* [PARISC] Allow nested interruptsJames Bottomley2006-10-04
| | | | | | | | | | | | Our prior mode of operation didn't allow nested interrupts because it makes the interrupt code much simpler. However, nested interrupts are better for latency. This code uses the EIEM register to simulate level interrupts and thus achieve nesting.

* [PARISC] Further updates to timer_interrupt()Grant Grundler2006-10-04
| | | | | | | | | | | | | This version (relative to the current tree): o eliminates "while (ticks_elapsed)" loop. It's not needed. o drop "ticks_elapsed" completely from timer_interrupt(). o Estimates elapsed cycles (based on HZ) to see which kind of math we want to use to calculate "cycles_remainder". o Fixes a bug where we would loose a tick if we decided we wanted to skip one interrupt.

* [PARISC] Rewrite timer_interrupt() and gettimeoffset() using "unsigned" math.Grant Grundler2006-10-04
| | | | | | | | | | It's just a bit easier to follow and timer code is complex enough. So far, only tested on A500-5x (64-bit SMP), ie: gettimeoffset() code hasn't been tested at all. Signed-off-by: Grant Grundler <grundler@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
* [PARISC] Add new function to start local Interval Timer, start_cpu_itimer()Grant Grundler2006-10-04
| | | | | | | | | | | | | | I couldn't find where the itimer was getting started for slave CPUs. CPU 0 (master) itimer was started in time_init() (arch/parisc/kernel/time.c). start_cpu_itimer() code was striped from time_init(). Slaves now start their itimer in smp_cpu_init(). This is a first step towards making gettimeoffset() work for SMP. Next step will be to determine the CR16 (cycle counter) offsets for each CPU relative to the master (CPU 0).

* [PARISC] parisc specific kmap API implementation for pa8800James Bottomley2006-10-04
| | | | | | | | | | | | | | | | This patch fixes the pa8800 at a gross level (there are still other subtle incoherency issues which can still cause crashes and HPMCs). What it does is try to force eject inequivalent aliases before they become visible to the L2 cache (which is where we get the incoherence problems). A new function (parisc_requires_coherency) is introduced in asm/processor.h to identify the pa8x00 processors (8800 and 8900) which have the issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was obesrved that at least one older PCI card predating the requirement for the TRDY signal to respond within 16 clock ticks actually does not meet this rule nor even the power-on defaults of the PCI bridges found in development systems built around the Broadcom SiByte SOCs. Here is a patch that bumps up the timeout to the highest finite value supported by these chips, which is 255 clock ticks. The bridges affected are the SiByte SOC itself and the SP1011. This change does not effectively affect systems only having PCI option cards installed that meet the TRDY requirement of the current PCI spec. The rule was introduced with PCI 2.1, so any older card may make the system affected. If this is the case, performance of the system will suffer in return for the card working at all. If this is a concern, then the solution is not to use such cards. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> ---

* x86: Fix booting with "no387 nofxsr"Linus Torvalds2006-10-03
| | | | | | | | | | | | | | | | | | | | | | Jesper Juhl reported that testing the software math-emulation by forcing "no387" doesn't work on modern CPU's. The reason was two-fold: - you also need to pass in "nofxsr" to make sure that we not only don't touch the old i387 legacy hardware, it also needs to disable the modern XMM/FXSR sequences - "nofxsr" didn't actually clear the capability bits immediately, leaving the early boot sequence still using FXSR until we got to the identify_cpu() stage. This fixes the "nofxsr" flag to take effect immediately on the boot CPU.

This is useful on production hardware such as the Zaurus cxx00 models where the valid modes are known in advance and any other modes could result in hardware damage. Following this, add support for the cxx00 QVGA mode. Mode information is passed to the lcd_power call to allowing the panel drivers to configure the display hardware accordingly (corgi_lcd already contains the functionality for the cxx00 panel).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently have a hardcoded 4 megabyte uncompressed kernel image size limit, which is easily exceeded by, for example, enabling some of the various kernel debugging options. When setting up the initial page tables (which is where this 4M limit is hardcoded), it's actually relatively easy to find out the true size of the uncompressed kernel image and create enough page table entries for things to fit, so this patch makes it so. In the decompressor, we also need to know the size of the uncompressed kernel image, to figure out whether there is any chance that uncompressing the kernel might overwrite the compressed kernel image stored elsewhere in memory. We don't have that info at this boot stage, though, so we approximate the size of the uncompressed kernel by taking the compressed kernel image size and allowing for a maximum 4x expansion.
