LoongArch: Add kdump support
This patch adds support for kdump. In kdump case the normal kernel will reserve a region for the crash kernel and jump there on panic. Arch-specific functions are added to allow for implementing a crash dump file interface, /proc/vmcore, which can be viewed as a ELF file. A user-space tool, such as kexec-tools, is responsible for allocating a separate region for the core's ELF header within the crash kdump kernel memory and filling it in when executing kexec_load(). Then, its location will be advertised to the crash dump kernel via a command line argument "elfcorehdr=", and the crash dump kernel will preserve this region for later use with arch_reserve_vmcore() at boot time. At the same time, the crash kdump kernel is also limited within the "crashkernel" area via a command line argument "mem=", so as not to destroy the original kernel dump data. In the crash dump kernel environment, /proc/vmcore is used to access the primary kernel's memory with copy_oldmem_page(). I tested kdump on LoongArch machines (Loongson-3A5000) and it works as expected (suggested crashkernel parameter is "crashkernel=512M@2560M"), you may test it by triggering a crash through /proc/sysrq-trigger: $ sudo kexec -p /boot/vmlinux-kdump --reuse-cmdline --append="nr_cpus=1" # echo c > /proc/sysrq-trigger Signed-off-by: Youling Tang <tangyouling@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> |

Kexec supports loading vmlinux.elf in ELF format and vmlinux.efi in PE format. I tested kexec on LoongArch machines (Loongson-3A5000) and it works as expected: $ sudo kexec -l /boot/vmlinux.efi --reuse-cmdline $ sudo kexec -e Signed-off-by: Youling Tang <tangyouling@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn> |

LoongArch: Use generic BUG() handler
Inspired by commit 9fb7410f955("arm64/BUG: Use BRK instruction for
generic BUG traps"), do similar for LoongArch to use generic BUG()
handler.
This patch uses the BREAK software breakpoint instruction to generate
a trap instead, similarly to most other arches, with the generic BUG
code generating the dmesg boilerplate.
This allows bug metadata to be moved to a separate table and reduces
the amount of inline code at BUG() and WARN() sites. This also avoids
clobbering any registers before they can be dumped.
To mitigate the size of the bug table further, this patch makes use of
the existing infrastructure for encoding addresses within the bug table
as 32-bit relative pointers instead of absolute pointers.
(Note: this limits the max kernel size to 2GB.)

LoongArch: Use TLB for ioremap()
We can support more cache attributes (e.g., CC, SUC and WUC) and page protection when we use TLB for ioremap(). The implementation is based on GENERIC_IOREMAP. The existing simple ioremap() implementation has better performance so we keep it and introduce ARCH_IOREMAP to control the selection. We move pagetable_init() earlier to make early ioremap() works, and we modify the PCI ecam mapping because the TLB-based version of ioremap() will actually take the size into account.

LoongArch: mm: Refactor TLB exception handlers
This patch simplifies TLB load, store and modify exception handlers:
1. Reduce instructions, such as alu/csr and memory access;
2. Execute tlb search instruction only in the fast path;
3. Return directly from the fast path for both normal and huge pages;
4. Re-tab the assembly for better vertical alignment.
And fixes the concurrent modification issue of fast path for huge pages.
This issue will occur in the following steps:
CPU-1 (In TLB exception) CPU-2 (In THP splitting)
1: Load PMD entry (HUGE=1)
2: Goto huge path
3: Store PMD entry (HUGE=0)
4: Reload PMD entry (HUGE=0)
5: Fill TLB entry (PA is incorrect)
This patch also slightly improves the TLB processing performance:
* Normal pages: 2.15%, Huge pages: 1.70%.

#include <stdlib.h>
#include <unistd.h>

LoongArch: Support R_LARCH_GOT_PC_{LO12,HI20} in modules
GCC >= 13 and GNU assembler >= 2.40 use these relocations to address external symbols, so we need to add them. Let the module loader emit GOT entries for data symbols so we would be able to handle GOT relocations. The GOT entry is just the data's symbol address. In module.lds, emit a stub .got section for a section header entry. The actual content of the section entry will be filled at runtime by module_ frob_arch_sections().

