bbc448c541ed90d52f9ec22f17394304e3bf170e - mips: select CONFIG_WEAK_REORDERING_BEYOND_LLSC from CONFIG_EYEQ

Fri, 28 Aug 2026 16:07:33 +0200

mips: select CONFIG_WEAK_REORDERING_BEYOND_LLSC from CONFIG_EYEQOn I6500 CPU cores, lld and scd give no ordering guarantees (same as allother instructions). To respect the assumption that arch_cmpxchg() isfully ordered, we must inject sync instructions above and below ourlld/scd loops using the already in place WEAK_REORDERING_BEYOND_LLSCinfrastructure.Otherwise, bad things can happen:[ 34.054496] CPU 3 Unable to handle kernel paging request at virtual address 0000000000000000, epc == a80000080838e01c, ra == a80000080838dfc4[ 34.054559] Oops[#1]:[ 34.069561] CPU: 3 UID: 0 PID: 170 Comm: pipe_race Not tainted 7.2.0-rc6-01553-gb73c35220968-dirty #103 VOLUNTARY[ 34.079932] Hardware name: Mobile EyeQ5 MP5 Evaluation board[ 34.085592] $ 0 : 0000000000000000 0000000000000001 0000000000000000 0000000000000000[ 34.093616] $ 4 : a800000808ee2618 000000000b7a879d 0000000000001000 0000000000000000[ 34.101638] $ 8 : 0000000000e3f2c9 0000000000000000 a800000808a2a9f8 0000000000000000[ 34.109660] $12 : a8000008139ffcd8 ffffffff84080018 a80000080837fae0 7878787878787878[ 34.117682] $16 : a800000807e82940 0000000000001000 0000000000000000 0000000000000000[ 34.125704] $20 : a800000802920e00 a8000008139ffdf8 a800000802649400 0000000000e3f2c9[ 34.133726] $24 : 0000000000000006 00000001200406e0[ 34.141783] $28 : a8000008139fc000 a8000008139ffd10 0000000000e3f2c8 a80000080838dfc4[ 34.149837] epc : a80000080838e01c anon_pipe_read+0xd4/0x428[ 34.155697] ra : a80000080838dfc4 anon_pipe_read+0x7c/0x428[ 34.161549] Status: 140000e3 KX SX UX KERNEL EXL IE[ 34.166551] Cause : 40800408 (ExcCode 02)[ 34.170574] BadVA : 0000000000000000[ 34.174161] PrId : 0001b028 (MIPS I6500)[ 34.178183] Process pipe_race (pid: 170, threadinfo=000000005ca35720, task=00000000e1013890, tls=000000014ebbb780)[ 34.188568] Stack : a800000802649400 0000000000000000 0000000000000000 a8000008139ffdd0[ 34.196623] 0000000000000fba a800000808ee0000 0000000000000001 a8000008130c3e80[ 34.204676] a8000008080d1280 a8000008139ffd58 a8000008139ffd58 1dbd2b22ea1dd500[ 34.212729] a800000802649400 a800000808ee0000 ffffffffffffffea 0000000000000001[ 34.220783] 0000000000001000 0000000000000000 00000001200ae518 ffffffffffffffff[ 34.228836] 000000fffbe0e530 a80000080837edf4 000000fffbe0e530 0000000000000000[ 34.236890] 0000000000000000 0000000000000000 000000014ebb55a0 0000000000001000[ 34.244943] 0000000000000001 a800000802649400 0000000000000000 0000000000000000[ 34.252996] 0000000000000000 0000400400000000 0000000000000000 1dbd2b22ea1dd500[ 34.261049] 00000000140000e3 a800000802649400 a800000802649400 a800000808ee0000[ 34.269103] ...[ 34.271568] Call Trace:[ 34.274026] [] anon_pipe_read+0xd4/0x428[ 34.279533] [] vfs_read+0x25c/0x318[ 34.284607] [] ksys_read+0x104/0x138[ 34.289763] [] syscall_common+0x44/0x68[ 34.295187][ 34.296689] Code: f84000cf 02209825 de020010 d8400004 02002825 0040f809 02802025 f84000c3[ 34.306504][ 34.308099] ---[ end trace 0000000000000000 ]---My initial reproducer was the xdp-tools test suite.

Sincearch/mips/mobileye/Kconfig is sourced from arch/mips/Kconfig, bothdefinitions are parsed and the symbol ends up with two prompts.The symbol was first introduced in commit 101bd58fde10 ("MIPS: Addsupport for Mobileye EyeQ5") directly inarch/mips/Kconfig. Three months later, commit fbe0fae601b7 ("MIPS:mobileye: Add EyeQ6H support") created thearch/mips/mobileye/Kconfig sub-file to organize the growing Mobileyeplatform code and added the MACH_EYEQ5/MACH_EYEQ6H choice along witha copy of FIT_IMAGE_FDT_EPM5. However, the original definition inarch/mips/Kconfig was not removed at that time, leaving a duplicate.Remove the definition from arch/mips/Kconfig, keeping the one inarch/mips/mobileye/Kconfig where it belongs alongside the relatedMACH_EYEQ5 machine type definition that it depends on.Assisted-by: Claude:claude-opus-4-6 kconfiglintSigned-off-by: Sasha Levin Signed-off-by: Thomas Bogendoerfer List of files: /linux/arch/mips/Kconfig

Fri, 09 Jan 2026 11:08:49 +0100

MIPS: Implement ARCH_HAS_CC_CAN_LINKThe generic CC_CAN_LINK detection does not handle different byte ordersor ABIs. This may lead to userprogs which are not actually runnable onthe target kernel.Use architecture-specific logic supporting byte orders instead.Modern 64-bit toolchains default to a n32 libc, which are notsupported by all kernel configurations, as MIPS32_N32 is optional.On 64-bit, test for a n32 ABI libc first and fall back to o64 ando32 if necessary.Link: https://lore.kernel.org/lkml/20260105100507-14db55e3-aa71-48bf-a6ac-33b186bd082f@linutronix.de/Signed-off-by: Thomas Weißschuh Signed-off-by: Thomas Bogendoerfer List of files: /linux/arch/mips/Kconfig

Tue, 27 Jan 2026 13:12:57 +0100

mips: mm: enable MMU_GATHER_RCU_TABLE_FREEOn a 64-bit system, madvise(MADV_DONTNEED) may cause a large number ofempty PTE page table pages (such as 100GB+). To resolve this problem,first enable MMU_GATHER_RCU_TABLE_FREE to prepare for enabling thePT_RECLAIM feature, which resolves this problem.Link: https://lkml.kernel.org/r/0d17f00a724f77aaca2da7c847acd490c3a47571.1769515122.git.zhengqi.arch@bytedance.comSigned-off-by: Qi Zheng Cc: Thomas Bogendoerfer Cc: Andreas Larsson Cc: "Aneesh Kumar K.V" Cc: Anton Ivanov Cc: Borislav Petkov Cc: Dave Hansen Cc: David Hildenbrand (Red Hat) Cc: Dev Jain Cc: Helge Deller Cc: "H.
