git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic fixes from Arnd Bergmann: "There is one build fix for Arm platforms that ended up impacting most architectures because of the way the drivers/firmware Kconfig file is wired up: The CONFIG_QCOM_SCM dependency have caused a number of randconfig regressions over time, and some still remain in v5.15-rc4. The fix we agreed on in the end is to make this symbol selected by any driver using it, and then building it even for non-Arm platforms with CONFIG_COMPILE_TEST. To make this work on all architectures, the drivers/firmware/Kconfig file needs to be included for all architectures to make the symbol itself visible. In a separate discussion, we found that a sound driver patch that is pending for v5.16 needs the same change to include this Kconfig file, so the easiest solution seems to have my Kconfig rework included in v5.15. Finally, the branch also includes a small unrelated build fix for NOMMU architectures" Link: https://lore.kernel.org/all/20210928153508.101208f8@canb.auug.org.au/ Link: https://lore.kernel.org/all/20210928075216.4193128-1-arnd@kernel.org/ Link: https://lore.kernel.org/all/20211007151010.333516-1-arnd@kernel.org/ * tag 'asm-generic-fixes-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic/io.h: give stub iounmap() on !MMU same prototype as elsewhere qcom_scm: hide Kconfig symbol firmware: include drivers/firmware/Kconfig unconditionally

2021-10-08drm/amdkfd: rm BO resv on validation to avoid deadlockAlex Sierra
This fix the deadlock with the BO reservations during SVM_BO evictions while allocations in VRAM are concurrently performed. More specific, while the ttm waits for the fence to be signaled (ttm_bo_wait), it already has the BO reserved. In parallel, the restore worker might be running, prefetching memory to VRAM. This also requires to reserve the BO, but blocks the mmap semaphore first. The deadlock happens when the SVM_BO eviction worker kicks in and waits for the mmap semaphore held in restore worker. Preventing signal the fence back, causing the deadlock until the ttm times out. We don't need to hold the BO reservation anymore during validation and mapping. Now the physical addresses are taken from hmm_range_fault. We also take migrate_mutex to prevent range migration while validate_and_map update GPU page table.

2021-10-08drm/i915/dp: take LTTPR into account in 128b/132b ratesJani Nikula
Limit the supported UHBR rates based on the repeater support, if there are repeaters. This should be done in DP helper level, but that requires an overhaul of the LTTPR handling, as the max rate is not enough to represent how 128b/132b rates may be masked along the way. Curiously, the spec says: * Shall be cleared to 00h when operating in 8b/10b Link Layer. * Each LTTPR on the way back to the DPTX shall clear the bits that do not correspond to the LTTPR's current bit rate. It's rather vague if we can reliably use the field at this time due to the wording "operating" and "current". But it would seem bizarre to have to wait until trying to operate a 128b/132b link layer at a certain bit rate to figure this out.

2021-10-07drm/i915: remove IS_ACTIVELucas De Marchi
When trying to bring IS_ACTIVE to linux/kconfig.h I thought it wouldn't provide much value just encapsulating it in a boolean context. So I also added the support for handling undefined macros as the IS_ENABLED() counterpart. However the feedback received from Masahiro Yamada was that it is too ugly, not providing much value. And just wrapping in a boolean context is too dumb - we could simply open code it. As detailed in commit babaab2f4738 ("drm/i915: Encapsulate kconfig constant values inside boolean predicates"), the IS_ACTIVE macro was added to workaround a compilation warning. However after checking again our current uses of IS_ACTIVE it turned out there is only 1 case in which it triggers a warning in clang (due -Wconstant-logical-operand) and 2 in smatch. All the others can simply use the shorter version, without wrapping it in any macro. So here I'm dialing all the way back to simply removing the macro. That single case hit by clang can be changed to make the constant come first, so it doesn't think it's mask: - if (context && CONFIG_DRM_I915_FENCE_TIMEOUT) + if (CONFIG_DRM_I915_FENCE_TIMEOUT && context) As talked with Dan Carpenter, that logic will be added in smatch as well, so it will also stop warning about it.

2021-10-07qcom_scm: hide Kconfig symbolArnd Bergmann
Now that SCM can be a loadable module, we have to add another dependency to avoid link failures when ipa or adreno-gpu are built-in: aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe': ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available' ld.lld: error: undefined symbol: qcom_scm_is_available >>> referenced by adreno_gpu.c >>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a This can happen when CONFIG_ARCH_QCOM is disabled and we don't select QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd use a similar dependency here to what we have for QCOM_RPROC_COMMON, but that causes dependency loops from other things selecting QCOM_SCM. This appears to be an endless problem, so try something different this time: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement. According to my testing this still builds fine, and the QCOM platform selects this symbol already.
