ASoC: SOF: use hdac_bus to manage streams - #52

This patch doesn't replace struct sof_intel_hda_dev with hda_bus, but embed hda_bus in sof_intel_hda_dev. It's becasue there are a few memebers of sof_intel_hda_dev are not in hda_bus. Host streams are managed by hdac_bus's stream_list now. Compiling okay. But not test yet. May have conflict with Keyon's PR today. I'll rebase and merge it to Keyon's PR later.

[ Upstream commit 031af50 ] The inline assembly for arm64's cmpxchg_double*() implementations use a +Q constraint to hazard against other accesses to the memory location being exchanged. However, the pointer passed to the constraint is a pointer to unsigned long, and thus the hazard only applies to the first 8 bytes of the location. GCC can take advantage of this, assuming that other portions of the location are unchanged, leading to a number of potential problems. This is similar to what we fixed back in commit: fee960b ("arm64: xchg: hazard against entire exchange variable") ... but we forgot to adjust cmpxchg_double*() similarly at the same time. The same problem applies, as demonstrated with the following test: | struct big { | u64 lo, hi; | } __aligned(128); | | unsigned long foo(struct big *b) | { | u64 hi_old, hi_new; | | hi_old = b->hi; | cmpxchg_double_local(&b->lo, &b->hi, 0x12, 0x34, 0x56, 0x78); | hi_new = b->hi; | | return hi_old ^ hi_new; | } ... which GCC 12.1.0 compiles as: | 0000000000000000 <foo>: | 0: d503233f paciasp | 4: aa0003e4 mov x4, x0 | 8: 1400000e b 40 <foo+0x40> | c: d2800240 mov x0, #0x12 // thesofproject#18 | 10: d2800681 mov x1, #0x34 // thesofproject#52 | 14: aa0003e5 mov x5, x0 | 18: aa0103e6 mov x6, x1 | 1c: d2800ac2 mov x2, #0x56 // thesofproject#86 | 20: d2800f03 mov x3, #0x78 // thesofproject#120 | 24: 48207c82 casp x0, x1, x2, x3, [x4] | 28: ca050000 eor x0, x0, x5 | 2c: ca060021 eor x1, x1, x6 | 30: aa010000 orr x0, x0, x1 | 34: d2800000 mov x0, #0x0 // #0 <--- BANG | 38: d50323bf autiasp | 3c: d65f03c0 ret | 40: d2800240 mov x0, #0x12 // thesofproject#18 | 44: d2800681 mov x1, #0x34 // thesofproject#52 | 48: d2800ac2 mov x2, #0x56 // thesofproject#86 | 4c: d2800f03 mov x3, #0x78 // thesofproject#120 | 50: f9800091 prfm pstl1strm, [x4] | 54: c87f1885 ldxp x5, x6, [x4] | 58: ca0000a5 eor x5, x5, x0 | 5c: ca0100c6 eor x6, x6, x1 | 60: aa0600a6 orr x6, x5, x6 | 64: b5000066 cbnz x6, 70 <foo+0x70> | 68: c8250c82 stxp w5, x2, x3, [x4] | 6c: 35ffff45 cbnz w5, 54 <foo+0x54> | 70: d2800000 mov x0, #0x0 // #0 <--- BANG | 74: d50323bf autiasp | 78: d65f03c0 ret Notice that at the lines with "BANG" comments, GCC has assumed that the higher 8 bytes are unchanged by the cmpxchg_double() call, and that `hi_old ^ hi_new` can be reduced to a constant zero, for both LSE and LL/SC versions of cmpxchg_double().

