2023-02-13tpm: Add reserved memory event logEddie James
Some platforms may desire to pass the event log up to Linux in the form of a reserved memory region. In particular, this is desirable for embedded systems or baseboard management controllers (BMCs) booting with U-Boot. IBM OpenBMC BMCs will be the first user. Add support for the reserved memory in the TPM core to find the region and map it.

2023-02-13tpm_crb: Add support for CRB devices based on PlutonMatthew Garrett
Pluton is an integrated security processor present in some recent Ryzen parts. If it's enabled, it presents two devices - an MSFT0101 ACPI device that's broadly an implementation of a Command Response Buffer TPM2, and an MSFT0200 ACPI device whose functionality I haven't examined in detail yet. This patch only attempts to add support for the TPM device. There's a few things that need to be handled here. The first is that the TPM2 ACPI table uses a previously undefined start method identifier. The table format appears to include 16 bytes of startup data, which corresponds to one 64-bit address for a start message and one 64-bit address for a completion response. The second is that the ACPI tables on the Thinkpad Z13 I'm testing this on don't define any memory windows in _CRS (or, more accurately, there are two empty memory windows). This check doesn't seem strictly necessary, so I've skipped that. Finally, it seems like chip needs to be explicitly asked to transition into ready status on every command. Failing to do this means that if two commands are sent in succession without an idle/ready transition in between, everything will appear to work fine but the response is simply the original command. I'm working without any docs here, so I'm not sure if this is actually the required behaviour or if I'm missing something somewhere else, but doing this results in the chip working reliably.

2023-02-13xen/grant-dma-iommu: Implement a dummy probe_device() callbackOleksandr Tyshchenko
Update stub IOMMU driver (which main purpose is to reuse generic IOMMU device-tree bindings by Xen grant DMA-mapping layer on Arm) according to the recent changes done in the following commit 57365a04c921 ("iommu: Move bus setup to IOMMU device registration"). With probe_device() callback being called during IOMMU device registration, the uninitialized callback just leads to the "kernel NULL pointer dereference" issue during boot. Fix that by adding a dummy callback. Looks like the release_device() callback is not mandatory to be implemented as IOMMU framework makes sure that callback is initialized before dereferencing.

2023-02-13xen/pvcalls-back: fix permanently masked event channelVolodymyr Babchuk
There is a sequence of events that can lead to a permanently masked event channel, because xen_irq_lateeoi() is newer called. This happens when a backend receives spurious write event from a frontend. In this case pvcalls_conn_back_write() returns early and it does not clears the map->write counter. As map->write > 0, pvcalls_back_ioworker() returns without calling xen_irq_lateeoi(). This leaves the event channel in masked state, a backend does not receive any new events from a frontend and the whole communication stops. Move atomic_set(&map->write, 0) to the very beginning of pvcalls_conn_back_write() to fix this issue.

2023-02-13xen: Allow platform PCI interrupt to be sharedDavid Woodhouse
When we don't use the per-CPU vector callback, we ask Xen to deliver event channel interrupts as INTx on the PCI platform device. As such, it can be shared with INTx on other PCI devices. Set IRQF_SHARED, and make it return IRQ_HANDLED or IRQ_NONE according to whether the evtchn_upcall_pending flag was actually set. Now I can share the interrupt: 11: 82 0 IO-APIC 11-fasteoi xen-platform-pci, ens4 Drop the IRQF_TRIGGER_RISING. It has no effect when the IRQ is shared, and besides, the only effect it was having even beforehand was to trigger a debug message in both I/OAPIC and legacy PIC cases: [ 0.915441] genirq: No set_type function for IRQ 11 (IO-APIC) [ 0.951939] genirq: No set_type function for IRQ 11 (XT-PIC) Signed-off-by: David Woodhouse <dwmw@amazon.co.uk> Reviewed-by: Juergen Gross <jgross@suse.com> Link: https://lore.kernel.org/r/f9a29a68d05668a3636dd09acd94d970269eaec6.camel@infradead.org Signed-off-by: Juergen Gross <jgross@suse.com>
2023-02-13drivers/xen/hypervisor: Expose Xen SIF flags to userspacePer Bilse
/proc/xen is a legacy pseudo filesystem which predates Xen support getting merged into Linux. It has largely been replaced with more normal locations for data (/sys/hypervisor/ for info, /dev/xen/ for user devices). We want to compile xenfs support out of the dom0 kernel. There is one item which only exists in /proc/xen, namely /proc/xen/capabilities with "control_d" being the signal of "you're in the control domain". This ultimately comes from the SIF flags provided at VM start. This patch exposes all SIF flags in /sys/hypervisor/start_flags/ as boolean files, one for each bit, returning '1' if set, '0' otherwise. Two known flags, 'privileged' and 'initdomain', are explicitly named, and all remaining flags can be accessed via generically named files, as suggested by Andrew Cooper.

The original TPS65010 dependency was only needed for MACH_OMAP_H2, which is now gone, but I messed up the conversion when I removed that symbol. Now the missing TPS65010 causes a boot failure on other machines such as the SX1.

2023-02-11driver core: cpu: don't hand-override the uevent bus_type callback.Greg Kroah-Hartman
Instead of having to change the uevent bus_type callback by hand at runtime, set it at build time based on the build configuration options, making this much simpler to maintain and understand (and allow to make the structure constant.)
