PHKL_27054:
( SR:8606223938 CR:JAGad93033 )
CPU migration on non-Superdome cellular systems will cause
floating CPUs to become lost between the vPar monitor and
the kernel. CPUs will leave the monitor and be reported as
unavailable by the vpar* commands, but tools such as top(1)
run on the owning vPar will not show the CPU.
PHKL_25166:

PHKL_23609:
( SR:8606169455 CR:JAGad38730 )
Some Superdome machines randomly panic very early in the
boot process.
PHKL_30288:
( SR:8606337549 CR:JAGae98556 )
A multi-threaded user application using Light Weight
Process (LWP) threads might experience an unkillable hang
after a thread is asynchronously canceled. This is more
likely to occur on a uniprocessor system but can also
happen on a multiprocessor system.
PHKL_25842:
( SR:8606229034 CR:JAGad98088 )
Enhancement to provide support for the interruption of a
specic thread blocked interruptibly in a system call.
Defect Description:
PHKL_34311:
( SR:8606425727 CR:JAGaf85235 )
A thread performing a process-wide operation like fork()
needs to suspend all other threads in the process. If this
causes a 'ready to run' thread to be suspended, which may
be holding some kernel resource, it will cause another
thread waiting non-interruptably for that kernel resource
to be blocked indefinitely, without getting suspended.
This will cause the first thread performing process-wide
operation to block forever too. This will result in a
process hang.
Resolution:
Mark threads exiting the trap and system call paths safe
for suspension.
PHKL_32005:
( SR:8606299086 CR:JAGae62582 )
In patch PHKL_32002, device I/O operations uses dynamically
allocated buffers instead of using statically allocated
buffers. This statically allocated buffer pool is no longer
used which results in a wastage of approximately 96KB of
memory per cpu on the system.
Resolution:
Device I/O buffer pools are not allocated since they are
not used after PHKL_32002 installation. Absence of this
patch will have no other impact on the system.
PHKL_30954:
( SR:8606362747 CR:JAGaf23412 )
When the kernel needs to copy memory to or from user
space, the function copyin() is used. If the starting
source address is unaligned (not aligned to a 4-byte
memory boundary), copyin() rounds the address down to a
word-aligned address and then uses the ldw instruction
to load one word of the source data. If the virtual
memory translation for the source page is not present, a
data page fault will occur causing the function
check_caught_trap() to be called to check if the faulting
address is within the range of memory that copyin() was
attempting to access. Because the fault address can be
up to 3 bytes before the actual source address that was
passed to copyin(), check_caught_trap() would consider
the address to be outside of the expected range and panic
with the message "Caught trap was not ours".
Resolution:
The function check_caught_trap() was modified so that it
considers the double word (8-byte) aligned address of the
starting address to be be inside the copy range.
PHKL_30606:
( SR:8606321509 CR:JAGae83977 )
This product update contains support required to
enable the HP-UX Detect and Strobe.
Resolution:
EIRR bit mask generation for Detect and Strobe
feature.
( SR:8606331405 CR:JAGae92525 )
Each bit in the EIRR register represents a set of
interrupts. The order in which the interrupts are
processed is from MSB (most significant bit) to
LSB (least significant bit). So, if a higher order
bit is asserted continuously, the interrupts
corresponding to lower order bits my be starved.
Resolution:
Interrupt processing is changed to use round robin
algorithm.
PHKL_30286:
( SR:8606334497 CR:JAGae95577 )
When a LWP thread is aborted by a pthread_cancel, a side
effect of is that the aborting thread may execute briefly
before being aborted completely. The thread may return to
user space and execute user program code during this brief
interval. Depending on what the user program does during
that period, unexpected, detrimental effects to the system
could result. For instance, the program could immediately
perform another system call where a semaphore or other
global resources could be acquired and cause the thread to
become unkillable, lead to a system deadlock/hang, etc.
Resolution:
The fix is to create a new function that will handle the
aborting thread instead of letting it get rescheduled.
Check the condition in the trap path where a thread returns
to user space from the kernel to ensure that an aborted
thread does not return to user space.
PHKL_30100:
( SR:8606218037 CR:JAGad87187 )
In the event of an LPMC or unexpected interrupt during the
early boot path, HP-UX 64bit kernels will incorrectly
collect interrupt save state for PA-RISC 1.x processors.
Resolution:
HP-UX 64bit kernels will always collect interrupt save
state for PA-RISC 2.0 processors by setting a static flag
in the kernel binary.
PHKL_29889:
( SR:8606330496 CR:JAGae91619 )
This happens on large memory systems due to
unavailability of 32-bit kernel virtual addresses.
DLKM needs 32-bit kernel virtual addresses to load
the module, but these addresses are already
taken by kernel data structures.
