| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cpufreq_get_hw_max_freq() returns max frequency in kHz as *unsigned int*, while freq_inv_set_max_ratio() gets passed this frequency in Hz as 'u64'. Multiplying max frequency by 1000 can potentially result in overflow -- multiplying by 1000ULL instead should avoid that...

The new KPTI rewrite code uses __create_pgd_mapping() to create a temporary pagetable. This happens in atomic context, after secondary CPUs are brought up and the kernel has left the SYSTEM_BOOTING state. Hence we try to acquire a mutex in atomic context, which is generally unsound (though benign in this case as the mutex should be free and all other CPUs are quiescent). This patch avoids the issue by pulling the mutex out of alloc_init_pud() and calling it at a higher level in the pagetable manipulation code. This allows it to be used without locking where one CPU is known to be in exclusive control of the machine, even after having left the SYSTEM_BOOTING state.

The biggest change here is that riscv_cbom_block_size is no longer initialized, as IMO the default isn't sane: there's nothing in the ISA that mandates any specific cache block size, so falling back to one will just silently produce the wrong answer on some systems. This also changes the probing order so the cache block size is known before enabling Zicbom support.

This also covers the "XSAVE not supported" check, as setting CR4.OSXSAVE=1 #GPs if XSAVE is not supported (and userspace gets to keep the pieces if it forces incoherent vCPU state). Add a comment to kvm_emulate_xsetbv() to call out that the CPU checks CR4.OSXSAVE before checking for intercepts. AMD'S APM implies that #UD has priority (says that intercepts are checked before #GP exceptions), while Intel's SDM says nothing about interception priority. However, testing on hardware shows that both AMD and Intel CPUs prioritize the #UD over interception.

Failing to allow FP+SSE first showed up as a QEMU live migration failure, where migrating a VM from a pre-XSAVE host, e.g. Nehalem, to an XSAVE host failed due to KVM rejecting KVM_SET_XSAVE. However, the bug also causes problems even when migrating between XSAVE-capable hosts as KVM_GET_SAVE won't set any bits in user_xfeatures if XSAVE isn't exposed to the guest, i.e. KVM will fail to actually migrate FP+SSE. Because KVM_{G,S}ET_XSAVE are designed to allowing migrating between hosts with and without XSAVE, KVM_GET_XSAVE on a non-XSAVE (by way of fpu_copy_guest_fpstate_to_uabi()) always sets the FP+SSE bits in the header so that KVM_SET_XSAVE will work even if the new host supports XSAVE.

If userspace never invokes KVM_SET_CPUID2, supported XCR0 will be '0', whereas the allowed user XFEATURES will be non-zero. Practically speaking, the edge case likely doesn't matter as no sane userspace will live migrate a VM without ever doing KVM_SET_CPUID2. The primary motivation is to prepare for KVM intentionally and explicitly setting bits in user_xfeatures that are not set in guest_supported_xcr0. Because KVM_{G,S}ET_XSAVE can be used to svae/restore FP+SSE state even if the host doesn't support XSAVE, KVM needs to set the FP+SSE bits in user_xfeatures even if they're not allowed in XCR0, e.g. because XCR0 isn't exposed to the guest. At that point, the simplest fix is to track the two things separately (allowed save/restore vs. allowed XCR0).

The kmemleak_free_part() therefore no longer worked as expected on physically allocated objects (hyp_mem_base in this case) as it attempted to search and remove things in object_tree_root tree. Fix it by using kmemleak_free_part_phys() to unregister hyp_mem_base. This fixes an immediate crash when booting a KVM host in protected mode with kmemleak enabled.

This causes an issue with one Toradex SKU that uses a consumer-grade chip that is capable of going up to 1.8GHz at 1.00V. Extend the ranges to min/max values of the SoC operating ranges (table 10) in the datasheet. Detailed explanation as follows: BUCK2: - As already described above, the SKU with the consumer-grade chip needs a voltage of at least 1.00V. 1.05V is chosen now as this is listed as the maximum. Both industrial and consumer-grade chips have an absolute maximum rating of 1.15V which makes it still safe to put 1.05V - Lower the regulator-min value to the smallest value allowed from the Quad-A53, 1.2GHz version of the SoC BUCK3: - This regulator is used for SoC input voltages VDD_GPU, VDD_VPU and VDD_DRAM. - Use the smallest value of these three inputs as the regulator-min - Use the largest value of these three inputs as the regulator-max LDO2: - This LDO is used for VDD_SNVS_0P8 SoC input voltage. As this has a single nominal input voltage just put this in the middle of 0.8V.

This is especially important on systems with PSR-enabled panels (like Gru-Kevin), since we make heavy, constant use of AUX. According to Rockchip, using any rate other than 24 MHz can cause "problems between syncing the PHY an PCLK", which leads to all sorts of unreliabilities around register operations.

The production/vendor kernel specified the pin configuration correctly as a pull-up, but this didn't get ported correctly to upstream. This means Bob's WLAN_HOST_WAKE# pin is floating, causing inconsistent wakeup behavior. Note that bt_host_wake_l has a similar dynamic, but apparently the upstream choice was to redundantly configure both internal and external pull-up on Kevin (see the "Kevin has an external pull up" comment in rk3399-gru.dtsi). This doesn't cause any functional problem, although it's perhaps wasteful.

This was fixed for x86 in commit ffcf9c5700e4 ("x86: link vdso and boot with -z noexecstack --no-warn-rwx-segments"), but remained broken for UML, resulting in several warnings: /usr/bin/ld: warning: arch/x86/um/vdso/vdso.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /usr/bin/ld: warning: .tmp_vmlinux.kallsyms1 has a LOAD segment with RWX permissions /usr/bin/ld: warning: .tmp_vmlinux.kallsyms1.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /usr/bin/ld: warning: .tmp_vmlinux.kallsyms2 has a LOAD segment with RWX permissions /usr/bin/ld: warning: .tmp_vmlinux.kallsyms2.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /usr/bin/ld: warning: vmlinux has a LOAD segment with RWX permissions Link both the VDSO and vmlinux with -z noexecstack, fixing the warnings about .note.GNU-stack sections. In addition, pass --no-warn-rwx-segments to dodge the remaining warnings about LOAD segments with RWX permissions in the kallsyms objects. (Note that this flag is apparently not available on lld, so hide it behind a test for BFD, which is what the x86 patch does.)
