This code is stalled, with no one working on it anymore, and the main msm code is now going through the proper channels to get merged correctly. So remove it as it contains a number of kernel information leaks and it is doubtful if it even still builds anymore.

The "kgdb_connected" variable of debug_core just indicates whether or not kgdbts is connected to the debug_core. It does not completely prevent a script from trying invoke kgdbts again and possibly crashing the system (see Call Trace below). The configured variable in kgtbts can be used instead of kgdb_connected instead of kgdb_connected. The cleanup_kgdbts() can also be removed because there is no possible way to build kgdbts as a kernel module that you could unload with rmmod.

Since MIPS modules' address space differs from the core kernel space, to access the _mcount in the core kernel, the kernel functions in modules must use long call (-mlong-calls): load the _mcount address into one register and jump to the address stored by the register: c: 3c030000 lui v1,0x0 <--------> b label c: R_MIPS_HI16 _mcount c: R_MIPS_NONE *ABS* c: R_MIPS_NONE *ABS* 10: 64630000 daddiu v1,v1,0 10: R_MIPS_LO16 _mcount 10: R_MIPS_NONE *ABS* 10: R_MIPS_NONE *ABS* 14: 03e0082d move at,ra 18: 0060f809 jalr v1 label: In the old Perl version of recordmcount, we only need to record the position of the 1st R_MIPS_HI16 type of _mcount, and later, in ftrace_make_nop(), replace the instruction in this position by a "b label" and in ftrace_make_call(), replace it back. But, the default C version of recordmcount records all of the _mcount symbols, so, we must filter the 2nd _mcount like the Perl version of recordmcount does. The C version of recordmcount copes with the symbols before they are linked, So It doesn't know the type of the symbols and therefore can not filter the symbols as the Perl version of recordmcount does. But as we can see above, the 2nd _mcount symbols of the long call alawys follows the 1st _mcount symbol of the same long call, which means the offset from the 1st to the 2nd is fixed, it is 0x10-0xc = 4 here, 4 is the length of the 1st load instruciton, for MIPS has fixed length of instructions, this offset is always 4. And as we know, the _mcount is inserted into the entry of every kernel function, the offset between the other _mcount's is expected to be always bigger than 4. So, to filter the 2ns _mcount symbol of the long call, we can simply check the offset between two _mcount symbols, If it is 4, then, filter the 2nd _mcount symbol. To avoid touching too much code, an 'empty' function fn_is_fake_mcount() is added for all of the archs, and the specific archs can override it via chaning the function pointer: is_fake_mcount in do_file() with the e_machine. e.g. This patch adds MIPS_is_fake_mcount() to override the default fn_is_fake_mcount() pointed by is_fake_mcount. This fn_is_fake_mcount() checks if the _mcount symbol is fake, e.g. the 2nd _mcount symbol of the long call is fake, for there are 2 _mcount symbols mapped to one real mcount call, so, one of them is fake and must be filtered. This fn_is_fake_mcount() is called in sift_rel_mcount() after finding the _mcount symbols and before adding the _mcount symbol into mrelp, so, it can prevent the fake mcount symbol going into the last __mcount_loc table.

The TASK_SIZE macro should reflect the size of a user process virtual address space. Previously for 64-bit kernels, this was not the case. The immediate cause of pain was in hugetlbfs/inode.c:hugetlb_get_unmapped_area() where 32-bit processes trying to mmap a huge page would be served a page with an address outside of the 32-bit address range. But there are other uses of TASK_SIZE in the kernel as well that would like an accurate value. The new definition is nice because it now makes TASK_SIZE and TASK_SIZE_OF() yield the same value for any given process. For 32-bit kernels there should be no change, although I did factor out some code in asm/processor.h that became identical for the 32-bit and 64-bit cases. __UA_LIMIT is now set to ~((1 << SEGBITS) - 1) for 64-bit kernels. This should eliminate the possibility of getting a AddressErrorException in the kernel for addresses that pass the access_ok() test. With the patch applied, I can still run o32, n32 and n64 processes, and have an o32 shell fork/exec both n32 and n64 processes.

