2016-10-06MIPS: Print CM error reports upon bus errorsPaul Burton2-21/+0
If a bus error occurs on a system with a MIPS Coherence Manager (CM) then the CM may hold useful diagnostic information. Printing this out has so far been left up to boards, with the requirement that they register a board_be_handler function & call mips_cm_error_decode() from there. In order to avoid boards other than Malta needing to duplicate this code, call mips_cm_error_decode() automatically if the board registers no board_be_handler, and remove the Malta implementation of that. This patch results in no functional change, but removes a further piece of platform-specific code.

2016-10-06MIPS: Sanitise coherentio semanticsPaul Burton1-2/+2
The coherentio variable has previously been used as a boolean value, indicating whether the user specified that coherent I/O should be enabled or disabled. It failed to take into account the case where the user does not specify any preference, in which case it makes sense that we should default to coherent I/O if the hardware supports it (hw_coherentio is non-zero). Introduce an enum to clarify the 3 different values of coherentio & use it throughout the code, modifying plat_device_is_coherent() & r4k_cache_init() to take into account the default case.

2016-10-06MIPS: Malta: Use all available DDR by defaultPaul Burton1-6/+104
Malta boards can have more than 256MB DDR available, but we have previously only made use of up to 256MB (ie. the DDR accessible via kseg0) by default, without the user manually specifying mem= kernel parameters. This patch causes all available DDR, as reported by the bootloader via the ememsize or memsize environment variables or optionally on the command line, to be used when possible without the user needing to manually provide the memory ranges. Malta now has 2 subtly different memory maps which have to be taken into account when setting this up. The original memory map (referred to by the code as v1) has up to 2GB of DDR aliased in both the upper & lower halves of the 32 bit physical address space, with a 256MB I/O region obscuring 0x10000000-0x1fffffff only in the lower alias. The revised v2 memory map is flat with up to 4GB DDR starting from 0x0, and the I/O region obscures 256MB of DDR which becomes inacessible. The memory map in use is indicated by a register provided by the rocit2 system controller, which is checked in order to set up the kernels memory ranges accordingly.

2016-09-29MIPS: Malta: Fix IOCU disable switch read for MIPS64Paul Burton1-1/+7
Malta boards used with CPU emulators feature a switch to disable use of an IOCU. Software has to check this switch & ignore any present IOCU if the switch is closed. The read used to do this was unsafe for 64 bit kernels, as it simply casted the address 0xbf403000 to a pointer & dereferenced it. Whilst in a 32 bit kernel this would access kseg1, in a 64 bit kernel this attempts to access xuseg & results in an address error exception. Fix by accessing a correctly formed ckseg1 address generated using the CKSEG1ADDR macro. Whilst modifying this code, define the name of the register and the bit we care about within it, which indicates whether PCI DMA is routed to the IOCU or straight to DRAM. The code previously checked that bit 0 was also set, but the least significant 7 bits of the CONFIG_GEN0 register contain the value of the MReqInfo signal provided to the IOCU OCP bus, so singling out bit 0 makes little sense & that part of the check is dropped.

2016-08-04tree-wide: replace config_enabled() with IS_ENABLED()Masahiro Yamada3-4/+4
The use of config_enabled() against config options is ambiguous. In practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the author might have used it for the meaning of IS_ENABLED(). Using IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention clearer. This commit replaces config_enabled() with IS_ENABLED() where possible. This commit is only touching bool config options. I noticed two cases where config_enabled() is used against a tristate option: - config_enabled(CONFIG_HWMON) [ drivers/net/wireless/ath/ath10k/thermal.c ] - config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE) [ drivers/gpu/drm/gma500/opregion.c ] I did not touch them because they should be converted to IS_BUILTIN() in order to keep the logic, but I was not sure it was the authors' intention.

2016-05-13MIPS: malta-time: Take seconds into accountJames Hogan1-5/+27
When estimating the clock frequency based on the RTC, take seconds into account in case the Update In Progress (UIP) bit wasn't seen. This can happen in virtual machines (which may get pre-empted by the hypervisor at inopportune times) with QEMU emulating the RTC (and in fact not setting the UIP bit for very long), especially on slow hosts such as FPGA systems and hardware emulators. This results in several seconds actually having elapsed before seeing the UIP bit instead of just one second, and exaggerated timer frequencies. While updating the comments, they're also fixed to match the code in that the rising edge of the update flag is detected first, not the falling edge. The rising edge gives a more precise point to read the counters in a virtualised system than the falling edge, resulting in a more accurate frequency. It does however mean that we have to also wait for the falling edge before doing the read of the RTC seconds register, otherwise it seems to be possible in slow hardware emulation to stray into the interval when the RTC time is undefined during the update (at least 244uS after the rising edge of the update flag). This can result in both seconds values reading the same, and it wrapping to 60 seconds, vastly underestimating the frequency.

