2023-08-09net: ptp: create a mock-up PTP Hardware Clock driverVladimir Oltean3-0/+187
There are several cases where virtual net devices may benefit from having a PTP clock, and these have to do with testing. I can see at least netdevsim and veth as potential users of a common mock-up PTP hardware clock driver. The proposed idea is to create an object which emulates PTP clock operations on top of the unadjustable CLOCK_MONOTONIC_RAW plus a software-controlled time domain via a timecounter/cyclecounter and then link that PHC to the netdevsim device. The driver is fully functional for its intended purpose, and it successfully passes the PTP selftests. $ cd tools/testing/selftests/ptp/ $ ./phc.sh /dev/ptp2 TEST: settime [ OK ] TEST: adjtime [ OK ] TEST: adjfreq [ OK ] Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Link: https://lore.kernel.org/r/20230807193324.4128292-7-vladimir.oltean@nxp.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-07-18ptp: Explicitly include correct DT includesRob Herring1-1/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-03-17ptp: kvm: Use decrypted memory in confidential guest on x86Jeremi Piotrowski3-11/+53
KVM_HC_CLOCK_PAIRING currently fails inside SEV-SNP guests because the guest passes an address to static data to the host. In confidential computing the host can't access arbitrary guest memory so handling the hypercall runs into an "rmpfault". To make the hypercall work, the guest needs to explicitly mark the memory as decrypted. Do that in kvm_arch_ptp_init(), but retain the previous behavior for non-confidential guests to save us from having to allocate memory. Add a new arch-specific function (kvm_arch_ptp_exit()) to free the allocation and mark the memory as encrypted again.

2023-02-22ptp: vclock: use mutex to fix "sleep on atomic" bugÍñigo Huguet2-23/+23
vclocks were using spinlocks to protect access to its timecounter and cyclecounter. Access to timecounter/cyclecounter is backed by the same driver callbacks that are used for non-virtual PHCs, but the usage of the spinlock imposes a new limitation that didn't exist previously: now they're called in atomic context so they mustn't sleep. Some drivers like sfc or ice may sleep on these callbacks, causing errors like "BUG: scheduling while atomic: ptp5/25223/0x00000002" Fix it replacing the vclock's spinlock by a mutex. It fix the mentioned bug and it doesn't introduce longer delays. I've tested synchronizing various different combinations of clocks: - vclock->sysclock - sysclock->vclock - vclock->vclock - hardware PHC in different NIC -> vclock - created 4 vclocks and launch 4 parallel phc2sys processes with lockdep enabled In all cases, comparing the delays reported by phc2sys, they are in the same range of values than before applying the patch.

1588 driver loses about 1us in adjtime operation at PTP slave This is because adjtime operation uses a slow non-atomic tmr_cnt_read() followed by tmr_cnt_write() operation. In the above sequence, since the timer counter operation keeps incrementing, it leads to latency. The tmr_offset register (which is added to TMR_CNT_H/L register giving the current time) must be programmed with the delta nanoseconds.

For bus-based driver, device removal is implemented as: 1 device_remove()-> 2 bus->remove()-> 3 driver->remove() Driver core needs no inform from callee(bus driver) about the result of remove callback. In that case, commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned. Now we have the situation that both 1 & 2 of calling chain are void-returned, so it does not make much sense for 3(driver->remove) to return non-void to its caller. So the basic idea behind this change is making remove() callback of any bus-based driver to be void-returned. This change, for itself, is for device drivers based on acpi-bus.

Convert all remaining drivers that still use .adjfreq to the newer .adjfine implementation. These drivers are not straightforward, as they use non-standard methods of programming their hardware. They are all converted to use scaled_ppm_to_ppb to get the parts per billion value that their logic depends on.
