bits -> ioctl(VT_GETHIFONTMASK)Samuel Thibault2006-08-272-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When reading /dev/vcsa while a font with more than 256 characters is loaded, one of the attribute bits records the 9th bit of the character. But depending on the console driver (vgacon or fbcon for instance), that's bit 3 or bit 0. And there is no way for userland to know that, thus no way for userland to safely grab the screen content. So here is a (tested) patch: Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC text (vc_hi_font_mask field of the vc_data structure).

It is very very difficult to allocte this much contiguous memory and it turns out we never even use it. We really only need a couple of pages, so this patch has us allocates just what we know what we need today. Later if vendors start adding vendor specific data and we need to handle large buffers we can do this, but for the last 4 years we have not seen anyone do this or request it.

| * | | [SCSI] iscsi bugfixes: fix oops when iser is flushing ioMike Christie2006-07-281-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we enter recovery and flush the running commands we cannot freee the connection before flushing the commands. Some commands may have a reference to the connection that needs to be released before. iscsi_stop was forcing the term and suspend too early and was causing a oops in iser, so this patch removes those callbacks all together and allows the LLD to handle that detail.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Abort handler fixes. If a connection is dropped and reconnected while an abort is running then we should assume the recovery code will clean up the abort. Not doing so causes a oops. And if a command completes then we get the status for the abort, we do not need to call into the LLD to cleanup the resources. Doing this causes and oops in iser because it ends up freeing some resources twice. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

This can result in the task being queued on the xmit queue but gettting completed at the same time. This patch fixes the above bug by making the fifo a list so we always remove the entry on the list del.

Teach the RPC client to avoid using that port by raising the default minimum port number to 665. Test plan: Find a mainboard known to use port 664 for IPMI; enable IPMI; mount NFS servers in a tight loop.