LoongArch: Adjust symbol addressing for AS_HAS_EXPLICIT_RELOCS
If explicit relocation hints are used by the toolchain, -Wa,-mla-*
options will be useless for the C code. So only use them for the
!CONFIG_AS_HAS_EXPLICIT_RELOCS case.
Replace "la" with "la.pcrel" in head.S to keep the semantic consistent
with new and old toolchains for the low level startup code.
For per-CPU variables, the "address" of the symbol is actually an offset
from $r21. The value is near the loading address of main kernel image,
but far from the loading address of modules. So we use model("extreme")
attibute to tell the compiler that a PC-relative addressing with 32-bit
offset is not sufficient for local per-CPU variables.
The behavior with different assemblers and compilers are summarized in
the following table:
AS has CC has
explicit relocs explicit relocs * Behavior
==============================================================
No No Use la.* macros.
No change from Linux 6.0.
--------------------------------------------------------------
No Yes Disable explicit relocs.
No change from Linux 6.0.
--------------------------------------------------------------
Yes No Not supported.
--------------------------------------------------------------
Yes Yes Enable explicit relocs.
No -Wa,-mla* options used.
==============================================================
*: We assume CC must have model attribute if it has explicit relocs.
Both features are added in GCC 13 development cycle, so any GCC
release >= 13 should be OK. Using early GCC 13 development snapshots
may produce modules with unsupported relocations.

LoongArch: Add Kconfig option AS_HAS_EXPLICIT_RELOCS
GNU as >= 2.40 and GCC >= 13 will support using explicit relocation hints in the assembly code, instead of la.* macros. The usage of explicit relocation hints can improve code generation so it's enabled by default by GCC >= 13. Introduce a Kconfig option AS_HAS_EXPLICIT_RELOCS as the switch for "use explicit relocation hints or not".

LoongArch: Flush TLB earlier at initialization
Move local_flush_tlb_all() earlier (just after setup_ptwalker() and before page allocation). This can avoid stale TLB entries misguiding the later page allocation. Without this patch the second kernel of kexec/kdump fails to boot SMP. BTW, move output_pgtable_bits_defines() into tlb_init() since it has nothing to do with tlb handler setup.

LoongArch: Do not create sysfs control file for io master CPUs
Now io master CPUs are not hotpluggable on LoongArch, but in the current
code only /sys/devices/system/cpu/cpu0/online is not created. Let us set
the hotpluggable field of all the io master CPUs as 0, then prevent to
create sysfs control file for all the io master CPUs which confuses some
user space tools. This is similar with commit

irqchip: IMX_MU_MSI should depend on ARCH_MXC
The Freescale/NXP i.MX Messaging Unit is only present on Freescale/NXP
i.MX SoCs. Hence add a dependency on ARCH_MXC, to prevent asking the
user about this driver when configuring a kernel without Freescale/NXP
i.MX SoC family support.
While at it, expand "MU" to "Messaging Unit" in the help text.

^C[ perf record: Woken up 227 times to write data ]
[ perf record: Captured and wrote 58.760 MB perf.data (836978 samples) ]
$ sudo perf mem report -F mem,sample,snoop

- "perf lock" improvements:
- Add -E/--entries option to limit the number of entries to display, say to ask for
just the top 5 contended locks.
- Add -q/--quiet option to suppress header and debug messages.
- Add a 'perf test' kernel lock contention entry to test 'perf lock'.
- "perf lock contention" improvements:
- Ask BPF's bpf_get_stackid() to skip some callchain entries.
The ones closer to the tooling are bpf related and not that interesting, the
ones calling the locking function are the ones we're interested in, example
of a full, unskipped callstack:
- Allow changing the callstack depth and number of entries to skip.

0xffffffffbb841015 tick_do_update_jiffies64+0x25
0xffffffffbb8409ee tick_irq_enter+0x9e
- Show full callstack in verbose mode (-v option), sometimes this is desirable
instead of showing just one callstack entry.
- Allow multiple time ranges in 'perf record --delay' to help in reducing the
amount of data collected from hardware tracing (Intel PT, etc) when there is
a rough idea of periods of time where events of interest take time.
- Add Intel PT to record only decoder debug messages when error happens.
- Improve layout of Intel PT man page.
- Add new branch types: alignment, data and inst faults and arch specific ones,
such as fiq, debug_halt, debug_exit, debug_inst and debug_data on arm64.
Kernel enablement went thru the tip tree.
- Fix 'perf probe' error log check in 'perf test' when no debuginfo is
available.
- Fix 'perf stat' aggregation mode logic, it should be looking at the CPU
not at the core number.
- Fix flags parsing in 'perf trace' filters.
- Introduce compact encoding of CPU range encoding on perf.data, to avoid
having a bitmap with all the CPUs.
- Improvements to the 'perf stat' metrics, including adding "core_wide", and
computing "smt" from the CPU topology.
- Add support to the new PERF_FORMAT_LOST perf_event_attr.read_format, that allows
tooling to ask for the precise number of lost samples for a given event.
- Add 'addr' sort key to see just the address of sampled instructions:
$ perf record -o- true | perf report -i- -s addr
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.000 MB - ]

