2007-11-26[MIPS] 64-bit Sibyte kernels need DMA32.Ralf Baechle1-0/+1
Sibyte SOCs only have 32-bit PCI. Due to the sparse use of the address space only the first 1GB of memory is mapped at physical addresses below 1GB. If a system has more than 1GB of memory 32-bit DMA will not be able to reach all of it. For now this patch is good enough to keep Sibyte users happy but it seems eventually something like swiotlb will be needed for Sibyte. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-11-26[MIPS] Only build r4k clocksource for systems that work ok with it.Ralf Baechle1-0/+11
In particular as-is it's not suited for multicore and mutiprocessors systems where there is on guarantee that the counter are synchronized or running from the same clock at all. This broke Sibyte and probably others since the "[MIPS] Handle R4000/R4400 mfc0 from count register." commit. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-11-26[MIPS] Handle R4000/R4400 mfc0 from count register.Ralf Baechle1-2/+3
The R4000 and R4400 have an errata where if the cp0 count register is read in the exact moment when it matches the compare register no interrupt will be generated. This bug may be triggered if the cp0 count register is being used as clocksource and the compare interrupt as clockevent. So a simple workaround is to avoid using the compare for both facilities on the affected CPUs. This is different from the workaround suggested in the old errata documents; at some opportunity probably the official version should be implemented and tested. Another thing to find out is which processor versions exactly are affected. I only have errata documents upto R4400 V3.0 available so for the moment the code treats all R4000 and R4400 as broken. This is potencially a problem for some machines that have no other decent clocksource available; this workaround will cause them to fall back to another clocksource, worst case the "jiffies" source.
2007-11-26[MIPS] Fix possible hang in LL/SC futex loops.Ralf Baechle1-3/+3
The LL / SC loops in __futex_atomic_op() have the usual fixups necessary for memory acccesses to userspace from kernel space installed: __asm__ __volatile__( " .set push \n" " .set noat \n" " .set mips3 \n" "1: ll %1, %4 # __futex_atomic_op \n" " .set mips0 \n" " " insn " \n" " .set mips3 \n" "2: sc $1, %2 \n" " beqz $1, 1b \n" __WEAK_LLSC_MB "3: \n" " .set pop \n" " .set mips0 \n" " .section .fixup,\"ax\" \n" "4: li %0, %6 \n" " j 2b \n" <----- " .previous \n" " .section __ex_table,\"a\" \n" " "__UA_ADDR "\t1b, 4b \n" " "__UA_ADDR "\t2b, 4b \n" " .previous \n" : "=r" (ret), "=&r" (oldval), "=R" (*uaddr) : "0" (0), "R" (*uaddr), "Jr" (oparg), "i" (-EFAULT) : "memory"); The branch at the end of the fixup code, it goes back to the SC instruction, no matter if the fault was first taken by the LL or SC instruction resulting in an endless loop which will only terminate if the address become valid again due to another thread setting up an accessible mapping and the CPU happens to execute the SC instruction successfully which due to the preceeding ERET instruction of the fault handler would only happen if UNPREDICTABLE instruction behaviour of the SC instruction without a preceeding LL happens to favor that outcome. But normally processes are nice, pass valid arguments and we were just getting away with this. Thanks to Kaz Kylheku <kaz@zeugmasystems.com> for providing the original report and a test case.

2007-11-26[MIPS] Fix context DSP context / TLS pointer switching bug for new threads.Ralf Baechle1-2/+6
A new born thread starts execution not in schedule but rather in ret_from_fork which results in it bypassing the part of the code to load a new context written in C which are the DSP context and the userlocal register which Linux uses for the TLS pointer. Frequently we were just getting away with this bug for a number of reasons: o Real world application scenarios are very unlikely to use clone or fork in blocks of DSP code. o Linux by default runs the child process right after the fork, so the child by luck will find all the right context in the DSP and userlocal registers. o So far the rdhwr instruction was emulated on all hardware so userlocal wasn't getting referenced at all and the emulation wasn't suffering from the issue since it gets it's value straight from the thread's thread_info. Fixed by moving the code to load the context from switch_to() to finish_arch_switch which will be called by newborn and old threads. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-11-16[MIPS] Fix shadow register support.Ralf Baechle1-0/+1
Shadow register support would not possibly have worked on multicore systems. The support code for it was also depending not on MIPS R2 but VSMP or SMTC kernels even though it makes perfect sense with UP kernels. SR sets are a scarce resource and the expected usage pattern is that users actually hardcode the register set numbers in their code. So fix the allocator by ditching it. Move the remaining CPU probe bits into the generic CPU probe. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-11-16[MIPS] Change get_cycles to always return 0.Ralf Baechle1-1/+1
This avoids us executing an mfc0 c0_count instruction on processors which don't have but also on certain R4000 and R4400 versions where reading from the count register just in the very moment when its value equals c0_compare will result in the timer interrupt getting lost. There is still a number of users of get_cycles remaining outside the arch code: crypto/tcrypt.c: start = get_cycles(); crypto/tcrypt.c: end = get_cycles(); crypto/tcrypt.c: start = get_cycles(); crypto/tcrypt.c: end = get_cycles(); crypto/tcrypt.c: start = get_cycles(); crypto/tcrypt.c: end = get_cycles(); drivers/char/hangcheck-timer.c: return get_cycles(); drivers/char/hangcheck-timer.c: printk("Hangcheck: Using get_cycles().\n"); drivers/char/random.c: sample.cycles = get_cycles(); drivers/input/joystick/analog.c:#define GET_TIME(x) do { x = get_cycles(); } include/linux/arcdevice.h: _x = get_cycles(); \ include/linux/arcdevice.h: _y = get_cycles(); \ mm/slub.c: if (!s->defrag_ratio || get_cycles() % 1024 > s->defrag_ratio) mm/slub.c: p += 64 + (get_cycles() & 0xff) * sizeof(void *); Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

The BCM148 has 4 cores but there are also just 4 generic timers available so use the ZBbus cycle counter instead of it. In addition the ZBbus counter also offers a much higher resolution and 64-bit counting so I'm considering a later complete conversion to it once I figure out if all members of the Sibyte SOC family support it - the docs seem to agree but the headers files seem to disagree ...

Next sg entry is located at sg + 1. - Bit 0 set: this is a chain entry, the next real entry is at ->page_link with the two low bits masked off. - Bit 1 set: this is the final entry in the sg entry. sg_next() will return NULL when passed such an entry.