Resolution:
This patch provides the functionality of reserving
32-bit kernel virtual addresses, when installed with
patch PHKL_29890. If PHKL_29890 is not installed
this patch will not have any effect.
PHKL_27766:
( SR:8606251440 CR:JAGae17505 )
This product update contains minor enhancements required to
enable the HP-UX Strong Random Number Generator.
Resolution:
Enhancements added to set up the system for loading the
Strong Random Number Generator when this product is
configured.
PHKL_27054:
( SR:8606223938 CR:JAGad93033 )
This patch is a member of a set of patches needed to enable
version A.02.01.00 of the HP-UX Virtual Partitions product.
When the HP-UX Virtual Partitions product (VPARSBASE or
T1335AC) is installed, it will install the full set of
required patches for that product, including this patch.
If the HP-UX Virtual Partitions product is not installed,
this change will have no impact on your system.
Resolution:
Enhancements added to support CPU migration on cell based
systems like : Superdome, rp8400, rp7410.
PHKL_25166:
( SR:8606205090 CR:JAGad74266 )
This problem is caused by a defect in the hardware bus
arbitration logic. The arbitration logic favors the
sequential cache flush code over memory access requests,
such that outstanding I/O requests (e.g. FWSCSI) will time
out and cause an HPMC.
Resolution:
The sequential cache flush code was modified to periodically
provide a time slot for the I/O requests to finish.
PHKL_24557:
( SR:8606199585 CR:JAGad68772 )
This patch contains minor enhancements required to support
the HP-UX Virtual Partitions product.
Resolution:
Enhancements added to enable Purge Data TLB lock.
PHKL_25453:
( SR:8606186988 CR:JAGad56198 )
The graphics Block TLB entry is not set up on non-monarch
processors. When the X Server migrates off the monarch
processor, there is no valid TLB entry on the processor it
moves to. When the X Server tries to access an address that
should be covered by the Block TLB entry it gets a data page
fault and dumps core.
Resolution:
Moved the Graphics Block TLB initialization of non-monarch
processors from phase 1 to phase 2 of MP configuration so
that the entries get populated correctly on non-monarch
processors.
PHKL_24550:
( SR:8606244308 CR:JAGae10796 )
The Gang Scheduler only recognizes processor 0 even if there
are more processors in the system. This is because the Gang
Scheduler is initialized in the boot path before the other
processors are enabled.
Resolution:
The fix is to enable the other processors before the Gang
Scheduler is initialized, so that the Gang Scheduler will
recognize them.
Note that this fix is effective only in systems in which
neither PSETS nor VPARS nor both products are installed. A
fix for the Gang Scheduler problem in configurations
containing the PSETS and VPARS products is not planned at
this time.
( SR:8606200799 CR:JAGad69975 )
This patch contains minor enhancements required to support
the HP-UX Processor Sets product.
Resolution:
Enhancements added to provide initialization of Processor
Sets product in early system boot path.
( SR:8606199576 CR:JAGad68763 )
This patch contains minor enhancements required to support
the HP-UX Virtual Partitions product.
Resolution:
Enhancements added to support CPU migration.
PHKL_23609:
( SR:8606169455 CR:JAGad38730 )
Data and/or code translations are improperly disabled.
Resolution:
Set the OS tick interval to a longest possible value during
initializing non_monarch CPU's interval timer.
PHKL_30288:
( SR:8606337549 CR:JAGae98556 )
When a LWP thread is aborted by a pthread_cancel, a side
effect of is that the aborting thread may execute briefly
before being aborted completely. The thread may return to
user space and execute user program code during this brief
interval. Depending on what the user program does during
that period, unexpected, detrimental effects to the system
could result. For instance, the program could immediately
perform another system call where a semaphore or other
global resources could be acquired and cause the thread to
become unkillable, lead to a system deadlock/hang, etc.
Resolution:
The fix is to insert a call at the end of syscall to handle
the terminating process instead of letting it exit out of
syscall. That is, check the condition in the syscall path
where a thread returns to user space from the kernel to
ensure that an aborted thread does not return to user space.
PHKL_25842:
( SR:8606229034 CR:JAGad98088 )
The Operating System currently has no way to abort a
specific thread blocked interruptibly in a system call.
Resolution:
A new kernel internal interface (function) is introduced to
provide kernel subsystems the ability to abort a thread that
is currently blocked interruptibly in a system call.This
portion of the functionality clears flags associated with
the new routine.
Enhancement:
No (superseded patches contained enhancements)
PHKL_30606:
Hooks to setup the system for HP-UX Detect
and Strobe when this product is installed.
Round robin handling of interrupt EIRR bits.
PHKL_27766:
Enhancements added to set up the system for
loading the Strong Random Number Generator
when this product is configured.