BMIPS processor cores are used in 50+ different chipsets spread across 5+ product lines. In many cases the chipsets do not share the same peripheral register layouts, the same register blocks, the same interrupt controllers, the same memory maps, or much of anything else. But, across radically different SoCs that share nothing more than the same BMIPS CPU, a few things are still mostly constant: SMP operations Access to performance counters DMA cache coherency quirks Cache and memory bus configuration So, it makes sense to treat each BMIPS processor type as a generic "building block," rather than tying it to a specific SoC. This makes it easier to support a large number of BMIPS-based chipsets without unnecessary duplication of code, and provides the infrastructure needed to support BMIPS-proprietary features.

This patch adds the mipsxx Perf-events support based on the skeleton. Generic hardware events and cache events are now fully implemented for the 24K/34K/74K/1004K cores. To support other cores in mipsxx (such as R10000/SB1), the generic hardware event tables and cache event tables need to be filled out. To support other CPUs which have different PMU than mipsxx, such as RM9000 and LOONGSON2, the additional files perf_event_$cpu.c need to be created. Raw event is an important part of Perf-events. It helps the user collect performance data for events that are not listed as the generic hardware events and cache events but ARE supported by the CPU's PMU. This patch also adds this feature for mipsxx 24K/34K/74K/1004K. For how to use it, please refer to processor core software user's manual and the comments for mipsxx_pmu_map_raw_event() for more details. Please note that this is a "precise" implementation, which means the kernel will check whether the requested raw events are supported by this CPU and which hardware counters can be assigned for them. To test the functionality of Perf-event, you may want to compile the tool "perf" for your MIPS platform. You can refer to the following URL: http://www.linux-mips.org/archives/linux-mips/2010-10/msg00126.html You also need to customize the CFLAGS and LDFLAGS in tools/perf/Makefile for your libs, includes, etc. In case you encounter the boot failure in SMVP kernel on multi-threading CPUs, you may take a look at: http://www.linux-mips.org/git?p=linux-mti.git;a=commitdiff;h=5460815027d802697b879644c74f0e8365254020Signed-off-by: NDeng-Cheng Zhu <dengcheng.zhu@gmail.com> To: linux-mips@linux-mips.org Cc: a.p.zijlstra@chello.nl Cc: paulus@samba.org Cc: mingo@elte.hu Cc: acme@redhat.com Cc: jamie.iles@picochip.com Cc: ddaney@caviumnetworks.com Cc: matt@console-pimps.org Patchwork: https://patchwork.linux-mips.org/patch/1689/Signed-off-by: NRalf Baechle <ralf@linux-mips.org> create mode 100644 arch/mips/kernel/perf_event_mipsxx.c

This patch provides the skeleton of the HW perf event support. To enable this feature, we can not choose the SMTC kernel; Oprofile should be disabled; kernel performance events be selected. Then we can enable it in Kernel type menu. Oprofile for MIPS platforms initializes irq at arch init time. Currently we do not change this logic to allow PMU reservation. If a platform has EIC, we can use the irq base and perf counter irq offset defines for the interrupt controller in specific init_hw_perf_events(). Based on this skeleton patch, the 3 different kinds of MIPS PMU, namely, mipsxx/loongson2/rm9000, can be supported by adding corresponding lower level C files at the bottom. The suggested names of these files are perf_event_mipsxx.c/perf_event_loongson2.c/perf_event_rm9000.c. So, for example, we can do this by adding "#include perf_event_mipsxx.c" at the bottom of perf_event.c. In addition, PMUs with 64bit counters are also considered in this patch.

The OCTEON II SOC has USB EHCI and OHCI controllers connected directly to the internal I/O bus. This patch adds the necessary 'glue' logic to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II. The OCTEON normally runs big-endian, and the ehci/ohci internal registers have host endianness, so we need to select USB_EHCI_BIG_ENDIAN_MMIO. The ehci and ohci blocks share a common clocking and PHY infrastructure. Initialization of the host controller and PHY clocks is common between the two and is factored out into the octeon2-common.c file.

Starting with cn63xx Octeon I/O blocks are clocked at a different rate than the CPU. Add a new function octeon_get_io_clock_rate() that yields the I/O clock rate. Also rearrange octeon_get_clock_rate() to get the value from the saved sysinfo structure.

The OCTEON II ISA extends the original OCTEON ISA, so give it its own __elf_platform string so optimized libraries can be selected in userspace.
