* arm/arm64: KVM: Advertise SMCCC v1.1Marc Zyngier2018-02-061-1/+1
| | | | | | | | | | | | | The new SMC Calling Convention (v1.1) allows for a reduced overhead when calling into the firmware, and provides a new feature discovery mechanism. Make it visible to KVM guests.

* arm: KVM: Fix SMCCC handling of unimplemented SMC/HVC callsMarc Zyngier2018-02-061-2/+11
| | | | | | | | | | | | | | | KVM doesn't follow the SMCCC when it comes to unimplemented calls, and inject an UNDEF instead of returning an error. Since firmware calls are now used for security mitigation, they are becoming more common, and the undef is counter productive. Instead, let's follow the SMCCC which states that -1 must be returned to the caller when getting an unknown function number.

* KVM: arm64: Handle RAS SErrors from EL1 on guest exitJames Morse2018-01-161-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We expect to have firmware-first handling of RAS SErrors, with errors notified via an APEI method. For systems without firmware-first, add some minimal handling to KVM. There are two ways KVM can take an SError due to a guest, either may be a RAS error: we exit the guest due to an SError routed to EL2 by HCR_EL2.AMO, or we take an SError from EL2 when we unmask PSTATE.A from __guest_exit. For SError that interrupt a guest and are routed to EL2 the existing behaviour is to inject an impdef SError into the guest. Add code to handle RAS SError based on the ESR. For uncontained and uncategorized errors arm64_is_fatal_ras_serror() will panic(), these errors compromise the host too. All other error types are contained: For the fatal errors the vCPU can't make progress, so we inject a virtual SError. We ignore contained errors where we can make progress as if we're lucky, we may not hit them again. If only some of the CPUs support RAS the guest will see the cpufeature sanitised version of the id registers, but we may still take RAS SError on this CPU. Move the SError handling out of handle_exit() into a new handler that runs before we can be preempted. This allows us to use this_cpu_has_cap(), via arm64_is_ras_serror().

* KVM: arm/arm64: mask/unmask daif around VHE guestsJames Morse2018-01-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | Non-VHE systems take an exception to EL2 in order to world-switch into the guest. When returning from the guest KVM implicitly restores the DAIF flags when it returns to the kernel at EL1. With VHE none of this exception-level jumping happens, so KVMs world-switch code is exposed to the host kernel's DAIF values, and KVM spills the guest-exit DAIF values back into the host kernel. On entry to a guest we have Debug and SError exceptions unmasked, KVM has switched VBAR but isn't prepared to handle these. On guest exit Debug exceptions are left disabled once we return to the host and will stay this way until we enter user space. Add a helper to mask/unmask DAIF around VHE guests. The unmask can only happen after the hosts VBAR value has been synchronised by the isb in __vhe_hyp_call (via kvm_call_hyp()). Masking could be as late as setting KVMs VBAR value, but is kept here for symmetry.

* arm64: allow ID map to be extended to 52 bitsKristina Martsenko2017-12-221-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when using VA_BITS < 48, if the ID map text happens to be placed in physical memory above VA_BITS, we increase the VA size (up to 48) and create a new table level, in order to map in the ID map text. This is okay because the system always supports 48 bits of VA. This patch extends the code such that if the system supports 52 bits of VA, and the ID map text is placed that high up, then we increase the VA size accordingly, up to 52. One difference from the current implementation is that so far the condition of VA_BITS < 48 has meant that the top level table is always "full", with the maximum number of entries, and an extra table level is always needed. Now, when VA_BITS = 48 (and using 64k pages), the top level table is not full, and we simply need to increase the number of entries in it, instead of creating a new table level.

* arm64: handle 52-bit addresses in TTBRKristina Martsenko2017-12-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The top 4 bits of a 52-bit physical address are positioned at bits 2..5 in the TTBR registers. Introduce a couple of macros to move the bits there, and change all TTBR writers to use them. Leave TTBR0 PAN code unchanged, to avoid complicating it. A system with 52-bit PA will have PAN anyway (because it's ARMv8.1 or later), and a system without 52-bit PA can only use up to 48-bit PAs. A later patch in this series will add a kconfig dependency to ensure PAN is configured. In addition, when using 52-bit PA there is a special alignment requirement on the top-level table. We don't currently have any VA_BITS configuration that would violate the requirement, but one could be added in the future, so add a compile-time BUG_ON to check for it.

The GPIO interrupt controller however specifies the register offset without subtracting the "cbus" base address. This leads to a problem where of_iomap inside the irq-meson-gpio driver fails because it actually tries to map 0x182209880 (cbus base = 0xc1100000 + 0xc1109880 for the GPIO interrupt controller).

This issue happens in cpuidle states C2 and C3 and does not happen if cpuidle is limited to C1 state only. The symptoms are that the whole system hangs and never wakes up from idle, and if a watchdog is configured the system reboots after a while. Turns out that OHCI/EHCI devices on omap4 are trying to use the GIC interrupt controller directly as a parent instead of the WUGEN. We need to pass the interrupts through WUGEN to GIC to provide the wakeup events for the processor. Let's fix the issue by removing the gic interrupt-parent and use the default interrupt-parent wakeupgen instead. Note that omap5.dtsi had this already fixes earlier by commit 7136d457f365 ("ARM: omap: convert wakeupgen to stacked domains") but we somehow missed omap4 at that point.

Fix by adding the CM offset into the calculation so the wait_module_ready will access correct register.

This is not present in any of the other power domains. Hence remove the generic am33xx_pwrdm_read_prev_pwrst hook which wrongly reads the reserved bit fields for all the other power domains. Reading the reserved bits leads to wrongly interpreting the low power transitions for various power domains that do not have the LastPowerStateEntered field.

After investigating it turned out that n900 save_secure_ram_context does some whacky virtual to physical address translation for the SRAM data address. As we now only have minimal parts of omap3 idle code copied to SRAM, running save_secure_ram_context() in SRAM is not needed. It only gets called on PM init. And it seems there's no need to ever call this from SRAM idle code. So let's just keep save_secure_ram_context() in DDR, and pass it the physical address of the parameters. We can do everything else in omap-secure.c like we already do for other secure code. And since we don't have any documentation, I still have no clue what the values for 0, 1 and 1 for the parameters might be. If somebody has figured it out, please do send a patch to add some comments. Debugged-by: Joonsoo Kim <iamjoonsoo.kim@lge.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
