commit 55aa42f2 upstream. The dmi_list array is initialized using gnu designated initializers, and therefore may contain fewer explicitly defined entries as there are elements in it. This is because the enum above with M_xyz constants contains more items than the designated initializer. Those elements not explicitly initialized are implicitly set to 0. Now efifb_setup() loops through all these array elements, and performs a strcmp on each item. For non explicitly initialized elements this will be a null pointer: This patch swaps the check order in the if statement, thus checks first whether dmi_list[i].base is null. Signed-off-by:

commit a404d557 upstream. Currently each task sends BLK_TN_PROCESS event to the first traced device it interacts with after a new trace is started. When there are several traced devices and the task accesses more devices, this logic can result in BLK_TN_PROCESS being sent several times to some devices while it is never sent to other devices. Thus blkparse doesn't display command name when parsing some blktrace files. Fix the problem by sending BLK_TN_PROCESS event to all traced devices when a task interacts with any of them.

commit 22b4f0cd upstream. This patch abstracts out a AMD chipset type which includes southbridge generation and its revision. When os excutes usb_amd_find_chipset_info routine to initialize AMD chipset type, driver will know which kind of chipset is used. This update has below benifits: - Driver is able to confirm which southbridge generations and their revision are used, with chipset detection once. - To describe chipset generations with enumeration types brings better readability. - It's flexible to filter AMD platforms to implement new quirks in future.

commit efe47108 upstream. There is a small gap between the jack detection unsolicited event and the time the ELD is updated. When user-space queries the HDMI ELD immediately after receiving the notification, it might fail because of this gap. For avoiding such a problem, this patch tries to delay the HDMI jack detect notification until ELD information is fully updated. The workaround is imperfect, but good enough as a starting point.

commit bbaa0d66 upstream. The device IDs of the AMD Cypress/Juniper/Redwood/Cedar/Cayman/Antilles/ Barts/Turks/Caicos HDMI HDA controllers weren't added explicitly because the generic entry works, but it made the device appearing as "Generic", and people are confused as if it's no proper HDMI controller. Add them so that the name shows up properly as "ATI HDMI" instead of "Generic". According to Takashi's tests and the lack of complaints, these devices work fine without disabling snooping.

commit 02383854 upstream. For Valleyview display codec, if an unused pin chooses an assgined converter selected by a used pin, playback on the unused pin can also give sound to the output device of the used pin. It's because data flows from the same convertor to the display port of the used pin. This issue is same as Haswell. So this patch avoids using assinged convertors for unused pins. The related function haswell_config_cvts() is renamed for code reuse. Signed-off-by:

commit a4e9a38b upstream. Since the lock is used primarily in patch_hdmi.c, it's better to move it in the local struct instead of exporting in hda_eld. The only functions requiring the lock in hda_eld.c are proc accessors. So in this patch, the proc entry and its creation/deletion/accessors are moved into patch_hdmi.c, together with the mutex lock to pin_spec struct. The former proc info functions are exported so that they can be called from patch_hdmi.c. Signed-off-by:

commit bb731f21 upstream. Currently the available channel maps TLV only contains channel maps that are limited to the traditional 7.1 speakers. Since the other HDMI channel mapping functions have been fixed to properly handle all CEA-861-E specified speakers, allow them to be listed. Signed-off-by:

commit a5b7d510 upstream. For some speakers and slots the CEA slot <-> speaker assignment depends on the used CEA Channel Allocation value. Therefore the from_cea_slot() and to_cea_slot() helpers currently only work correctly for the regular 7.1 speakers. Fix them to work with all speakers, taking the re-ordered CA index as input and adapting use sites accordingly. This change allows manual channel mapping to actually work for all CEA allocated speakers. Additionally, this fixes incorrect channel map reporting in automatic channel mapping mode when an affected speaker position is used (e.g. 6.1 map which contains an RC speaker). Signed-off-by:

commit 11f7c52d upstream. hdmi_manual_setup_channel_mapping() and hdmi_std_setup_channel_mapping try to assign ALSA channels to HDMI channel slots and disable (i.e. silence) other slots. However, they try to disable a slot by using AC_VERB_SET_CHAN_SLOT with parameter ((alsa_ch << 8) | 0xf), while the correct parameter is ((0xf << 8) | hdmi_slot), i.e. the slot should be unassigned, not the ALSA channel. Fix that by actually disabling the unused slots. Note that this bug did not cause any (reported) issues because slots incorrectly having audio are normally ignored by a receiver if the CEA channel allocation used does not map that slot to any speaker. Additionally, the converter channel count configuration limits the number of actually active channels in any case. Signed-off-by:

Anssi Hannula authored
commit 1df5a06a upstream. Currently the converter channel count is set to the number of actual input channels. The audio infoframe channel count field is set similarly. However, sometimes the used channel map does not map all input channels to outputs. Notably, 3 channel modes (e.g. 2.1) require a dummy input channel so there are 4 input channels. According to the HDA specification, converter channel count should be programmed according to the number of _active_ channels. On Intel HDMI codecs (but not on NVIDIA), setting the converter channel to a higher value than there are actually mapped channels to HDMI slots will cause no audio to be output at all. Note that the effects of this issue are currently partially masked by other bugs that prevent the driver from actually unmapping channels in certain cases. For example, if a 4 channel stream is first created and prepared, it gets a FL,FR,RL,RR mapping (ALSA->HDMI slot mapping 0->0, 1->1, 2->4, 3->5). If one thereafter assigns a FR,FL,FC mapping to it, the driver will remap 2->3 but fail to unmap 2->4 and 3->5, so there are still 4 active channels and the issue will not trigger in this case. These bugs will be fixed separately. Fix the channel counts in the converter channel count field and in the audio infoframe channel count field to match the actual number of active channels.

commit 90f28002 upstream. hdmi_std_setup_channel_mapping() selects a Channel Allocation according to the sink reported speaker mask, preferring the ALSA standard layouts. If the channel allocation is not one of the ALSA standard layouts, the ALSA channels are mapped directly to HDMI channels in order. However, the function does not take into account that there a holes in the HDMI channel map. Additionally, the function tries to disable a slot by using AC_VERB_SET_CHAN_SLOT with parameter ((alsa_ch << 8) | 0xf), while the correct parameter is ((0xf << 8) | hdmi_slot), i.e. the slot should be unassigned, not the ALSA channel. Fix both of the issues for non-ALSA-default layouts. Tested on Intel HDMI with a speaker mask of FL | FR | FC | RC, which causes CA 0x06 to be selected for 4-channel audio, which causes incorrect output (sound destined to RC goes to FC and FC goes nowhere) without the patch.

commit 8adbf78e upstream. Git commit 4f37a68c "s390: Use direct ktime path for s390 clockevent device" makes use of the CLOCK_EVT_FEAT_KTIME clockevent option to avoid the delta calculation with ktime_get() in clockevents_program_event and the get_tod_clock() in s390_next_event. This is based on the assumption that the difference between the internal ktime and the hardware clock is reflected in the wall_to_monotonic delta. But this is not true, the ntp corrections are applied via changes to the tk->mult multiplier and this is not reflected in wall_to_monotonic. In theory this could be solved by using the raw monotonic clock but it is simpler to switch back to the standard clock delta calculation. Signed-off-by:

commit e9baa9d9 upstream. It appears that in the DMA40 driver the DMA tasklet will very often dereference memory for a descriptor just free:d from the DMA40 slab. Nothing happens because no other part of the driver has yet had a chance to claim this memory, but it's really nasty to dereference free:d memory, so let's check the flag before the descriptor is free and store it in a bool variable.