perf annotate: Toggle full address <-> offset display
- Add 'f' hotkey to the 'perf annotate' TUI interface when in 'disassembler output'
mode ('o' hotkey) to toggle showing full virtual address or just the offset.
- Cache DSO build-ids when synthesizing PERF_RECORD_MMAP records for pre-existing threads,
at the start of a 'perf record' session, speeding up that record startup phase.
- Add a command line option to specify build ids in 'perf inject'.
- Update JSON event files for the Intel alderlake, broadwell, broadwellde,
broadwellx, cascadelakex, haswell, haswellx, icelake, icelakex, ivybridge,
ivytown, jaketown, sandybridge, sapphirerapids, skylake, skylakex, and
tigerlake processors.
- Update vendor JSON event files for the ARM Neoverse V1 and E1 platforms.
- Add a 'perf test' entry for 'perf mem' where a struct has false sharing and
this gets detected in the 'perf mem' output, tested with Intel, AMD and ARM64
systems.
- Add a 'perf test' entry to test the resolution of java symbols, where an
output like this is expected:
8.18% jshell jitted-50116-29.so [.] Interpreter
0.75% Thread-1 jitted-83602-1670.so [.] jdk.internal.jimage.BasicImageReader.getString(int)
- Add tests for the ARM64 CoreSight hardware tracing feature, with specially
crafted pureloop, memcpy, thread loop and unroll tread that then gets
traced and the output compared with expected output.
Documentation explaining it is also included.
- Add per thread Intel PT 'perf test' entry to check that PERF_RECORD_TEXT_POKE events
are recorded per CPU, resulting in a mixture of per thread and per CPU events and mmaps,
verify that this gets all recorded correctly.
- Introduce pthread mutex wrappers to allow for building with clang's
-Wthread-safety, i.e. using the "guarded_by" "pt_guarded_by" "lockable",
"exclusive_lock_function", "exclusive_trylock_function",
"exclusive_locks_required", and "no_thread_safety_analysis" compiler function
attributes.
- Fix empty version number when building outside of a git repo.
- Improve feature detection display when multiple versions of a feature are present, such
as for binutils libbfd, that has a mix of possible ways to detect according to the
Linux distribution.
Previously in some cases we had:
Auto-detecting system features
<SNIP>
... libbfd: [ on ]
... libbfd-liberty: [ on ]
... libbfd-liberty-z: [ on ]
<SNIP>
Now for this case we show just the main feature:
Auto-detecting system features
<SNIP>
... libbfd: [ on ]
<SNIP>
- Remove some unused structs, variables, macros, function prototypes and
includes from various places.

0.75% Thread-1 jitted-83602-1670.so [.] jdk.internal.jimage.BasicImageReader.getString(int)
- Add tests for the ARM64 CoreSight hardware tracing feature, with
specially crafted pureloop, memcpy, thread loop and unroll tread that
then gets traced and the output compared with expected output.
Documentation explaining it is also included.
- Add per thread Intel PT 'perf test' entry to check that
PERF_RECORD_TEXT_POKE events are recorded per CPU, resulting in a
mixture of per thread and per CPU events and mmaps, verify that this
gets all recorded correctly.
- Introduce pthread mutex wrappers to allow for building with clang's
-Wthread-safety, i.e. using the "guarded_by" "pt_guarded_by"
"lockable", "exclusive_lock_function", "exclusive_trylock_function",
"exclusive_locks_required", and "no_thread_safety_analysis" compiler
function attributes.
- Fix empty version number when building outside of a git repo.
- Improve feature detection display when multiple versions of a feature
are present, such as for binutils libbfd, that has a mix of possible
ways to detect according to the Linux distribution.
Previously in some cases we had:
Auto-detecting system features
<SNIP>
... libbfd: [ on ]
... libbfd-liberty: [ on ]
... libbfd-liberty-z: [ on ]
<SNIP>
Now for this case we show just the main feature:
Auto-detecting system features
<SNIP>
... libbfd: [ on ]
<SNIP>
- Remove some unused structs, variables, macros, function prototypes
and includes from various places.

