AngeloGioacchino Del Regno authored
Similarly to what can be seen in MT8192, on MT8195 the mfg_core_tmp clock is a mux used to switch between different "safe" (and slower) clock sources for the GPU: this is used during MFGPLL reconfiguration and eventually during idling at very low frequencies. This clock getting turned off means that the GPU will occasionally be unclocked, producing obvious consequences such as system crash or unpredictable behavior: assigning it to the top level MFG power domain will make sure that this stays on at all times during any operation on the MFG domain (only GPU-related transactions).

Add coupling for these regulators, as VSRAM_OTHER is used to power the GPU SRAM, and they have a strict voltage output relation to satisfy in order to ensure GPU stable operation. While at it, also add voltage constraint overrides for the GPU SRAM regulator "mt6359_vsram_others" so that we stay in a safe range of 0.75-0.80V. Signed-off-by:

The MT8192 SoC specifies a maximum voltage for the GPU's digital supply of 0.88V and the GPU OPPs are declaring a maximum voltage of 0.80V. In order to keep the GPU voltage in the safe range, change the maximum voltage for mt6315@7's vbuck1 to 0.80V as sending, for any mistake, 1.193V would be catastrophic.

Commit aa47a7c2 ("lib/cpumask: deprecate nr_cpumask_bits") resulted in the cpumask operations potentially becoming hugely less efficient, because suddenly the cpumask was always considered to be variable-sized. The optimization was then later added back in a limited form by commit 6f9c07be ("lib/cpumask: add FORCE_NR_CPUS config option"), but that FORCE_NR_CPUS option is not useful in a generic kernel and more of a special case for embedded situations with fixed hardware. Instead, just re-introduce the optimization, with some changes. Instead of depending on CPUMASK_OFFSTACK being false, and then always using the full constant cpumask width, this introduces three different cpumask "sizes": - the exact size (nr_cpumask_bits) remains identical to nr_cpu_ids. This is used for situations where we should use the exact size. - the "small" size (small_cpumask_bits) is the NR_CPUS constant if it fits in a single word and the bitmap operations thus end up able to trigger the "small_const_nbits()" optimizations. This is used for the operations that have optimized single-word cases that get inlined, notably the bit find and scanning functions. - the "large" size (large_cpumask_bits) is the NR_CPUS constant if it is an sufficiently small constant that makes simple "copy" and "clear" operations more efficient. This is arbitrarily set at four words or less. As a an example of this situation, without this fixed size optimization, cpumask_clear() will generate code like movl nr_cpu_ids(%rip), %edx addq $63, %rdx shrq $3, %rdx andl $-8, %edx callq memset@PLT on x86-64, because it would calculate the "exact" number of longwords that need to be cleared. In contrast, with this patch, using a MAX_CPU of 64 (which is quite a reasonable value to use), the above becomes a single movq $0,cpumask instruction instead, because instead of caring to figure out exactly how many CPU's the system has, it just knows that the cpumask will be a single word and can just clear it all. Note that this does end up tightening the rules a bit from the original version in another way: operations that set bits in the cpumask are now limited to the actual nr_cpu_ids limit, whereas we used to do the nr_cpumask_bits thing almost everywhere in the cpumask code. But if you just clear bits, or scan for bits, we can use the simpler compile-time constants. In the process, remove 'cpumask_complement()' and 'for_each_cpu_not()' which were not useful, and which fundamentally have to be limited to 'nr_cpu_ids'. Better remove them now than have somebody introduce use of them later. Of course, on x86-64 with MAXSMP there is no sane small compile-time constant for the cpumask sizes, and we end up using the actual CPU bits, and will generate the above kind of horrors regardless. Please don't use MAXSMP unless you really expect to have machines with thousands of cores. Signed-off-by:

Pull VM_FAULT_RETRY fixes from Al Viro: "Some of the page fault handlers do not deal with the following case correctly: - handle_mm_fault() has returned VM_FAULT_RETRY - there is a pending fatal signal - fault had happened in kernel mode Correct action in such case is not "return unconditionally" - fatal signals are handled only upon return to userland and something like copy_to_user() would end up retrying the faulting instruction and triggering the same fault again and again. What we need to do in such case is to make the caller to treat that as failed uaccess attempt - handle exception if there is an exception handler for faulting instruction or oops if there isn't one. Over the years some architectures had been fixed and now are handling that case properly; some still do not. This series should fix the remaining ones.

include/linux/compiler-intel.h had no update in the past 3 years. We often forget about the third C compiler to build the kernel. For example, commit a0a12c3e ("asm goto: eradicate CC_HAS_ASM_GOTO") only mentioned GCC and Clang. init/Kconfig defines CC_IS_GCC and CC_IS_CLANG but not CC_IS_ICC, and nobody has reported any issue. I guess the Intel Compiler support is broken, and nobody is caring about it. Harald Arnesen pointed out ICC (classic Intel C/C++ compiler) is deprecated: $ icc -v icc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is deprecated and will be removed from product release in the second half of 2023. The Intel(R) oneAPI DPC++/C++ Compiler (ICX) is the recommended compiler moving forward. Please transition to use this compiler.

The migration code ends up temporarily stashing information of the wrong type in unused fields of the newly allocated destination folio. That all works fine, but gcc does complain about the pointer type mis-use: mm/migrate.c: In function ‘__migrate_folio_extract’: mm/migrate.c:1050:20: note: randstruct: casting between randomized structure pointer types (ssa): ‘struct anon_vma’ and ‘struct address_space’ 1050 | *anon_vmap = (void *)dst->mapping; | ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~ and gcc is actually right to complain since it really doesn't understand that this is a very temporary special case where this is ok. This could be fixed in different ways by just obfuscating the assignment sufficiently that gcc doesn't see what is going on, but the truly "proper C" way to do this is by explicitly using a union. Using unions for type conversions like this is normally hugely ugly and syntactically nasty, but this really is one of the few cases where we want to make it clear that we're not doing type conversion, we're really re-using the value bit-for-bit just using another type. IOW, this should not become a common pattern, but in this one case using that odd union is probably the best way to document to the compiler what is conceptually going on here. [ Side note: there are valid cases where we convert pointers to other pointer types, notably the whole "folio vs page" situation, where the types actually have fundamental commonalities. The fact that the gcc note is limited to just randomized structures means that we don't see equivalent warnings for those cases, but it migth also mean that we miss other cases where we do play these kinds of dodgy games, and this kind of explicit conversion might be a good idea. ] I verified that at least for an allmodconfig build on x86-64, this generates the exact same code, apart from line numbers and assembler comment changes.
