Re: radeon_cp_texture: page fault with non-sleepable locks held
on 09/11/2010 16:05 Kostik Belousov said the following: > Easiest would be for DRM to provide wrappers for copyin/copyout that > unlock, do operation and lock. I am a little bit worried about this approach in general. Driver state may be changed by a process running in parallel while the lock is dropped. And I don't think that we have any mechanism in DRM to check for that and to restart operations or otherwise account for the state change. The code seems to be written with an assumption that it runs in exclusive mode from DRM ioctl start to its completion. > Where is the reverse order (user map -> drm) ?

Whatever... people are going to gripe either way with this change, so I guess making people think is more important than misleading them into thinking things work. It's just easier to slap someone on the hand if they hit ACPI, and less annoying for automated expect scripts because they don't have to hit a different number, but I suppose if they were smart they would use the loader prompt anyhow instead of the menu *shrugs*. So, this is a "I understand, slap me on the hand if I hit 4 or 6" agreement :).

Wait a minute. The menu is a POLA violation. I'm used to hitting 'boot -s' and entering just '4' is clearly not the way the Lord meant it to be. (I edit the loader.4th file to turn it off o my personal systems, being an old curmudgeon.) If you are going to use a menu at all, why not make it as functional as possible?

Could anyone who knows, pipe upt and let use know what the factors are, and if the current limit is overcome, what the next one after that will be? You mean beyond architectural limits? no, though of course they are relevant. I was thinking more of details like limits to the KVM space or any limitations there may be on the size of the direct-map region, or maybe some limit on some data structure size in the kernel. Since I don 't know the details, this is exactly the question.. what IS the limit? The changes to support more than 512GB RAM should be straightforward. Off the top of my head, it will require some constant definitions in vmparam.h to change, and the allocation of some additional PDP-level page table pages in create_pagetables(). In contrast, the changes to break the original 2GB KVM barrier involved touching a number of different places in the kernel. Alan, since some people (e.g. Sean Bruno) were hitting this, do you think you could provide a patch to allow people to test this? Sean in Particular seemed keen to try go to 1TB ram in a machine he had access to.

Since I don 't know the details, this is exactly the question.. what IS the limit? The changes to support more than 512GB RAM should be straightforward. Off the top of my head, it will require some constant definitions in vmparam.h to change, and the allocation of some additional PDP-level page table pages in create_pagetables(). In contrast, the changes to break the original 2GB KVM barrier involved touching a number of different places in the kernel.

It is really not robust. Copy-pasting is also broken because of it, because it pastes CP437 characters. > The only thing i cannot do here is to type chars with accent like áé > on console, because it seems to don't respect deadkeys, when I > press ' the char ' is show and never wait the next char to compose > a new one when necessary. Is it a knwon issue or i'm doing > something wrong? This is a known issue, since there is no translation from Unicode code points to UTF-8 sequences. In other words, if you press ë, the keyboard layer will properly send a 235 to Syscons, but instead of encoding it as 0xC3 0xA9, will just emit a single byte, having value 0xE9. Maybe a patch like this could already get that working, but it's just a quick hack. http://80386.nl/pub/syscons-utf8.txt Greetings, -- Ed Schouten WWW: http://80386.nl/ pgpDFXZrgCmH7.pgp Description: PGP signature

What else could I debug to nail this down?

I am not entirely sure about style in which I handled handling of version 1 minidump. Identifier names like pmapsize (for "page map size") and page_map could also be improved, perhaps. 2. kernel - implemented dumping of 1GB pages via "fake" 512 x 2MB pages per Alan's suggestion. The change is only compile tested so far. Not sure if it's possible to test handling 1GB pages yet :-) As always, reviews, testing and suggestions are very welcome. The kernel portion of the patch looks correct. If I were to make one stylistic suggestion, it would be to make the control flow of the outer and inner loops as similar as possible, that is, for (... if ((pdp[i] & PG_V) == 0) { ... continue; } if ((pdp[i] & PG_PS) != 0) { ... continue; } for (... if ((pd[j] & PG_V) == 0) continue; if ((pd[j] & PG_PS) != 0) { ... continue; } for (... if ((pt[x] & PG_V) == 0) continue; ...

