Hi, my laptop has muted sound after resuming the soundcard (by s2ram/hibernation). The problem seems to be that the cached register values are not written back to the device properly. Before suspend, the registers look like this: 0:00 = 1990 0:02 = 0000 0:04 = 9f1f 0:06 = 801f 0:08 = 0000 0:0a = 801e 0:0c = 801f 0:0e = 801f 0:10 = 9f1f 0:12 = 9f1f 0:14 = 9f1f 0:16 = 9f1f 0:18 = 0b0b 0:1a = 0000 0:1c = 0000 0:1e = 0000 0:20 = 0000 0:22 = 0000 0:24 = 0000 0:26 = 000f 0:28 = 020...

From: Cliff Wickman <cpw@sgi.com> TLB shootdown for SGI UV. This patch provides the ability to flush TLB's in cpu's that are not on the local node. The hardware mechanism for distributing the flush messages is the UV's "broadcast assist unit". The hook to intercept TLB shootdown requests is a 2-line change to native_flush_tlb_others() (arch/x86/kernel/tlb_64.c). This code has been tested on a hardware simulator. The real hardware is not yet available. The shootdown statistics a...

The POSIX.1 draft spec for utimensat() says that to do anything other than setting both timestamps to a time other than the current time (i.e., times is not NULL, and both tv_nsec fields are not UTIME_NOW and both tv_nsec fields are not UTIME_OMIT), either: a) the caller's effective user ID must match the file owner; or b) the caller must have appropriate privileges. If this condition is violated, then the error EPERM should result. However, the current implementation does not generate EPERM if ...

The POSIX.1 draft spec for utimensat() says that if a times[n].tv_nsec field is UTIME_OMIT or UTIME_NOW, then the value in the corresponding tv_sec field is ignored. However the current Linux implementation requires the tv_sec value to be zero (or the EINVAL error results). This requirement should be removed.

Yes! It does. Dimitri Sivanich has run into what looks like a similar problem. Hope the above workaround is a good clue to its solution. -- Cliff Wickman Silicon Graphics, Inc. cpw@sgi.com (651) 683-3824 --

David, What tree should be used for this patch? On wireless-testing that git-describe lists as v2.6.26-rc4-8782-gd9a8bd7, hunk 5 for mlme.c fails. Larry --

Awesome stuff. With respect to wpa supplicant, I'd expect we need some sort of handling for this wrt. notifications (multicast) which is a bit Did you miss drivers/net/ps3_gelic_wireless.c? johannes

From: David Miller <davem@davemloft.net> Here is a respin of patch 12 with the ps3 bits included, thank for noticing Johannes. I've also respun the tree on kernel.org so that it's fixed there too. wext: Emit event stream entries correctly when compat. Three major portions to this change: 1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF, and IW_EV_COMPAT_POINT_LEN helper defines. 2) Delete iw_stream_check_add_*(), they are unused. 3) Add iw_request_info argument to iwe_str...

This is a refresh of my previous WEXT compat patch set. I've actually tested these exact patches on sparc64 with a RNDIS based USB wireless device from Linksys. I was able to perform iwconfig commands, check iwlist, bring up the interface and use it properly. All with 32-bit tools. I've also done an allmodconfig sanity build check on sparc64. The one thing I was not able to test yet is wpa_supplicant use, and that likely doesn't work properly yet, but we can fix that on top and these patches...

Next we can kill the hacks in fs/compat_ioctl.c and also dispatch compat ioctls down into the driver and 80211 protocol helper layers in order to handle iw_point objects embedded in stream replies which need to be translated.

Andrew, The following is why I think my patch should preferably be applied for 2.6.26, rather than waiting for .27. The first reason is the obvious. The test suite runs 99 tests. With my patch applied to 2.6.24-rc4, all tests pass (see the attached test results). There is another reason why I think we should apply the patch for .26. On 2.6.25, we have: Total tests: 99; passed: 73; failed: 26 On 2.6.26-rc4, we have: Total tests: 99; passed: 74; failed: 25 As far as I can see, thi...

Andrew, This patch fixes all of the utimensat() bugs outlined in my previous mail. I could have split the patch out into a few pieces, but given that it is not long, and all against a single file, I've made one patch. Let me know if you would like separate patches for the pieces below. Miklos suggested an alternative idea, migrating the is_owner_or_cap() check into fs/attr.c:inode_change_ok() via the use of an ATTR_OWNER_CHECK flag. Maybe we could do that later, but for now I've one with t...
