Strange regalloc behaviour: one more available register causes much worse allocation
...--------------- So there's two ways I can think of to fix this: * Make %381 be split in the same way that it is without the patch, which I think means deciding that there's only 1 bundle for w15. Does anyone know where and how exactly these bundles are decided? * Try and change how evicted / split registers are allocated in some way. Things I've tried: * In RAGreedy::enqueue reduce the score of unspillable local intervals, and in RAGreedy::evictInterference put evicted registers into stage RS_Split immediately. This causes %381 to be split immediately instead of bein...

1.6.4.1 - active client evicted
Hi! We''ve started to poke and prod at Lustre 1.6.4.1, and it seems to mostly work (we haven''t had it OOPS on us yet like the earlier 1.6-versions did). However, we had this weird incident where an active client (it was copying 4GB files and running ls at the time) got evicted by the MDS and all OST''s. After a while logs indicate that it did recover the connection to the MDT, but not the OST''s ... lctl ping between the client and mds/oss''s still worked. After a while I got tired of waiting for it to recover and did umount -f, which also hun...

newbie question about a dbuf-arc eviction race
Hi, Can a dbuf be in DB_CACHED state, db_holds == 0, b_efunc != NULL while its db_buf is put on the eviction list ? From an ASSERT in dbuf_do_evict(), it appears that it can. If it can, I am wondering what is preventing the following race dbuf_hold_impl() db = dbuf_find(dn, level, blkid); ... if (db->db_buf && refcount_is_zero(&db->db_holds)) {

Feature Concept: enable iCloud Drive with rsync
Hi, I have also posted this on GitHub but it isn?t clear that was the right place: https://github.com/WayneD/rsync/issues/522 iCloud Drive will evict files that are unused or when additional space is needed on the local drive. The evicted files are replace by "bookmark" files that allow MacOS to continue to report the files in the file system as though they were actually present. The files are downloaded again either on request or when needed. rsync, like all similar tools I can find, doesn't have any way of handling...

[Bug 1119] New: Hash code evicting other entries upon entry deletion (v6.25.1-v6.30)
...e set: it's not added" when deleting an entry that has not yet been legitimately deleted. The problem happens with a large number of entries; in some cases I've seen it with under 700 entries but typically it takes over 1,000 entries. I've seen one, two, even three or four entries evicted on a deletion. To reproduce the problem, do one of two things. You can use the data in the ipset tests directory (tests/iphash.t.large), or you can generate a fresh sequence. In the first case, do: ipset restore < tests/iphash.t.large In the second case, do: ipset create test hash:ip...

NV50: the tiled buffer object eviction problem
In short, we move out the low level content of a buffer object. In the case of textures and such this is utterly useless. Still it is accessed, because ttm sees no problem in using PL_SYSTEM or PL_TT memory. What is the best way to let ttm know we don't really appreciate that? A custom memory to evict to that cannot be mapped maybe. Or an extension of PL_SYSTEM or PL_TT. Share your ideas.

[PATCH] drm/nouveau: Evict buffers in VRAM before freeing sgdma
Currently, we take down the sgdma engine without evicting all buffers from VRAM. The TTM device release will try to evict anything in VRAM to GART memory, but this will fail since sgdma has already been taken down. This causes an infinite loop in kernel mode on module unload. It usually doesn't happen because there aren't any buffer on close. However, if the GPU is locked up, this

evicting clients when shutdown cleanly?
Should I be seeing messages like: Dec 14 12:06:59 nyx170 kernel: Lustre: MGS: haven''t heard from client dadccfac-8610-06e7-9c02-90e552694947 (at 141.212.30.185 at tcp) in 234 seconds. I think it''s dead, and I am evicting it. when the client was shut down cleanly? and the lustre file system is mounted via /etc/fstab ? The file system (i would hope) would be unmounted

Luster clients getting evicted
...all Gige and has about 608 nodes 1854 cores. We have allot of jobs that die, and/or go into high IO wait, strace shows processes stuck in fstat(). The big problem is (i think) I would like some feedback on it that of these 608 nodes 209 of them have in dmesg the string "This client was evicted by" Is this normal for clients to be dropped like this? Is there some tuning that needs to be done to the server to carry this many nodes out of the box? We are using default lustre install with Gige.

[LLVMdev] Poor register allocation (constants causing spilling)
...to keep the constant in a register for a single use! *** Live-Range Splitting Looking at the first constant, we can see that the copies are inserted by the greedy register allocator when it splits the live range. The main entry point is selectOrSplit. In brief: 1) The constant is assigned and evicted several times. Eventually selectOrSplit decides to split the live-range. This splits the interval in two, creating two new intervals (A and B). At the boundary of the intervals a copy is inserted that copies between the virtual registers. 2) The virtual register for the first interval (A) is as...

[PATCH nbdkit] file: Implement cache=none and fadvise=normal|random|sequential.
...and to get better behaviour with the page cache in some scenarios. For my testing I used the cachedel and cachestats utilities written by Julius Plenz (https://github.com/Feh/nocache). I started with a 32 GB file of random data on a machine with about 32 GB of RAM. At the beginning of the test I evicted the file from the page cache: $ cachedel /var/tmp/random $ cachestats /var/tmp/random pages in cache: 0/8388608 (0.0%) [filesize=33554432.0K, pagesize=4K] Performing a normal sequential copy of the file to /dev/null shows that the file is almost entirely pulled into page cache (thus evicting use...
