* [SPARC64]: Fix streaming buffer flushing on PCI and SBUS.David S. Miller2005-05-31
| | | | | | | | | | | | | Firstly, if the direction is TODEVICE, then dirty data in the streaming cache is impossible so we can elide the flush-flag synchronization in that case. Next, the context allocator is broken. It is highly likely that contexts get used multiple times for different dma mappings, which confuses the strbuf flushing code and makes it run inefficiently.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In IA64 kernel, sys_mmap calls do_mmap2 and do_mmap2 returns addr if len=0, which means the mmap sys call succeeds. Posix.1 says: The mmap() function shall fail if: [EINVAL] The value of len is zero. Here is a patch to fix it.

| * | [IA64] alternate perfmon handlerTony Luck2005-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Charles Spirakis Some linux customers want to optimize their applications on the latest hardware but are not yet willing to upgrade to the latest kernel. This patch provides a way to plug in an alternate, basic, and GPL'ed PMU subsystem to help with their monitoring needs or for specialty work. It can also be used in case of serious unexpected bugs in perfmon. Mutual exclusion between the two subsystems is guaranteed, hence no conflict can arise from both subsystem being present.

| * | [IA64-SGI] cpe interrupts are not being enabled.Russ Anderson2005-05-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | acpi_request_vector() is called in ia64_mca_init() to get the cpe_vector. The problem is that acpi_request_vector() looks in platform_intr_list[] to get the vector, but platform_intr_list[] is not initialized with a valid vector until later (in sn_setup()). Without a valid vector the code defaults to polling mode. This patch moves the call to acpi_request_vector() from ia64_mca_init() to ia64_mca_late_init(), which is after platform_intr_list[] is initialized.

| * | | [IA64] Avoid .spillpsp directive in handcoded assemblyDavid Mosberger-Tang2005-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some time ago, GAS was fixed to bring the .spillpsp directive in line with the Intel assembler manual (there was some disagreement as to whether or not there is a built-in 16-byte offset). Unfortunately, there are two places in the kernel where this directive is used in handwritten assembly files and those of course relied on the "buggy" behavior. As a result, when using a "fixed" assembler, the kernel picks up the UNaT bits from the wrong place (off by 16) and randomly sets NaT bits on the scratch registers. This can be noticed easily by looking at a coredump and finding various scratch registers with unexpected NaT values. The patch below fixes this by using the .spillsp directive instead, which works correctly no matter what assembler is in use.

This seem to be caused by either a too big latency caused by the cpufreq switch on wakeup from sleep or by an interrupt beeing lost due to the reset of the interrupt controller done during wakeup. This patch makes that code more robust by stopping PMU auto poll activity around cpufreq changes on machines that use the PMU for such changes (long latency switching involving a CPU hard reset and flush of all caches) and by removing the reset of the open pic interrupt controller on wakeup (that can cause the loss of an interrupt and Darwin doesn't do it, so it must not be necessary).

| * | | | | | [SPARC64]: Add boot option to force UltraSPARC-III P-Cache on.David S. Miller2005-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Older UltraSPARC-III chips have a P-Cache bug that makes us disable it by default at boot time. However, this does hurt performance substantially, particularly with memcpy(), and the bug is _incredibly_ obscure. I have never seen it triggered in practice, ever. So provide a "-P" boot option that forces the P-Cache on. It taints the kernel, so if it does trigger and cause some data corruption or OOPS, we will find out in the logs that this option was on when it happened. Signed-off-by: David S.

* | | | | | [PATCH] ppc64 iSeries: fix boot time settingStephen Rothwell2005-05-25

This patch works around that bug. This was most noticable when the root partition needed to be checked at every boot as the kernel thought it was some time in 1905 until user mode reset the time correctly.

* | | | | | [PATCH] ppc64: fix initialisation of gettimeofday calculationsStephen Rothwell2005-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On PPC64, we keep track of when we need to update jiffies (and the variables used to calculate the time of day) based on the time base. If the time base frequence is sufficiently high compared to the processor clock frequency, then it is possible for the time of day variables to be corrupted at the time of the first decrementer interrupt we take. This became obvious on a legacy iSeries where the time base frequency is the same as the processor clock. This one line patch fixes the initialisation so that the time of day variables and the indicator we use to tell when updates are due are better synchronised.
