2024-07-05Merge v6.10-rc6 into drm-nextDaniel Vetter
The exynos-next pull is based on a newer -rc than drm-next. hence backmerge first to make sure the unrelated conflicts we accumulated don't end up randomly in the exynos merge pull, but are separated out. Conflicts are all benign: Adjacent changes in amdgpu and fbdev-dma code, and cherry-pick conflict in xe. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2024-07-03drm/exynos/vidi: convert to struct drm_edidJani Nikula
Prefer the struct drm_edid based functions for storing the EDID and updating the connector. It would be better if the vidi connection ioctl passed in the EDID size separately instead of relying on the extension count specified in the EDID, but that's what we have to rely on.

Avoid assigning fake_edid_info to ctx->raw_edid. Always keep ctx->raw_edid either an allocated pointer or NULL. Defer fake_edid_info handling to .get_modes().

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into exynos-drm-next Regression fix - Fix an regression issue by adding 640x480 fallback mode for Exynos HDMI driver. Bug fix - Fix a memory leak by ensuring the duplicated EDID is properly freed in the get_modes function. Code cleanup - Remove redundant driver owner initialization since platform_driver_register() sets it automatically.

2024-06-30ata: ahci: Clean up sysfs file on errorNiklas Cassel
.probe() (ahci_init_one()) calls sysfs_add_file_to_group(), however, if probe() fails after this call, we currently never call sysfs_remove_file_from_group(). (The sysfs_remove_file_from_group() call in .remove() (ahci_remove_one()) does not help, as .remove() is not called on .probe() error.) Thus, if probe() fails after the sysfs_add_file_to_group() call, the next time we insmod the module we will get: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:04.0/remapped_nvme' CPU: 11 PID: 954 Comm: modprobe Not tainted 6.10.0-rc5 #43 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-2.fc40 04/01/2014 Call Trace: <TASK> dump_stack_lvl+0x5d/0x80 sysfs_warn_dup.cold+0x17/0x23 sysfs_add_file_mode_ns+0x11a/0x130 sysfs_add_file_to_group+0x7e/0xc0 ahci_init_one+0x31f/0xd40 [ahci] Fixes: 894fba7f434a ("ata: ahci: Add sysfs attribute to show remapped NVMe device count") Cc: stable@vger.kernel.org Reviewed-by: Damien Le Moal <dlemoal@kernel.org> Reviewed-by: Hannes Reinecke <hare@suse.de> Link: https://lore.kernel.org/r/20240629124210.181537-10-cassel@kernel.org Signed-off-by: Niklas Cassel <cassel@kernel.org>

2024-06-30x86-32: fix cmpxchg8b_emu build error with clangLinus Torvalds
The kernel test robot reported that clang no longer compiles the 32-bit x86 kernel in some configurations due to commit 95ece48165c1 ("locking/atomic/x86: Rewrite x86_32 arch_atomic64_{,fetch}_{and,or,xor}() functions"). The build fails with arch/x86/include/asm/cmpxchg_32.h:149:9: error: inline assembly requires more registers than available and the reason seems to be that not only does the cmpxchg8b instruction need four fixed registers (EDX:EAX and ECX:EBX), with the emulation fallback the inline asm also wants a fifth fixed register for the address (it uses %esi for that, but that's just a software convention with cmpxchg8b_emu). Avoiding using another pointer input to the asm (and just forcing it to use the "0(%esi)" addressing that we end up requiring for the sw fallback) seems to fix the issue.

2024-06-28x86: stop playing stack games in profile_pc()Linus Torvalds
The 'profile_pc()' function is used for timer-based profiling, which isn't really all that relevant any more to begin with, but it also ends up making assumptions based on the stack layout that aren't necessarily valid. Basically, the code tries to account the time spent in spinlocks to the caller rather than the spinlock, and while I support that as a concept, it's not worth the code complexity or the KASAN warnings when no serious profiling is done using timers anyway these days. And the code really does depend on stack layout that is only true in the simplest of cases. We've lost the comment at some point (I think when the 32-bit and 64-bit code was unified), but it used to say: Assume the lock function has either no stack frame or a copy of eflags from PUSHF. which explains why it just blindly loads a word or two straight off the stack pointer and then takes a minimal look at the values to just check if they might be eflags or the return pc: Eflags always has bits 22 and up cleared unlike kernel addresses but that basic stack layout assumption assumes that there isn't any lock debugging etc going on that would complicate the code and cause a stack frame. It causes KASAN unhappiness reported for years by syzkaller [1] and others [2]. With no real practical reason for this any more, just remove the code. Just for historical interest, here's some background commits relating to this code from 2006: 0cb91a229364 ("i386: Account spinlocks to the caller during profiling for !FP kernels") 31679f38d886 ("Simplify profile_pc on x86-64") and a code unification from 2009: ef4512882dbe ("x86: time_32/64.c unify profile_pc") but the basics of this thing actually goes back to before the git tree.

2024-06-28drm/xe/mcr: Avoid clobbering DSS steeringMatt Roper
A couple copy/paste mistakes in the code that selects steering targets for OADDRM and INSTANCE0 unintentionally clobbered the steering target for DSS ranges in some cases. The OADDRM/INSTANCE0 values were also not assigned as intended, although that mistake wound up being harmless since the desired values for those specific ranges were '0' which the kzalloc of the GT structure should have already taken care of implicitly.

It's not very obvious what the difference is between the 'size' and 'n_entries' fields of the MOCS structure.

2024-06-28drm/xe/mocs: Update MOCS assertions and remove redundant checksMatt Roper
Rely more heavily on assertions to describe the MOCS programming invariants. CI checks these assertions and will ensure no violations sneak in due to programmer error, so we can remove some of the redundant WARN and silent return checks from non-debug builds. Also tweak/augment some of the existing assertions: there's no reason we'd ever want a platform not to have a MOCS 'ops' structure hooked up so ensure info->ops is non-NULL. Likewise, we should never have a case where the bspec-defined MOCS setting table is larger than the number of MOCS registers exposed by the hardware, so add an extra assert on those sizes as well.