2016-02-09MIPS: Fix early CM probingPaul Burton1-8/+0
Commit c014d164f21d ("MIPS: Add platform callback before initializing the L2 cache") added a platform_early_l2_init function in order to allow platforms to probe for the CM before L2 initialisation is performed, so that CM GCRs are available to mips_sc_probe. That commit actually fails to do anything useful, since it checks mips_cm_revision to determine whether it should call mips_cm_probe but the result of mips_cm_revision will always be 0 until mips_cm_probe has been called. Thus the "early" mips_cm_probe call never occurs. Fix this & drop the useless weak platform_early_l2_init function by simply calling mips_cm_probe from setup_arch. For platforms that don't select CONFIG_MIPS_CM this will be a no-op, and for those that do it removes the requirement for them to call mips_cm_probe manually (although doing so isn't harmful for now).

2015-08-03MIPS: SMP: Don't increment irq_count multiple times for call function IPIsAlex Smith1-1/+1
The majority of SMP platforms handle their IPIs through do_IRQ() which calls irq_{enter/exit}(). When a call function IPI is received, smp_call_function_interrupt() is called which also calls irq_{enter,exit}(), meaning irq_count is raised twice. When tick broadcasting is used (which is implemented via a call function IPI), this incorrectly causes all CPU idle time on the core receiving broadcast ticks to be accounted as time spent servicing IRQs, as account_process_tick() will account as such if irq_count is greater than 1. This results in 100% CPU usage being reported on a core which receives its ticks via broadcast. This patch removes the SMP smp_call_function_interrupt() wrapper which calls irq_{enter,exit}(). Platforms which handle their IPIs through do_IRQ() now call generic_smp_call_function_interrupt() directly to avoid incrementing irq_count a second time. Platforms which don't (loongson, sgi-ip27, sibyte) call generic_smp_call_function_interrupt() wrapped in irq_{enter,exit}().

This corrupts the current time, can result in the RTC seconds being an invalid BCD (e.g. 0x1a..0x1f) for up to 6 seconds, as well as confusing YAMON for a while after reset, enough for it to report timeouts when attempting to load from TFTP (it actually uses the RTC in that code). Therefore only initialise the RTC to the extent that is necessary so that Linux avoids interfering with the bootloader setup, while also allowing it to estimate the CPU frequency without hanging, without a bootloader necessarily having done anything with the RTC (for example when the kernel is loaded via EJTAG). The divider control is configured for a 32KHZ reference clock if necessary, and the SET bit of the RTC_CONTROL register is cleared if necessary without changing any other bits (this bit will be set when coming out of reset if the battery has been disconnected).

2015-07-10MIPS: Malta: Make GIC FDC IRQ workaround Malta specificJames Hogan1-7/+13
Wider testing reveals that the Fast Debug Channel (FDC) interrupt is routed through the GIC just fine on Pistachio SoC, even though it contains interAptiv cores. Clearly the FDC interrupt routing problems previously observed on interAptiv and proAptiv cores are specific to the Malta FPGA bitstreams. Move the workaround for interAptiv and proAptiv out of gic_get_c0_fdc_int() in the GIC irqchip driver into Malta's get_c0_fdc_int() platform callback, to allow the Pistachio SoC to use the FDC interrupt.

2014-11-24irqchip: mips-gic: Support local interruptsAndrew Bresticker2-13/+6
The MIPS GIC supports 7 local interrupts, 2 of which are the GIC local watchdog and count/compare timer. The remainder are CPU interrupts which may optionally be re-routed through the GIC. GIC hardware IRQs 0-6 are now used for local interrupts while hardware IRQs 7+ are used for external (shared) interrupts. Note that the 5 CPU interrupts may not be re-routable through the GIC. In that case mapping will fail and the vectors reported in C0_IntCtl should be used instead. gic_get_c0_compare_int() and gic_get_c0_perfcount_int() will return the correct IRQ number to use for the C0 timer and perfcounter interrupts based on the routability of those interrupts through the GIC. A separate irq_chip, with callbacks that mask/unmask the local interrupt on all CPUs, is used for the C0 timer and performance counter interrupts since all other platforms do not use the percpu IRQ API for those interrupts. Malta, SEAD-3, and the GIC clockevent driver have been updated to use local interrupts and the R4K clockevent driver has been updated to poll for C0 timer interrupts through the GIC when the GIC is present.

Now that the GIC properly uses IRQ domains, kill off the per-platform routing tables that were used to make the GIC appear transparent. This includes: - removing the mapping tables and the support for applying them, - moving GIC IPI support to the GIC driver, - properly routing the i8259 through the GIC on Malta, and - updating IRQ assignments on SEAD-3 when the GIC is present. Platforms no longer will pass an interrupt mapping table to gic_init. Instead, they will pass the CPU interrupt vector (2 - 7) that they expect the GIC to route interrupts to. Note that in EIC mode this value is ignored and all GIC interrupts are routed to EIC vector 1.
