* SUNRPC: Remove the global temporary write buffer in net/sunrpc/cache.cTrond Myklebust2009-08-091-25/+70
| | | | | | | | | | | | | | | | | While we do want to protect against multiple concurrent readers and writers on each upcall/downcall pipe, we don't want to limit concurrent reading and writing to separate caches. This patch therefore replaces the static buffer 'write_buf', which can only be used by one writer at a time, with use of the page cache as the temporary buffer for downcalls. We still fall back to using the the old global buffer if the downcall is larger than PAGE_CACHE_SIZE, since this is apparently needed by the SPKM security context initialisation. It then replaces the use of the global 'queue_io_mutex' with the inode->i_mutex in cache_read() and cache_write(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* SUNRPC: One more clean up for rpc_create_client_dir()Trond Myklebust2009-08-091-28/+50
| | | | | | | | | | | In order to allow rpc_pipefs to create directories with different types of subtrees, it is useful to allow the caller to customise the subtree filling process. In order to do so, we separate out the parts which are specific to making an RPC client directory, and put them in a separate helper, then we convert the process of filling the directory contents into a callback.

* SUNRPC: clean up rpc_setup_pipedir()Trond Myklebust2009-08-094-72/+37
| | | | | | | | | | | | There is still a little wart or two there: Since we've already got a vfsmount, we might as well pass that in to rpc_create_client_dir. Another point is that if we open code __rpc_lookup_path() here, then we can avoid looking up the entire parent directory path over and over again: it doesn't change. Also get rid of rpc_clnt->cl_pathname, since it has no users... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

| * USB: EHCI: fix two new bugs related to Clear-TT-BufferAlan Stern2009-08-072-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1273) fixes two(!) bugs introduced by the new Clear-TT-Buffer implementation in ehci-hcd. It is now possible for an idle QH to have some URBs on its queue -- this will happen if a Clear-TT-Buffer is pending for the QH's endpoint. Consequently we should not issue a warning when someone tries to unlink an URB from an idle QH; instead we should process the request immediately. The refcounts for QHs could get messed up, because submit_async() would increment the refcount when calling qh_link_async() and qh_link_async() would then refuse to link the QH into the schedule if a Clear-TT-Buffer was pending. Instead we should increment the refcount only when the QH actually is added to the schedule. The current code tries to be clever by leaving the refcount alone if an unlink is immediately followed by a relink; the patch changes this to an unconditional decrement and increment (although they occur in the opposite order).

Scott was kind enough to test a few patches and report success with this one. Looks like 845G measures FIFO size slightly differently than other chips, and we were also clobbering the FIFO burst length. Fixing both of those issues gives him a healthy machine again. Note that we still only adjust plane A's watermark in the 830/845 case. If someone is willing to test we could support a bigger variety of dual-head 830/845 configurations with a bit more code.

Get the LVDS fp entry for the preferred panel type c. get the DVO timing by using entry->dvo_timing In our driver the entry->dvo_timing is related with the size of lvds_fp_timing. For example: the size is 46. But it seems that the size of lvds_fp_timing varies on the differnt platform. In such case we will get the incorrect DVO timing entry because of the incorrect DVO offset in LVDS panel data entry. This also removes a hack on new IGDNG to get proper DVO timing. Calculate the DVO timing offset in LVDS data entry to get the DVO timing a. get the DVO timing offset in the LVDS fp data entry by using the pointer definition in LVDS data ptr b. get the LVDS data entry c. get the DVO timing by adding the DVO timing offset to data entry https://bugs.freedesktop.org/show_bug.cgi?id=22787 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Tested-by: Zhenyu Wang <zhenyuw@linux.intel.com> Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>
| * | drm/i915: hdmi detection according by reading edidling.ma@intel.com2009-07-221-60/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to investigations from windows team ,hw team, and our test results on all 4x platofrms available (gm45, g45b, q45, g45a, g45c, g41a, and g41), we find currently Hot plug live status and Hot plug interrupt detection are not reliable, sometime the results from the two approaches are contradicts. So we chose edid detection for hdmi output. Signed-off-by: Ma Ling <ling.ma@intel.com> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
| * | drm/i915: correct self-refresh calculation in "everything off" caseJesse Barnes2009-07-161-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If no planes are enabled, the self-refresh calculation may end up doing a divide by zero. This patch should prevent that by making sure at least one of the CRTCs had a valid hdisplay value.
