| * MIPS: Alchemy: db1200: Improve PB1200 detection.Manuel Lauss2011-12-081-8/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PB1200 has the CPLD located at an address which on the DB1200 is RAM; reading the Board-ID sometimes results in a PB1200 being detected instead (especially during reboots after long uptimes). On the other hand, the address of the DB1200's CPLD is hosting Flash chips on the PB1200. Test for the DB1200 first and additionally do a quick write-test to the hexleds register to make sure we're writing to the CPLD.

So now this flag is a NOOP and can be removed.

| * | MIPS: Handle initmem in systems with kernel not in add_memory_region() memDavid Daney2011-12-074-14/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses a couple of related problems: 1) The kernel may reside in physical memory outside of the ranges set by plat_mem_setup(). If this is the case, init mem cannot be reused as it resides outside of the range of pages that the kernel memory allocators control. 2) initrd images might be loaded in physical memory outside of the ranges set by plat_mem_setup(). The memory likewise cannot be reused. The patch doesn't handle this specific case, but the infrastructure is useful for future patches that do. The crux of the problem is that there are memory regions that need be memory_present(), but that cannot be free_bootmem() at the time of arch_mem_init(). We create a new type of memory (BOOT_MEM_INIT_RAM) for use with add_memory_region(). Then arch_mem_init() adds the init mem with this type if the init mem is not already covered by existing ranges. When memory is being freed into the bootmem allocator, we skip the BOOT_MEM_INIT_RAM ranges so they are not clobbered, but we do signal them as memory_present(). This way when they are later freed, the necessary memory manager structures have initialized and the Sparse allocater is prevented from crashing. The Octeon specific code that handled this case is removed, because the new general purpose code handles the case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I am running SMP Linux 2.6.37-rc1 on BMIPS5000 (single core dual thread) and observe some abnormalities when doing system suspend/resume which I narrowed down to cpu hotplugging. The suspend brings the second thread processor down and then restarts it, after which I see memory corruption in userspace. I started digging and found out that problem occurs because while doing execve() the child process is getting the same ASID as the parent, which obviously corrupts parent's address space. Further digging showed that activate_mm() calls get_new_mmu_context() to get a new ASID, but at this time ASID field in entryHi is 1, and asid_cache(cpu) is 0x100 (it was just reset to ASID_FIRST_VERSION when the secondary TP was booting). So, get_new_mmu_context() increments the asid_cache(cpu) value to 0x101, and thus puts 0x01 into entryHi. The result - ASID field does not get changed as it was supposed to. My solution is very simple - do not reset asid_cache(cpu) on TP warm restart. Patchwork: https://patchwork.linux-mips.org/patch/1797/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| * MIPS: Kernel hangs occasionally during boot.Al Cooper2011-11-081-19/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kernel hangs occasionally during boot after "Calibrating delay loop..". This is caused by the c0_compare_int_usable() routine in cevt-r4k.c returning false which causes the system to disable the timer and hang later. The false return happens because the routine is using a series of four calls to irq_disable_hazard() as a delay while it waits for the timer changes to propagate to the cp0 cause register. On newer MIPS cores, like the 74K, the series of irq_disable_hazard() calls turn into ehb instructions and can take as little as a few clock ticks for all 4 instructions. This is not enough of a delay, so the routine thinks the timer is not working. This fix uses up to a max number of cycle counter ticks for the delay and uses back_to_back_c0_hazard() instead of irq_disable_hazard() to handle the hazard condition between cp0 writes and cp0 reads.
