[osv-dev] Re: [PATCH v2 2/3] virtio-pci: discover shared memory regions

I think you are trying to bite too much in this patch. I would suggest taking a more incremental approach and just implement void virtio_modern_pci_device::parse_virtio_capabilities() like you had in V1 patch and any other necessary changes to virtio_modern_pci_device() as minimal as possible t

[osv-dev] [COMMIT osv master] libc: refine how timerfd_* functions handle wall clock jumps

From: Waldemar Kozaczuk Committer: Waldemar Kozaczuk Branch: master libc: refine how timerfd_* functions handle wall clock jumps This patch adjusts logic in timerfd::read() to re-arm clock when clock jumps backwards to the same expiration time point which is still ahead of us. Signed-off-by: W

No worries. The time-related code has always been quite tricky to reason about:-) On Sunday, March 15, 2020 at 3:33:18 PM UTC-4, Nadav Har'El wrote: > > On Sun, Mar 15, 2020 at 9:25 PM Commit Bot > wrote: > >> From: Waldemar Kozaczuk > >> Committer: Waldemar Kozaczuk > >> Branch: master >> >> li

Re: [osv-dev] [PATCH] libc: make timerfd_* functions handle wall clock jumps

You might be right. But does it mean we can count on wake up mechanism to wake up up every _interval according to monotonic or real-time clock. I am honestly a bit at loss in my reasoning:-) On Sun, Mar 15, 2020 at 11:30 Nadav Har'El wrote: > On Fri, Mar 13, 2020 at 3:47 AM Waldemar Kozaczuk >

Changes since previous version: - Refactored the discovery of the shm regions, taking into account Waldek's input. I think this results in simpler code: the generic PCI code (drivers/pci-function.cc) returns the offsets of all capabilities of a given device and the virtio code (drivers/virtio