That's also an appreciated improvement, but what PCBSD does is that you can toggle several options, so when you select an option, the kernel is not loaded immediately after but you are still in the menu and can select / toggle another option. That way you have a multi-selection, e.g. select safe mode but enable acpi. Maybe we could also add a menu entry to boot without any modules, so loaders.conf gets overridden? pgpNyR4N1wYaD.pgp Description: PGP signature

Did you get an error message in dmesg? If you have manually loaded netgraph.ko (via netgraph_load="YES" in loader.conf or an explicit kldload) and then loaded other modules that depend on it (such as ng_foo.ko) then this is expected behavior. What your kldunload has done is to remove the manual reference from loader.conf or 'kldload netgraph.ko'. What this changes is what happens when you do 'kldunload ng_foo.ko'. If you unload ng_foo.ko now, then netgraph.ko will also be unloaded when its last reference drops (in this case it looks like you actually have two ng_*.ko objects loaded, so you would have to unload both of them, but I will assume a single ng_foo.ko to make the explanation simpler). If you had not done 'kldunload netgraph.ko' but had done 'kldunload ng_foo.ko', then the manual reference would have kept netgraph.ko loaded. All this logic exists so that if you do 'kldload foo.ko' and it auto-loads bar.ko as a dependency, then doing 'kldunload bar.ko' will unload both foo.ko and bar.ko. -- John Baldwin ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

