2009-10-28drm/radeon/kms/atom: Fix DVO supportAlex Deucher
DVO in 12 bit mode (which seems to be the most common config) requires 2x ppll. Fixes fdo bug 21857. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-10-28drm/radeon/kms/atom: loosen pll min output limitsAlex Deucher
Limiting the pll output range is a good thing generally as it limits the number of possible pll combinations for a given frequency presumably to the ones that work best on each card. That's why the limits are in the bios tables. However, certain duallink DVI monitors seem to like pll combinations that would be limited by this at least on pre-DCE 3.0 r6xx hardware. This might need to be adjusted per family or per clock range in the future. See fdo bug 24727. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-10-28drm/kms: fix kms/fbdev colormap support properly.Dave Airlie
This sets the fbcon to use TRUECOLOR by default, it then only modifies the pseudo palette for fbcon, and only touches the real palette when in 8-bit pseudo color mode. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-10-28drm: Add the basic check for the detailed timing in EDIDZhao Yakui
Sometimes we will get the incorrect display modeline when parsing the detailed timing in EDID. For example: >hsync/vsync width is zero >sync is beyond the blank. So add the basic check for the detailed timing in EDID to avoid the incorrect display modeline. Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-10-28drm/radeon/kms: ignore vga arbiter return.Dave Airlie
Since we register all radeon devices, and the arbiter only cares about VGA class ones, we will fail to startup on display controller class devices.

2009-10-27mac80211: fix for incorrect sequence number on hostapd injected framesBjörn Smedman
When hostapd injects a frame, e.g. an authentication or association response, mac80211 looks for a suitable access point virtual interface to associate the frame with based on its source address. This makes it possible e.g. to correctly assign sequence numbers to the frames. A small typo in the ethernet address comparison statement caused a failure to find a suitable ap interface. Sequence numbers on such frames where therefore left unassigned causing some clients (especially windows-based 11b/g clients) to reject them and fail to authenticate or associate with the access point. This patch fixes the typo in the address comparison statement.

2009-10-27mac80211: fix ibss joiningReinette Chatre
Recent commit "mac80211: fix logic error ibss merge bssid check" fixed joining of ibss cell when static bssid is provided. In this case ifibss->bssid is set before the cell is joined and comparing that address to a bss should thus always succeed. Unfortunately this change broke the other case of joining a ibss cell without providing a static bssid where the value of ifibss->bssid is not set before the cell is joined. Since ifibss->bssid may be set before or after joining the cell we do not learn anything by comparing it to a known bss. Remove this check.

2009-10-27b43: Fix Bugzilla #14181 and the bug from the previous 'fix'Larry Finger
"b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported in Bugzilla No. 14181; however, it introduced a new bug. Whenever the radio switch was turned off, it was necessary to unload and reload the driver for it to recognize the switch again. This patch fixes both the original bug in #14181 and the bug introduced by the previous patch. It must be stated, however, that if there is a BCM4306/3 with an rfkill switch (not yet proven), then the driver will need an unload/reload cycle to turn the device back on.

2009-10-27powerpc/ppc64: Use preempt_schedule_irq instead of preempt_scheduleBenjamin Herrenschmidt
Based on an original patch by Valentine Barshak <vbarshak@ru.mvista.com> Use preempt_schedule_irq to prevent infinite irq-entry and eventual stack overflow problems with fast-paced IRQ sources. This kind of problems has been observed on the PASemi Electra IDE controller. We have to make sure we are soft-disabled before calling preempt_schedule_irq and hard disable interrupts after that to avoid unrecoverable exceptions. This patch also moves the "clrrdi r9,r1,THREAD_SHIFT" out of the #ifdef CONFIG_PPC_BOOK3E scope, since r9 is clobbered and has to be restored in both cases.

2009-10-26PPPoE: Fix flush/close races.Michal Ostrowski
Be more careful about the state of pointers during tear-down. The "pppoe_dev" field can only be looked at safely while holding socket locks. This subsequently allows for the flush_lock to be killed. We depend on the PPPOX_CONNECTED state to tell us that that those fields are valid, so whoever clears that state (pppox_unbind_sock()) is responsible for the dev_put() call. We also have to ensure that we delete_item() on all sockets before they are cleaned up. The need for these changes has been exposed by scenarios wherein namespace bindings of ethernet devices change while there are ongoing PPPoE sessions, which resulted in oopses due to unusual socket connection termination paths, exposing these issues.

2009-10-26e1000e: allow for swflag to be held over consecutive PHY accessesBruce Allan
PCH-based parts (82577/82578) and some ICH8-based parts (82566) need to hold the swflag (sw/fw/hw hardware semaphore) over consecutive PHY accesses in order to perform sw-driven PHY configuration during initialization to workaround known hardware issues (see follow-on patch). This patch provides new PHY read/write functions (and function pointers) that will allow accessing the PHY registers assuming the swflag has already been acquired. The actual PHY register access code has moved into helper functions that are called with a flag indicating whether or not the swflag has already been acquired and acquires/releases it if not. The functions called from within the updated PHY access functions had to be updated to assume the swflag was already acquired, and other functions that called those functions were also updated to acquire/release the swflag.

2009-10-26e1000e: separate mutex usage between NVM and PHY/CSR register for ICHx/PCHBruce Allan
Accesses to NVM and PHY/CSR registers on ICHx/PCH-based parts are protected from concurrent accesses with a mutex that is acquired when the access is initiated and released when the access has completed. However, the two types of accesses should not be protected by the same mutex because the driver may have to access the NVM while already holding the mutex over several consecutive PHY/CSR accesses which would result in livelock.

2009-10-26e1000e: increase swflag acquisition timeout for ICHx/PCHBruce Allan
In some conditions (e.g. when AMT is enabled on the system), it is possible to take an extended period of time to for the driver to acquire the sw/fw/hw hardware semaphore used to protect against concurrent access of a shared resource (e.g. PHY registers). This could cause PHY registers to not get configured properly resulting in link issues.

2009-10-26igb: fix memory leak when setting ring size while interface is downAlexander Duyck
Changing ring sizes while the interface was down was causing a double allocation of the receive and transmit rings. This issue is amplified when there are multiple rings enabled. To prevent this we need to add an additional check which will just update the ring counts when the interface is not up and skip the allocation steps.
