Date: Thu, 11 Jun 2020 10:53:59 -0700 (PDT) From: Palmer Dabbelt <palmer@...belt.com> To: Linus Torvalds <torvalds@...ux-foundation.org> CC: linux-riscv@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [GIT PULL] RISC-V Patches for the 5.8 Merge Window, Part 2 The following changes since commit 084623e468d535d98f883cc2ccf2c4fdf2108556: Merge tag 'modules-for-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux (2020-06-05 12:31:16 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git tags/riscv-for-linus-5.8-mw1 for you to fetch changes up to 01f76386b0ac0b1c1094456c8f43ea6085fc49d2: riscv: set the permission of vdso_data to read-only (2020-06-10 19:47:35 -0700) ---------------------------------------------------------------- RISC-V Patches for the 5.8 Merge Window, Part 2 * Select statements are now sorted alphanumerically. * Our first-level interrupts are now handled via a full irqchip driver. * CPU hotplug is fixed. * Our vDSO calls now use the common vDSO infrastructure. ---------------------------------------------------------------- Anup Patel (7): RISC-V: self-contained IPI handling routine RISC-V: Rename and move plic_find_hart_id() to arch directory irqchip: RISC-V per-HART local interrupt controller driver clocksource/drivers/timer-riscv: Use per-CPU timer interrupt RISC-V: Remove do_IRQ() function RISC-V: Force select RISCV_INTC for CONFIG_RISCV RISC-V: Don't mark init section as non-executable Palmer Dabbelt (1): RISC-V: Sort select statements alphanumerically Vincent Chen (2): riscv: use vDSO common flow to reduce the latency of the time-related functions riscv: set the permission of vdso_data to read-only Zong Li (1): riscv: fix build warning of missing prototypes arch/riscv/Kconfig | 74 +++++++++------- arch/riscv/include/asm/clocksource.h | 7 ++ arch/riscv/include/asm/irq.h | 5 -- arch/riscv/include/asm/processor.h | 13 +-- arch/riscv/include/asm/smp.h | 3 + arch/riscv/include/asm/vdso.h | 2 + arch/riscv/include/asm/vdso/clocksource.h | 8 ++ arch/riscv/include/asm/vdso/gettimeofday.h | 79 +++++++++++++++++ arch/riscv/include/asm/vdso/processor.h | 19 ++++ arch/riscv/include/asm/vdso/vsyscall.h | 27 ++++++ arch/riscv/kernel/cpu.c | 16 ++++ arch/riscv/kernel/entry.S | 4 +- arch/riscv/kernel/irq.c | 33 +------ arch/riscv/kernel/patch.c | 1 + arch/riscv/kernel/smp.c | 11 ++- arch/riscv/kernel/time.c | 9 ++ arch/riscv/kernel/traps.c | 2 - arch/riscv/kernel/vdso.c | 24 ++++- arch/riscv/kernel/vdso/Makefile | 12 ++- arch/riscv/kernel/vdso/clock_getres.S | 18 ---- arch/riscv/kernel/vdso/clock_gettime.S | 18 ---- arch/riscv/kernel/vdso/gettimeofday.S | 18 ---- arch/riscv/kernel/vdso/vdso.lds.S | 2 + arch/riscv/kernel/vdso/vgettimeofday.c | 25 ++++++ arch/riscv/mm/init.c | 11 --- drivers/clocksource/timer-riscv.c | 43 ++++++++- drivers/irqchip/Kconfig | 13 +++ drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-riscv-intc.c | 138 +++++++++++++++++++++++++++++ drivers/irqchip/irq-sifive-plic.c | 46 +++++----- include/linux/cpuhotplug.h | 1 + 31 files changed, 500 insertions(+), 183 deletions(-) create mode 100644 arch/riscv/include/asm/clocksource.h create mode 100644 arch/riscv/include/asm/vdso/clocksource.h create mode 100644 arch/riscv/include/asm/vdso/gettimeofday.h create mode 100644 arch/riscv/include/asm/vdso/processor.h create mode 100644 arch/riscv/include/asm/vdso/vsyscall.h delete mode 100644 arch/riscv/kernel/vdso/clock_getres.S delete mode 100644 arch/riscv/kernel/vdso/clock_gettime.S delete mode 100644 arch/riscv/kernel/vdso/gettimeofday.S create mode 100644 arch/riscv/kernel/vdso/vgettimeofday.c create mode 100644 drivers/irqchip/irq-riscv-intc.c