hi there, i posted this message on freebsd-questions@, but nobody could help me with it. to me this looks like a bug, so i assume posting it again here on freebsd-current@ might be better. please keep in mind that the issue here is not the fact that the second attempt to unload sound.ko/netgraph.ko fails. it *should* fail, because both modules have dependencies. however it should fail with the first attempt. right now kldunloadf() returns zero, whereas it should actually return EBUSY (just like the second attempt). i've attached two kdump outputs: one for the first 'kldunload' attempt and one for the second. as you can see the problem is that for some reason kldunloadf() returns zero, although it couldn't unload the module. cheers. alex - Forwarded message from Alexander Best - Date: Fri, 5 Nov 2010 01:15:24 + From: Alexander Best To: freebsd-questi...@freebsd.org Subject: Re: kldunload(8) returns 0, although it fail On Wed Nov 3 10, Alexander Best wrote: > hi there, > > is this a known issue with kldunload(8)? this is also very interesting: ***beginn*** otaku% kldstat -v|grep netgraph 73 0x80bfa000 15e68netgraph.ko (/boot/kernel/netgraph.ko) 6 netgraph otaku% sudo kldunload netgraph otaku% echo $? 0 otaku% kldstat -v|grep netgraph 72 0x80bfa000 15e68netgraph.ko (/boot/kernel/netgraph.ko) 6 netgraph otaku% ***end*** there seems to be a logical error in the ref counting code. cheers. alex > > ***beginn*** > otaku% kldunload sound > otaku% echo $? > 0 > otaku% kldstat > Id Refs AddressSize Name > 1 35 0x8010 a2da40 kernel > 21 0x80b2e000 295e8snd_hda.ko > 31 0x80b58000 85110sound.ko > 41 0x80bde000 da4bb8 nvidia.ko > 54 0x81983000 418e0linux.ko > 61 0x819c5000 80e8 ng_ubt.ko > 72 0x819ce000 fa78 ng_hci.ko > 82 0x819de000 2bd0 ng_bluetooth.ko > 93 0x819e1000 15e68netgraph.ko > 101 0x81c12000 3edb linprocfs.ko > 113 0x81c16000 4698 pseudofs.ko > 121 0x81c1b000 31b3 procfs.ko > 131 0x81c1f000 a37 linsysfs.ko > otaku% kldunload sound > kldunload: attempt to unload file that was loaded by the kernel > kldunload: can't unload file: Device busy > otaku% echo $? > 1 > otaku% > ***end*** > > cheers. > alex > > -- > a13x -- a13x - End forwarded message - -- a13x 1765 ktrace RET ktrace 0 1765 ktrace CALL execve(0x7fffe580,0x7fffeb00,0x7fffeb18) 1765 ktrace NAMI "/sbin/kldunload" 1765 ktrace NAMI "/libexec/ld-elf.so.1" 1765 kldunload RET execve 0 1765 kldunload CALL mmap(0,0x8000,0x3,0x1002,0x,0) 1765 kldunload RET mmap 34365239296/0x80053f000 1765 kldunload CALL issetugid 1765 kldunload RET issetugid 0 1765 kldunload CALL open(0x80053a8b2,0,0x1b6) 1765 kldunload NAMI "/etc/libmap.conf" 1765 kldunload RET open 3 1765 kldunload CALL fstat(0x3,0x7fffdc10) 1765 kldunload STRU struct stat {dev=98, ino=5841236, mode=-rw-r--r-- , nlink=1, uid=0, gid=0, rdev=23396840, atime=1289300105, stime=1285331572, ctime=1285331572, birthtime=1268953179, size=235, blksize=16384, blocks=4, flags=0x0 } 1765 kldunload RET fstat 0 1765 kldunload CALL read(0x3,0x800542000,0x4000) 1765 kldunload GIO fd 3 read 235 bytes "#libgcc_s.so.1 gcc46/libgcc_s.so.1 #libgomp.so.1 gcc46/libgomp.so.1 #libssp.so.0gcc46/libssp.so.0 #libstdc++.so.6 gcc46/libstdc++.so.6 #libz.so.5 libz.so.6 #libmd.so.5 libmd.so.1.0 #libmd.so.5 libcrypto.so #libmd.so.5 libmd-test.so.5 " 1765 kldunload RET read 235/0xeb 1765 kldunload CALL read(0x3,0x800542000,0x4000) 1765 kldunload GIO fd 3 read 0 bytes "" 1765 kldunload RET read 0 1765 kldunload CALL close(0x3) 1765 kldunload RET close 0 1765 kldunload CALL open(0x800539a49,0,0x2f) 1765 kldunload NAMI "/var/run/ld-elf.so.hints" 1765 kldunload RET open 3 1765 kldunload CALL read(0x3,0x7fffe220,0x80) 1765 kldunload GIO fd 3 read 128 bytes 0x 4568 6e74 0100 8000 db00 da00 |Ehnt| 0x0048 || 1765 kldunload RET read 128/0x80 1765 kldunload CALL mmap(0,0x9000,0x3,0x1002,0x,0) 1765 kldunload RET mmap 34365272064/0x800547000 1765 kldunload CALL lseek(0x3,0x80,SEEK_SET)

Yes, but not only must you set TERM=xterm, you must also remove TEKEN_CONS25 from your kernel configuration or run vidcontrol -T xterm on that specific window. There is almost no reason why anyone would want to use the TEKEN_CONS25 option. Depending on whether the terminal is switched to cursor keys mode, it will return ^[[H or ^[OH.

Kostik, I looked at this some more and now I think that using sx is a step in the right direction. Rationale: 1. it seems that on Linux mutex is a sleepable lock and thus can be safely held across a page fault; and Linux mutex -> FreeBSD sx seems to be a porting technique used for kernel code before[*]. 2. DRM interrupt code uses a different lock - irq_lock, which is locked via DRM_SPINLOCK macro (expands to FreeBSD mutex); apparently even on Linux a sleep-able lock can't be acquired in interrupt handler. I use Linux this and Linux that as a justification, because the DRM code apparently originated with Linux model/idioms in mind, although the original purpose was for the code to be portable. So, what do you think about this aspect? Should you agree with the usage of sx, then the previous question pops back - how to resolve the lock order reversal between drmdev lock and user map lock (which both would be sx).