Pull pci updates from Bjorn Helgaas:
"Resource management:
- Distribute spare resources to unconfigured hotplug bridges at
boot-time (not just when hot-adding such a bridge), which makes
hot-adding devices to docks work better.
- Revert to a BAR assignment inherited from firmware only when the
address is actually reachable via any upstream bridges, which fixes
some cases where firmware doesn't configure all devices.
- Add a sysfs interface to resize BARs so this can be done before
assigning devices to a VM through VFIO.
Power management:
- Disable Precision Time Management for all devices on suspend to
enable lower-power PM state. We previously did this just for Root
Ports, which isn't enough because downstream devices can still
generate PTM messages, which cause errors if it's disabled in the
Root Port.
- Save and restore the ASPM L1 PM Substates configuration for
suspend/ resume. Previously this configuration was lost, so L1.x
states likely stopped working after resume.
- Check whether the L1 PM Substates Capability exists. If it didn't
exist, we previously read junk and tried to configure L1 Substates
based on that.
- Fix the LTR_L1.2_THRESHOLD computation, which previously set a
threshold for entering L1.2 that was too low in some cases.
- Reduce the delay after transitions to or from D3cold by using
usleep_range() rather than msleep(), which often slept for ~19ms
instead of the 10ms normally required. The spec says 10ms is
enough, but it's possible we could trip over devices that need a
little more.
Error handling:
- Work around a BIOS bug that caused Intel Root Ports to advertise a
Root Port Programmed I/O (RP PIO) log size of zero, which caused
annoying warnings and prevented the kernel from dumping log
registers for DPC errors.
Qualcomm PCIe controller driver:
- Add support for SC8280XP and SA8540P host controllers and SM8450
endpoint controller.
- Disable Master AXI clock on endpoint controllers to save power when
link is idle or in L1.x.
- Expose link state transition counts via debugfs to help debug
issues with low-power states.
- Add auto-loading module support.
Synopsys DesignWare PCIe controller driver:
- Remove a dependency on ZONE_DMA32 by allocating the MSI target page
differently. There's more work to do related to eDMA controllers,
so it's not completely settled"

"There are relatively few updates this cycle; half the cycle was eaten
by a grue, the other half was eaten by a tricky data corruption issue
that I still haven't entirely solved.
Hence there's no major changes in this cycle and it's largely just
minor cleanups and small bug fixes:
- fixes for filesystem shutdown procedure during a DAX memory failure
notification
- bug fixes
- logic cleanups
- log message cleanups
- updates to use vfs{g,u}id_t helpers where appropriate"

f2fs-for-6.1-rc1
This round looks fairly small comparing to the previous updates which includes
mostly minor bug fixes. Nevertheless, as we've still interested in improving
the stability, Chao added some debugging methods to diagnoze subtle runtime
inconsistency problem.
Enhancement
- store all the corruption or failure reasons in superblock
- detect meta inode, summary info, and block address inconsistency
- increase the limit for reserve_root for low-end devices
- add the number of compressed IO in iostat
Bug fix
- DIO write fix for zoned devices
- do out-of-place writes for cold files
- fix some stat updates (FS_CP_DATA_IO, dirty page count)
- fix race condition on setting FI_NO_EXTENT flag
- fix data races when freezing super
- fix wrong continue condition check in GC
- do not allow ATGC for LFS mode
In addition, there're some code enhancement and clean-ups as usual.

New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths. For optimizations by PMEM drivers, DRM drivers, etc. - vma merging improvements from Jakub Matěn. - NUMA hinting cleanups from David Hildenbrand. - xu xin added aditional userspace visibility into KSM merging activity. - THP & KSM code consolidation from Qi Zheng. - more folio work from Matthew Wilcox. - KASAN updates from Andrey Konovalov. - DAMON cleanups from Kaixu Xia. - DAMON work from SeongJae Park: fixes, cleanups. - hugetlb sysfs cleanups from Muchun Song. - Mike Kravetz fixes locking issues in hugetlbfs and in hugetlb core.
