Release, which has been through 10 rounds of review on mailing list. We almost got the Acked-by/Reviewed-by of all patches except "Process management and Signal", but all've been tested. Here is the LTP-20180118 test report: ----------------------------------------------- Total Tests: 1298 Total Skipped Tests: 281 Total Failures: 10 Kernel Version: 4.19.0+ Machine Architecture: csky Hostname: buildroot ----------------------------------------------- This patchset adds architecture support to Linux for C-SKY's 32-bit embedded There are two ABI versions with several CPU cores in this patchset: ABIv1: 610 (16-bit instruction, 32-bit data path, VIPT Cache ...) ABIv2: 807 810 860 (16/32-bit variable length instruction, PIPT Cache, SMP ...) More information: http://en.c-sky.com The development repo: https://github.com/c-sky/csky-linux ABI Documentation: https://github.com/c-sky/csky-doc Here is the pre-built cross compiler for fast test from our CI: https://gitlab.com/c-sky/buildroot/-/jobs/101608095/artifacts/file/output/images/csky_toolchain_qemu_csky_ck807f_4.18_glibc_defconfig_482b221e52908be1c9b2ccb444255e1562bb7025.tar.xz We use buildroot as our CI-test enviornment. "LTP, Lmbench ..." will be tested for every commit. See here for more details: https://gitlab.com/c-sky/buildroot/pipelines We'll continouslly improve csky subsystem in future. Changes in v10: - Remove duplicated headers in asm/Kbuild and uapi/asm/Kbuild. - Change to (__NR_arch_specific_syscall + 1) in unistd.h. - Drop dword access for get_user_size patch. - Involve the interrupt controller drivers after got Reviewed-by. Changes in v9: - Remove unused code in smp.c and use per_cpu for ipi_data. - Fixup r15 register access in abiv1/alignment.c. - Improve the changelog comment in commit-msg. Changes in v8: - Pass make allmodconfig. - Implement abiv1 get_user_dword(). - Remove set_irq_mapping() used by driver in smp.c. Changes in v7: - Use checkpatch.pl to check all patches and fixup as possible. - Remove github.com/c-sky print in bootup. - Give a return in DMA_ATTR_NON_CONSISTENT in csky_dma_alloc_atomic(). - Remove the NSIGXXX in fpu.c and use force_sig_fault() in fpu.c. - Remove irq.h and add it in asm/Kbuild. - Use byteswap helpers in abiv1/bswapXi.c. - Fixup arch_sync_dma() only with one page problem. Changes in v6: - use asm-generic/bitops/atomic.h for all in asm/bitops.h - fix flush_cache_range and tlb_start_vma - fix compile error with include linux/bug.h in cmpxchg.h - improve the comment Changes in v5: - remove redundant smp_mb operations in spinlock.h - add commit message for dt-bindings docs - add CPUHP_AP_CSKY_TIMER_STARTING in hotplug.h for csky_mptimer - add COMPILE_TEST for timer-gx6605s Kconfig - seperate csky two interrupt controllers with 2 patches - add MAINTAINERS patch for csky - move IPI_IRQ into csky_mptimer, fixup irq_mapping problem - coding convension Changes in v4: - cleanup defconfig - use ksys_ in syscall.c - remove wrong comment in vdso.c - Use GENERIC_IRQ_MULTI_HANDLER - optimize the memset.c - fixup dts warnings - remove big-endian in byteorder.h Changes in v3: dc560f1 csky: change to EM_CSKY 252 for elf.h 2ac3ddf csky: remove gx6605s.dts af00b8c csky: add defconfig and qemu.dts 6c87efb csky: remove the deprecate name. f6dda39 csky: add dt-bindings doc. d9f02a8 csky: remove KERNEL_VERSION in upstream branch 7bd663c csky: Use kernel/dma/noncoherent.c 1544c09 csky: bugfix emmc hang up LINS-976 e963271 csky: cleanup include/asm/Kbuild cd267ba csky: remove CSKY_DEBUG_INFO 78950da csky: remove dcache invalid. 13fe51d csky: remove csum_ipv6_magic(), use generic one. a7372db csky: bugfix CK810 access twice error. 1bb7c69 csky: bugfix add gcc asm memory for barrier. 5ea3257 csky: add -msoft-float instead of -mfloat-abi=soft. 38b037d csky: bugfix losing cache flush range. ab5e8c4 csky: Add ticket-spinlock and qrwlock support. c9aaec5 csky: rename cskyksyms.c to libgcc_ksyms.c 28c5e48 csky: avoid the MB on failure: trylock f929c97 csky: bugfix idly4 may cause exception. 09dc496 csky: Use GENERIC_ASHLDI3/ASHRDI3 etc 6ecc99d csky: optimize smp boot code. 16f50df csky: asm/bug.h simple implement. 0ba532a csky: csky asm/atomic.h added. df66947 csky: asm/compat.h added |
