2013-02-15ARC: [Review] Prevent incorrect syscall restartsVineet Gupta
Per Al Viro's "signals for dummies" https://lkml.org/lkml/2012/12/6/366 there are 3 golden rules for (not) restarting syscalls: " What we need to guarantee is * restarts do not happen on signals caught in interrupts or exceptions * restarts do not happen on signals caught in sigreturn() * restart should happen only once, even if we get through do_signal() many times." ARC Port already handled #1, this patch fixes #2 and #3. We use the additional state in pt_regs->orig_r8 to ckh if restarting has already been done once. Thanks to Al Viro for spotting this.

2013-02-15ARC: [Review] Preparing to fix incorrect syscall restarts due to signalsVineet Gupta
To avoid multiple syscall restarts (multiple signals) or no restart at all (sigreturn), we need just an extra bit of state "literally 1 bit" in struct pt_regs. orig_r8 is the best place to do this, however given the way it is encoded currently, we can't add anything simplistically. Current orig_r8: * syscalls -> 1 to NR_SYSCALLS * Exceptions -> NR_SYSCALLS + 1 * Break-point-> NR_SYSCALLS + 2 In new scheme it is a bit-field * lower short word contains the exact event type (and a new bit to represent restart semantics : if syscall was already / can't be restarted) * upper short word optionally containing the syscall num - needed by likes of tracehooks etc This patch only changes how orig_r8 is organised and nothing should change behaviourily.

2013-02-15ARC: Signal handlingVineet Gupta
Includes following fixes courtesy review by Al-Viro * Tracer poke to Callee-regs were lost Before going off into do_signal( ) we save the user-mode callee regs (as they are not saved by default as part of pt_regs). This is to make sure that that a Tracer (if tracing related signal) is able to do likes of PEEKUSR(callee-reg). However in return path we were simply discarding the user-mode callee regs, which would break a POKEUSR(callee-reg) from a tracer. * Issue related to multiple syscall restarts are addressed in next patch Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Al Viro <viro@ZenIV.linux.org.uk> Acked-by: Jonas Bonn <jonas@southpole.se>
2013-02-11ARC: Timers/counters/delay managementVineet Gupta
ARC700 includes 2 in-core 32bit timers TIMER0 and TIMER1. Both have exactly same capabilies. * programmable to count from TIMER<n>_CNT to TIMER<n>_LIMIT * for count 0 and LIMIT ~1, provides a free-running counter by auto-wrapping when limit is reached. * optionally interrupt when LIMIT is reached (oneshot event semantics) * rearming the interrupt provides periodic semantics * run at CPU clk ARC Linux uses TIMER0 for clockevent (periodic/oneshot) and TIMER1 for clocksource (free-running clock). Newer cores provide RTSC insn which gives a 64bit cpu clk snapshot hence is more apt for clocksource when available. SMP poses a bit of challenge for global timekeeping clocksource / sched_clock() backend: -TIMER1 based local clocks are out-of-sync hence can't be used (thus we default to jiffies based cs as well as sched_clock() one/both of which platform can override with it's specific hardware assist) -RTSC is only allowed in SMP if it's cross-core-sync (Kconfig glue ensures that) and thus usable for both requirements.

2013-02-11ARC: [optim] uaccess __{get,put}_user() optimisedVineet Gupta
Override asm-generic implementations. We basically gain on 2 fronts * checks for alignment no longer needed as we are only doing "unit" sized copies. (Careful observer could argue that While the kernel buffers are aligned, the user buffer in theory might not be - however in that case the user space is already broken when it tries to deref a hword/word straddling word boundary - so we are not making it any worse). * __copy_{to,from}_user( ) returns bytes that couldn't be copied, whereas get_user() returns 0 for success or -EFAULT (not size). Thus the code to do leftover bytes calculation can be avoided as well. The savings were significant: ~17k of code. bloat-o-meter vmlinux_uaccess_pre vmlinux_uaccess_post add/remove: 0/4 grow/shrink: 8/118 up/down: 1262/-18758 (-17496) ^^^^^^^^^ Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Acked-by: Arnd Bergmann <arnd@arndb.de>

2013-02-11ARC: irqflags - Interrupt enabling/disabling at in-core intcVineet Gupta
ARC700 has an in-core intc which provides 2 priorities (a.k.a.) "levels" of interrupts (per IRQ) hencforth referred to as L1/L2 interrupts. CPU flags register STATUS32 has Interrupt Enable bits per level (E1/E2) to globally enable (or disable) all IRQs at a level. Hence the implementation of arch_local_irq_{save,restore,enable,disable}( ) The STATUS32 reg can be r/w only using the AUX Interface of ARC, hence the use of LR/SR instructions. Further, E1/E2 bits in there can only be updated using the FLAG insn. The intc supports 32 interrupts - and per IRQ enabling is controlled by a bit in the AUX_IENABLE register, hence the implmentation of arch_{,un}mask_irq( ) routines.

2013-02-11ARC: Build system: Makefiles, Kconfig, Linker scriptVineet Gupta
Arnd in his review pointed out that arch Kconfig organisation has several deficiencies: * Build time entries for things which can be runtime extracted from DT (e.g. SDRAM size, core clk frequency..) * Not multi-platform-image-build friendly (choice .. endchoice constructs) * cpu variants support (750/770) is exclusive. The first 2 have been fixed in subsequent patches. Due to the nature of the 750 and 770, it is not possible to build for both together, w/o special runtime glue code which would hurt performance.