When there are memory-only nodes (nodes without CPUs), these nodes are not properly initialized, causing kernel panic during boot. of_numa_init of_numa_parse_cpu_nodes node_set(nid, numa_nodes_parsed); of_numa_parse_memory_nodes In of_numa_parse_cpu_nodes, numa_nodes_parsed gets updated only for nodes containing CPUs. Memory-only nodes should have been updated in of_numa_parse_memory_nodes, but they weren't. Subsequently, when free_area_init() attempts to access NODE_DATA() for these uninitialized memory nodes, the kernel panics due to NULL pointer dereference. This can be reproduced on ARM64 QEMU with 1 CPU and 2 memory nodes: qemu-system-aarch64 \ -cpu host -nographic \ -m 4G -smp 1 \ -machine virt,accel=kvm,gic-version=3,iommu=smmuv3 \ -object memory-backend-ram,size=2G,id=mem0 \ -object memory-backend-ram,size=2G,id=mem1 \ -numa node,nodeid=0,memdev=mem0 \ -numa node,nodeid=1,memdev=mem1 \ -kernel $IMAGE \ -hda $DISK \ -append "console=ttyAMA0 root=/dev/vda rw earlycon" [ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x481fd010] [ 0.000000] Linux version 6.17.0-rc1-00001-gabb4b3daf18c-dirty (yintirui@local) (gcc (GCC) 12.3.1, GNU ld (GNU Binutils) 2.41) thesofproject#52 SMP PREEMPT Mon Aug 18 09:49:40 CST 2025 [ 0.000000] KASLR enabled [ 0.000000] random: crng init done [ 0.000000] Machine model: linux,dummy-virt [ 0.000000] efi: UEFI not found.

During shutdown, this non-zero n->nr_slabs is detected and reported. Specifically, the problem is that there are two checks for detecting a full partial list by comparing n->nr_partial >= s->min_partial where the latter check is affected by remove_partial() decreasing n->nr_partial between the checks. Reoganize the code so there is a single check upfront.

The xfstests' test-case generic/003 fails with errors: sudo ./check generic/003 FSTYP -- hfs PLATFORM -- Linux/x86_64 hfsplus-testing-0001 7.0.0-rc1+ thesofproject#18 SMP PREEMPT_DYNAMIC Fri Mar 13 17:54:19 PDT 2026 MKFS_OPTIONS -- /dev/loop51 MOUNT_OPTIONS -- /dev/loop51 /mnt/scratch output mismatch QA output created by 003 ERROR: access time has changed for file1 after remount ERROR: access time has changed after modifying file1 ERROR: change time has not been updated after changing file1 ERROR: access time has changed for file in read-only filesystem Silence is golden This patch fixes the issue with change time by adding inode_set_ctime_current() and mark_inode_dirty() in hfs_rename(). Also, it reworks hfs_inode_setattr() by changing simple_inode_init_ts() on inode_set_mtime_to_ts() and inode_set_ctime_current() calls. HFS hasn't any field in on-disk layout that can keep the file/folder access times (atime). It was added setting of SB_NOATIME in SB_NOATIME. Finally, we have only atime related errors in generic/003 output: sudo ./check generic/003 FSTYP -- hfs PLATFORM -- Linux/x86_64 hfsplus-testing-0001 7.1.0-rc1+ thesofproject#52 SMP PREEMPT_DYNAMIC Wed May 13 15:04:37 PDT 2026 MKFS_OPTIONS -- /dev/loop51 MOUNT_OPTIONS -- /dev/loop51 /mnt/scratch QA output created by 003 ERROR: access time has not been updated after accessing file1 first time ERROR: access time has not been updated after accessing file2 ERROR: access time has not been updated after accessing file3 second time ERROR: access time has not been updated after accessing file3 third time Silence is golden The generic/003 test-case needs to be disabled for HFS case because it cannot support the file/folder access times (atime).

This patch doesn't replace struct sof_intel_hda_dev with hda_bus, but
embed hda_bus in sof_intel_hda_dev. It's becasue there are a few memebers
of sof_intel_hda_dev are not in hda_bus.
Host streams are managed by hdac_bus's stream_list now.
Compiling okay. But not test yet. May have conflict with Keyon's PR today.
I'll rebase and merge it to Keyon's PR later.
