2021-02-10ARM: dts: add Ebang EBAZ4205 device treeMichael Walle
The Ebang EBAZ4205 is a simple board based on the Xilinx Zynq-7000 SoC. Its features are: - one serial port - 256 MB RAM - 128 MB NAND flash - SDcard slot - IP101GA 10/100 Mbit Ethernet PHY (connected to PL IOs) - two LEDs (connected to PL IOs) - one Push Button (connect to PL IOs) - (optional) RTC - (optional) Input voltage supervisor The NAND flash is not supported in mainline linux yet. Unfortunately, the PHY is connected via the PL, thus for working ethernet the FPGA has to be configured. Also, depending on the board variant, the PHY has no external crystal and its clock needs to be driven by the PL. FCLK3 is used for this and is kept enabled.

2021-02-10crypto: arm64/crc-t10dif - move NEON yield to C codeArd Biesheuvel
Instead of yielding from the bowels of the asm routine if a reschedule is needed, divide up the input into 4 KB chunks in the C glue. This simplifies the code substantially, and avoids scheduling out the task with the asm routine on the call stack, which is undesirable from a CFI/instrumentation point of view.

2021-02-10crypto: arm64/aes-neonbs - remove NEON yield callsArd Biesheuvel
There is no need for elaborate yield handling in the bit-sliced NEON implementation of AES, given that skciphers are naturally bounded by the size of the chunks returned by the skcipher_walk API. So remove the yield calls from the asm code. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2021-02-10KVM: PPC: Book3S HV: Save and restore FSCR in the P9 pathFabiano Rosas
The Facility Status and Control Register is a privileged SPR that defines the availability of some features in problem state. Since it can be written by the guest, we must restore it to the previous host value after guest exit. This restoration is currently done by taking the value from current->thread.fscr, which in the P9 path is not enough anymore because the guest could context switch the QEMU thread, causing the guest-current value to be saved into the thread struct. The above situation manifested when running a QEMU linked against a libc with System Call Vectored support, which causes scv instructions to be run by QEMU early during the guest boot (during SLOF), at which point the FSCR is 0 due to guest entry. After a few scv calls (1 to a couple hundred), the context switching happens and the QEMU thread runs with the guest value, resulting in a Facility Unavailable interrupt. This patch saves and restores the host value of FSCR in the inner guest entry loop in a way independent of current->thread.fscr. The old way of doing it is still kept in place because it works for the old entry path. Signed-off-by: Fabiano Rosas <farosas@linux.ibm.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>

2021-02-10KVM: PPC: Book3S HV: Fix radix guest SLB side channelNicholas Piggin
The slbmte instruction is legal in radix mode, including radix guest mode. This means radix guests can load the SLB with arbitrary data. KVM host does not clear the SLB when exiting a guest if it was a radix guest, which would allow a rogue radix guest to use the SLB as a side channel to communicate with other guests. Fix this by ensuring the SLB is cleared when coming out of a radix guest. Only the first 4 entries are a concern, because radix guests always run with LPCR[UPRT]=1, which limits the reach of slbmte. slbia is not used (except in a non-performance-critical path) because it can clear cached translations.

2021-02-10KVM: PPC: Book3S HV: Remove support for running HPT guest on RPT host ↵Nicholas Piggin
without mixed mode support This reverts much of commit c01015091a770 ("KVM: PPC: Book3S HV: Run HPT guests on POWER9 radix hosts"), which was required to run HPT guests on RPT hosts on early POWER9 CPUs without support for "mixed mode", which meant the host could not run with MMU on while guests were running. This code has some corner case bugs, e.g., when the guest hits a machine check or HMI the primary locks up waiting for secondaries to switch LPCR to host, which they never do. This could all be fixed in software, but most CPUs in production have mixed mode support, and those that don't are believed to be all in installations that don't use this capability. So simplify things and remove support. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Tested-by: Fabiano Rosas <farosas@linux.ibm.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>

Introduce KVM_CAP_PPC_DAWR1 which can be used by QEMU to query whether KVM supports 2nd DAWR or not. The capability is by default disabled even when the underlying CPU supports 2nd DAWR.

KVM code assumes single DAWR everywhere. Add code to support 2nd DAWR. DAWR is a hypervisor resource and thus H_SET_MODE hcall is used to set/ unset it. Introduce new case H_SET_MODE_RESOURCE_SET_DAWR1 for 2nd DAWR. Also, KVM will support 2nd DAWR only if CPU_FTR_DAWR1 is set.

Power10 is introducing a second DAWR (Data Address Watchpoint Register). Use real register names (with suffix 0) from ISA for current macros and variables used by kvm. One exception is KVM_REG_PPC_DAWR. Keep it as it is because it's uapi so changing it will break userspace.

2021-02-10KVM: PPC: Book3S HV: Allow nested guest creation when L0 hv_guest_state > L1Ravi Bangoria
On powerpc, L1 hypervisor takes help of L0 using H_ENTER_NESTED hcall to load L2 guest state in cpu. L1 hypervisor prepares the L2 state in struct hv_guest_state and passes a pointer to it via hcall. Using that pointer, L0 reads/writes that state directly from/to L1 memory. Thus L0 must be aware of hv_guest_state layout of L1. Currently it uses version field to achieve this. i.e. If L0 hv_guest_state.version != L1 hv_guest_state.version, L0 won't allow nested kvm guest. This restriction can be loosened up a bit. L0 can be taught to understand older layout of hv_guest_state, if we restrict the new members to be added only at the end, i.e. we can allow nested guest even when L0 hv_guest_state.version > L1 hv_guest_state.version. Though, the other way around is not possible.

2021-02-09s390/vtime: fix inline assembly clobber listHeiko Carstens
The stck/stckf instruction used within the inline assembly within do_account_vtime() changes the condition code. This is not reflected with the clobber list, and therefore might result in incorrect code generation. It seems unlikely that the compiler could generate incorrect code considering the surrounding C code, but it must still be fixed.
