Hello, I’m working on porting llvm to build for 65816, and I wanted to use a value of e_machine for this. I was wondering if there is a process for getting a value reserved. I’ve seen some information but its from many years ago, and seems to be well out of date? Just wanted to ask people who would likely know. -------------- next part -------------- An HTML attachment was scrubbed... URL:

While doing migration, sometimes found suspend lock file was not unlinked in previous operations, then there is an obsolete lock file in place, which causes the current and later migration cannot get lock. That happens seldomly but do happen. After checking the source code, I found there are some places that potentially cause lock file unlinked, including: 1) in lock_suspend_event() function,

Hello, I've got a very strange problem. Lately I've been setting up my linux servers for network (layer2) redundancy with a bridge interface containing two ethernet interfaces connecting to two switches. So far I didn't have any problems with it, but now a very strange thing happens with a new server I'm installing. The server is an ibm x346 having two onboard BCM5721 cards, the

When initializing XDP in virtnet_open(), some rq xdp initialization may hit an error causing net device open failed. However, previous rqs have already initialized XDP and enabled NAPI, which is not the expected behavior. Need to roll back the previous rq initialization to avoid leaks in error unwinding of init code. Also extract a helper function of disable queue pairs, and use newly introduced

We use single queue even if multiqueue is enabled and let admin to enable it through ethtool later. This is used to avoid possible regression (small packet TCP stream transmission). But looks like an overkill since: - single queue user can disable multiqueue when launching qemu - brings extra troubles for the management since it needs extra admin tool in guest to enable multiqueue - multiqueue

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, the second part of my work is to preserve the profiling information through all the transformation passes and make it available to the backend machinery. Attached is an example patch on how I plan to preserve the information for a given transformation pass. And now comes the question into place: whats the best way to attach the profile info

Commit 4490001029012539937ff02778fe6180613fa949 ("virtio-net: enable multiqueue by default") blindly set the affinity instead of queues during probe which can cause a mismatch of #queues between guest and host. This patch fixes it by setting queues. Reported-by: Theodore Ts'o <tytso at mit.edu> Tested-by: Theodore Ts'o <tytso at mit.edu> Cc: Neil Horman <nhorman

All, just having spotted the backport of Linux commit 03bbcb2e I notice a certain discrepancy with the Xen commit having the same purpose as well as with the actual specification updates: The Linux solution keys off of device IDs 3403 and 3406, as listed in the specification update, but this way fails to cover the X58 chipset, which has - under different numbers (62 and 69) - the same errata
