While this shouldn't really be something that happens all that often, since we're going to be using the drm_dbg_* log helpers in DRM helpers it's technically possible that a driver could use an AUX adapter before it's been associated with it's respective drm_device. While drivers should take care to avoid this, there's likely going to be situations where it's difficult to workaround. And since other logging helpers in the kernel tend to be OK with NULL pointers (for instance, passing a NULL pointer to a "%s" argument for a printk-like function in the kernel doesn't break anything), we should do the same for ours.

Since this is one of the few functions in drm_dp_mst_topology.c that doesn't have any way of getting access to a drm_device, let's pass the drm_dp_mst_topology_mgr down to this function so that it can use drm_dbg_kms(). Signed-off-by:

Since we're about to be using drm_dbg_*() throughout the DP helpers, we'll need to be able to access the DRM device in the dual mode DP helpers as well. Note however that since drm_dp_dual_mode_detect() can be called with DDC adapters that aren't part of a drm_dp_aux struct, we need to pass down the drm_device to these functions instead of using drm_dp_aux.

Since we're about to convert everything in drm_dp_helper.c over to using drm_dbg_*(), let's also make our logging more consistent in drm_dp_helper.c while we're at it to ensure that we always print the name of the AUX channel in question. Signed-off-by:

The docs we had for drm_dp_aux_init() and drm_dp_aux_register() were mostly correct, except for the fact that they made the assumption that all AUX devices were grandchildren of their respective DRM devices. This is the case for most normal GPUs, but is almost never the case with SoCs and display bridges. So, let's fix this documentation to clarify when the right time to use drm_dp_aux_init() or drm_dp_aux_register() is. Signed-off-by:

Lyude Paul authored
This is something that we've wanted for a while now: the ability to actually look up the respective drm_device for a given drm_dp_aux struct. This will also allow us to transition over to using the drm_dbg_*() helpers for debug message printing, as we'll finally have a drm_device to reference for doing so. Note that there is one limitation with this - because some DP AUX adapters exist as platform devices which are initialized independently of their respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be non-NULL until drm_dp_aux_register() has been called. We make sure to point this out in the documentation for struct drm_dp_aux. v3: * Add WARN_ON_ONCE() to drm_dp_aux_register() if drm_dev isn't filled out Signed-off-by:

On bochs DRM driver, the execution of "setterm --blank force" results in a frozen screen instead of a blank screen. It's due to the lack of the screen blanking support in its code. Actually, the QEMU bochs vga side can switch to the blanking mode when the bit 0x20 is cleared on VGA_ATT_IW register (0x3c0), which updates ar_index in QEMU side. So, essentially, we'd just need to clear the bit at pipe disable callback; that's what this patch does essentially. However, a tricky part is that the access via VGA_ATT_IW is done in "flip-flop"; the first write is for index and the second write is for the data like palette. Meanwhile, in the current bochs DRM driver, the flip-flop wasn't considered, and it calls only the register update once with the value 0x20. The spec and the actual VGA implementation in QEMU suggests that the flip flop flag is discarded by reading the CRTC index register (VGA_IS1_RC, 0x3da). So, in this patch, we add the helper to read a byte and the call to clear the flip flop flag before changing the blank / unblank setup via VGA_ATT_IW register. v1->v2: * discard ar_flip_flop by reading 0x3da, add bochs_vga_readb() * include video/vga.h for VGA register definitions * move the blank/unblank code to bochs_hw_blank() Signed-off-by:

[Bug][DP501] If ASPEED P2A (PCI to AHB) bridge is disabled and disallowed for CVE_2019_6260 item3, and then the monitor's EDID is unable read through Parade DP501. The reason is the DP501's FW is mapped to BMC addressing space rather than Host addressing space. The resolution is that using "pci_iomap_range()" maps to DP501's FW that stored on the end of FB (Frame Buffer). In this case, FrameBuffer reserves the last 2MB used for the image of DP501.

The commit 7cbb93d8 ("drm/ast: Use managed pci functions") converted a few PCI accessors to the managed API and dropped the manual pci_iounmap() calls, but it seems to have forgotten converting pci_iomap() to the managed one. It resulted in the leftover resources after the driver unbind. Let's fix them. Fixes: 7cbb93d8 ("drm/ast: Use managed pci functions") Signed-off-by:
