Allocate a shadow buffer for drivers that require deferred I/O and use it as framebuffer memory. Fixes driver errors about being "Unable to handle kernel NULL pointer dereference at virtual address" or "Unable to handle kernel paging request at virtual address". The patch splits drm_fbdev_dma_driver_fbdev_probe() in an initial allocation, which creates the DMA-backed buffer object, and a tail that sets up the fbdev data structures. There is a tail function for direct memory mappings and a tail function for deferred I/O with the shadow buffer. It is no longer possible to use deferred I/O without shadow buffer. It can be re-added if there exists a reliably test for usable struct page in the allocated DMA-backed buffer object.

The internal microphone on ASUS Vivobook N705UD / X705UD laptops is broken: the microphone appears in userspace (e.g. Gnome settings) but no sound is detected. I bisected it to commit 3b4309546b48 ("ALSA: hda: Fix headset detection failure due to unstable sort"). I figured out the cause: 1. The initial pins enabled for the ALC256 driver are: cfg->inputs == { { pin=0x19, type=AUTO_PIN_MIC, is_headset_mic=1, is_headphone_mic=0, has_boost_on_pin=1 }, { pin=0x1a, type=AUTO_PIN_MIC, is_headset_mic=0, is_headphone_mic=0, has_boost_on_pin=1 } } 2. Since 2017 and commits c1732ede5e8 ("ALSA: hda/realtek - Fix headset and mic on several ASUS laptops with ALC256") and 28e8af8a163 ("ALSA: hda/realtek: Fix mic and headset jack sense on ASUS X705UD"), the quirk ALC256_FIXUP_ASUS_MIC is also applied to ASUS X705UD / N705UD laptops. This added another internal microphone on pin 0x13: cfg->inputs == { { pin=0x13, type=AUTO_PIN_MIC, is_headset_mic=0, is_headphone_mic=0, has_boost_on_pin=1 }, { pin=0x19, type=AUTO_PIN_MIC, is_headset_mic=1, is_headphone_mic=0, has_boost_on_pin=1 }, { pin=0x1a, type=AUTO_PIN_MIC, is_headset_mic=0, is_headphone_mic=0, has_boost_on_pin=1 } } I don't know what this pin 0x13 corresponds to. To the best of my knowledge, these laptops have only one internal microphone. 3. Before 2025 and commit 3b4309546b48 ("ALSA: hda: Fix headset detection failure due to unstable sort"), the sort function would let the microphone of pin 0x1a (the working one) *before* the microphone of pin 0x13 (the phantom one). 4. After this commit 3b4309546b48, the fixed sort function puts the working microphone (pin 0x1a) *after* the phantom one (pin 0x13). As a result, no sound is detected anymore. It looks like the quirk ALC256_FIXUP_ASUS_MIC is not needed anymore for ASUS Vivobook X705UD / N705UD laptops. Without it, everything works fine: - the internal microphone is detected and records actual sound, - plugging in a jack headset is detected and can record actual sound with it, - unplugging the jack headset makes the system go back to internal microphone and can record actual sound.

The initial pins enabled for the ALC256 driver are: cfg->inputs == { { pin=0x19, type=AUTO_PIN_MIC, is_headset_mic=1, is_headphone_mic=0, has_boost_on_pin=1 }, { pin=0x1a, type=AUTO_PIN_MIC, is_headset_mic=0, is_headphone_mic=0, has_boost_on_pin=1 } } 2. Since 2017 and commits c1732ede5e8 ("ALSA: hda/realtek - Fix headset and mic on several ASUS laptops with ALC256") and 28e8af8a163 ("ALSA: hda/realtek: Fix mic and headset jack sense on ASUS X705UD"), the quirk ALC256_FIXUP_ASUS_MIC is also applied to ASUS X705UD / N705UD laptops. This added another internal microphone on pin 0x13: cfg->inputs == { { pin=0x13, type=AUTO_PIN_MIC, is_headset_mic=0, is_headphone_mic=0, has_boost_on_pin=1 }, { pin=0x19, type=AUTO_PIN_MIC, is_headset_mic=1, is_headphone_mic=0, has_boost_on_pin=1 }, { pin=0x1a, type=AUTO_PIN_MIC, is_headset_mic=0, is_headphone_mic=0, has_boost_on_pin=1 } } I don't know what this pin 0x13 corresponds to. To the best of my knowledge, these laptops have only one internal microphone. 3. Before 2025 and commit 3b4309546b48 ("ALSA: hda: Fix headset detection failure due to unstable sort"), the sort function would let the microphone of pin 0x1a (the working one) *before* the microphone of pin 0x13 (the phantom one). 4. After this commit 3b4309546b48, the fixed sort function puts the working microphone (pin 0x1a) *after* the phantom one (pin 0x13). As a result, no sound is detected anymore. It looks like the quirk ALC256_FIXUP_ASUS_MIC is not needed anymore for ASUS Vivobook X705UD / N705UD laptops. Without it, everything works fine: - the internal microphone is detected and records actual sound, - plugging in a jack headset is detected and can record actual sound with it, - unplugging the jack headset makes the system go back to internal microphone and can record actual sound.
