* SUNRPC: Remove duplicate universal address generationChuck Lever2009-08-094-46/+29
| | | | | | | | | | | | | | | | | | | | RPC universal address generation is currently done in several places: rpcb_clnt.c, nfs4proc.c xprtsock.c, and xprtrdma.c. Remove the redundant cases that convert a socket address to a universal address. The nfs4proc.c case takes a pre-formatted presentation address string, not a socket address, so we'll leave that one. Because the new uaddr constructor uses the recently introduced rpc_ntop(), it now supports proper "::" shorthanding for IPv6 addresses. This allows the kernel to register properly formed universal addresses with the local rpcbind service, in _all_ cases. The kernel can now also send properly formed universal addresses in RPCB_GETADDR requests, and support link-local properly when encoding and decoding IPv6 addresses.

* SUNRPC: Provide functions for managing universal addressesChuck Lever2009-08-094-3/+403
| | | | | | | | | | | | | | | | | | | | | | | Introduce a set of functions in the kernel's RPC implementation for converting between a socket address and either a standard presentation address string or an RPC universal address. The universal address functions will be used to encode and decode RPCB_FOO and NFSv4 SETCLIENTID arguments. The other functions are part of a previous promise to deliver shared functions that can be used by upper-layer protocols to display and manipulate IP addresses. The kernel's current address printf formatters were designed specifically for kernel to user-space APIs that require a particular string format for socket addresses, thus are somewhat limited for the purposes of sunrpc.ko. The formatter for IPv6 addresses, %pI6, does not support short-handing or scope IDs. Also, these printf formatters are unique per address family, so a separate formatter string is required for printing AF_INET and AF_INET6 addresses.

* NFS: Use the authentication flavor list returned by mountdChuck Lever2009-08-091-7/+51
| | | | | | | | | | | | | | | | | | | | Commit a14017db added support in the kernel's NFS mount client to decode the authentication flavor list returned by mountd. The NFS client can now use this list to determine whether the authentication flavor requested by the user is actually supported by the server. Note we don't actually negotiate the security flavor if none was specified by the user. Instead, we try to use AUTH_SYS, and fail if the server does not support it. This prevents us from negotiating an inappropriate security flavor (some servers list AUTH_NULL first). If the server does not support AUTH_SYS, the user must provide an appropriate security flavor by specifying the "sec=" mount option.

* NFS: Fix auth flavor len accountingChuck Lever2009-08-091-14/+3
| | | | | | | | | | | | | | | | | | | | | | | Previous logic in the NFS mount parsing code path assumed auth_flavor_len was set to zero for simple authentication flavors (like AUTH_UNIX), and 1 for compound flavors (like AUTH_GSS). At some earlier point (maybe even before the option parsers were merged?) specific checks for auth_flavor_len being zero were removed from the functions that validate the mount option that sets the mount point's authentication flavor. Since we are populating an array for authentication flavors, the auth_flavor_len should always be set to the number of flavors. Let's eliminate some cleverness here, and prepare for new logic that needs to know the number of flavors in the auth_flavors[] array. (auth_flavors[] is an array because at some point we want to allow a list of acceptable authentication flavors to be specified via the sec= mount option. For now it remains a single element array).

* NFS: Add ability to send MOUNTPROC_UMNT to the kernel's mountd clientChuck Lever2009-08-092-0/+80
| | | | | | | | | | | | | | | After certain failure modes of an NFS mount, an NFS client should send a MOUNTPROC_UMNT request to remove the just-added mount entry from the server's mount table. While no-one should rely on the accuracy of the server's mount table, sending a UMNT is simply being a good internet neighbor. Since NFS mount processing is handled in the kernel now, we will need a function in the kernel's mountd client that can post a MOUNTRPC_UMNT request, in order to handle these failure modes.

* NFS: Fix up new minorversion= optionChuck Lever2009-08-091-7/+11
| | | | | | | | | | | | The new minorversion= mount option (commit 3fd5be9e) was merged at the same time as the recent sloppy parser fixes (commit a5a16bae), so minorversion= still uses the old value parsing logic. If the minorversion= option specifies a bogus value, it should fail with "bad value" not "bad option."

| * 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).

| * | drm/I915: Fix offset to DVO timings in LVDS dataZhao Yakui2009-07-291-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now the DVO timing in LVDS data entry is obtained by using the following step: a. get the entry size for every LVDS panel data b. 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you're pushing a plane hard (i.e. you need most or all of the FIFO entries just to cover your frame refresh latency), the watermark level may end up being negative. So fix up the signed vs. unsigned math in the calculation function to handle this correctly, giving all available FIFO entries to such a configuration.

| * | drm/i915: FIFO watermark calculation fixesJesse Barnes2009-07-142-75/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I discovered several bugs in the FIFO code that was recently applied. Some of them fell into the "how did this ever work" category, since in some cases we were using the wrong FIFO size values, and the calculations ended up being way off. This patch fixes all the bugs I found, and works well on my GM45, 915GM and 855GM test machines; but as usual with these sorts of patches broader testing is definitely requested (in particular this patch affects 830, 845 and 865 for which I don't have test hardware). Overall, the patch clarifies the watermark calculation function by adding some comments and debug info, and making the variable names a bit clearer. The "get FIFO size" portion of the code has also been corrected, so we should be able to properly detect the FIFO allocations for each pipe, for use in the watermark calculation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 915 and 945 scanout engines can handle frame buffers up to 4096 pixels wide. Pre-9xx hardware has an 8192 byte stride limit, and so we leave the existing 2048 max in place. I'm not sure why we limit the height to the same value; there's no intrinsic hardware limit in the scanout engine.
