| Series | ILP32 for ARM64 | expand |
Hi Catalin, According to latest plans figured out on Linaro Connect, ILP32 should be taken in 4.12 merge window. The window will be opened in less than a month, so I'd like to remind it to you, and ask if you have any questions/requests related to ILP32. Is it still realistic idea to take patches in 4.12? This is the rebase of ILP32 on latest linux-next: https://github.com/norov/linux/tree/ilp32-20170410 And glibc that I use for testing: https://github.com/norov/glibc/commits/dev9 Yury On Thu, Mar 02, 2017 at 12:49:08AM +0530, Yury Norov wrote: > This series enables aarch64 with ilp32 mode. > > As supporting work, it introduces ARCH_32BIT_OFF_T configuration > option that is enabled for existing 32-bit architectures but disabled > for new arches (so 64-bit off_t is is used by new userspace).

Sorry, I wasn't present at Linaro Connect, so definitely not involved in such decision. BTW, it would be nice to have Arnd's ack on patch 2 (32-bit ABI: introduce ARCH_32BIT_OFF_T config option). > The window will be opened in less than a month, so I'd like to remind > it to you, and ask if you have any questions/requests related to > ILP32. Is it still realistic idea to take patches in 4.12? 4.12 is not realistic and I wouldn't commit to a specific kernel version. Given the intrusiveness, such patches should sit in -next for at least 3-4 weeks (i.e. merged in the arch tree around -rc3). Anyway, I don't think the plan has changed since last time I stated it: https://lkml.org/lkml/2016/12/5/333 I haven't got the chance to test these patches yet, run benchmarks (step 4). Also, the latest benchmarks I've seen were mostly for user space while I'm more concerned with the user-kernel interface (https://marc.info/?l=linux-arm-kernel&m=148690490713310&w=2). Is there an up to date pre-built toolchain and a filesystem for ILP32? On the glibc testing side, have the regressions been identified/fixed? -- Catalin

He already acked it, but after some rebase I lost that line http://lists-archives.com/linux-kernel/28471253-32-bit-abi-introduce-arch_32bit_off_t-config-option.html Yury

I run LTP for testing the ABI and kernel, and there is no failures in ltplite scenario. With glibc testsuite, there's only 3 failures comparing to lp64. (Steve, fix me if something changed.) This is slides on ilp32 from Linaro Connect, hope you'll find it useful. https://docs.google.com/presentation/d/1TKZqgH0XJUgMMGkw2fJA3Lzr57slht1sGKYJVBJTNM4/edit?usp=sharing Yury

The failure is architecture-independent, it's related to the lack of a compat symbol and the difficulty of checking for that at the Makefile or test level. nptl/tst-stack4 is also a generic failure, I think. misc/tst-sync_file_range is probably a real failure related to argument passing. I think this system call was problematic on other architectures, too. Thanks, Florian (Sorry for the wide Cc: list despite the glibc content.)

That would be great, thanks. > misc/tst-sync_file_range is probably a real failure related to argument > passing. I think this system call was problematic on other architectures, > too. At first glance, it's pretty trivial, both on glibc and kernel side: GLIBC: int sync_file_range (int fd, __off64_t offset, __off64_t len, unsigned int flags) { #if defined (__NR_sync_file_range2) return SYSCALL_CANCEL (sync_file_range2, fd, flags, SYSCALL_LL64 (offset), SYSCALL_LL64 (len)); #elif defined (__NR_sync_file_range) return SYSCALL_CANCEL (sync_file_range, fd, __ALIGNMENT_ARG SYSCALL_LL64 (offset), SYSCALL_LL64 (len), flags); #endif } And kernel: ENTRY(compat_sys_sync_file_range2_wrapper) regs_to_64 x2, x2, x3 regs_to_64 x3, x4, x5 b sys_sync_file_range2 ENDPROC(compat_sys_sync_file_range2_wrapper) Anyway, I'll check everything and report here. Yury
This series enables aarch64 with ilp32 mode. As supporting work, it introduces ARCH_32BIT_OFF_T configuration option that is enabled for existing 32-bit architectures but disabled for new arches (so 64-bit off_t is is used by new userspace). Also it deprecates getrlimit and setrlimit syscalls prior to prlimit64. This version is based on linux-next from 2017-03-01. It works with glibc-2.25, and tested with LTP, glibc testsuite, trinity, lmbench, CPUSpec. Patches 1, 2, 3 and 8 are general, and may be applied separately. This is the rebase of v7 - no major changes has been made. Kernel and GLIBC trees: https://github.com/norov/linux/tree/ilp32-20170301 https://github.com/norov/glibc/tree/dev9 (GLIBC patches are managed by Steve Ellcey, so my tree is only for reference.)
