2018-07-30drm/armada: switch legacy modeset to atomic modesetRussell King2-103/+1
Switch the legacy set_config() method to use the atomic modeset helper, which allows us to get rid of the legacy dpms, prepare, commit, mode_set, mode_set_base and disable helper methods. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: enable atomic modeset supportRussell King2-5/+7
Enable atomic modeset helpers, and internal DRM use of atomic modeset with armada-drm. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: implement atomic_enable()/atomic_disable() methodsRussell King1-0/+71
Implement the atomic_enable()/atomic_disable() methods used by the atomic modeset helpers. atomic_disable() will need some transitional code during conversion to ensure proper ordering is maintained. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: unhook dpms state from armada_drm_crtc_update()Russell King1-6/+5
Explicitly pass in the desired enable/disable state into armada_drm_crtc_update() rather than having it use the DPMS state stored in our crtc structure. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: push responsibility for clock management to backendRussell King3-13/+27
Push responsibility for managing the clock during DPMS down into the variant backend, rather than the CRTC layer having knowledge of its state. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: handle atomic modeset crtc eventsRussell King2-0/+34
Prepare handling for atomic modeset CRTC events. Currently, using the transition helpers, CRTC events do not exist, but once we switch to proper atomic modeset, they have to be handled. We queue an event for the next vblank in two places: - armada_drm_crtc_atomic_flush() provided we aren't doing an atomic modeset. - armada_drm_crtc_commit() if we are committing a modeset. This ensures that the event is sent at the correct time (after all updates have been written to the hardware and after the following vblank.) Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: clean up SPU_ADV_REGRussell King3-9/+8
Rather than writing all bits of SPU_ADV_REG on modeset, only write what we need to change, and initialise the register in the variant initialisation. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: update debug in armada_drm_crtc_mode_set_nofb()Russell King1-10/+9
Update debug to use KMS level, and print the mode using the standard format for mode lines, but print the adjusted CRTC parameters as that's what we will be programming for. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: move sync signal polarity to mode_set_nofb() methodRussell King2-26/+22
For atomic modeset, we need to set the sync signal polarities from the CRTC state structure rather than the legacy mode structure stored in CRTC. In any case, we should update this from our mode_set_nofb() method, rather than the commit() method. Move it there, and ensure that armada_drm_crtc_update() will not overwrite these bits. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: push interlace calculation into armada_drm_plane_calc()Russell King3-28/+30
Push the interlaced frame calculation down into armada_drm_plane_calc() which needs to apply the same correction for both the overlay and primary planes. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: provide pitches from armada_drm_plane_calc_addrs()Russell King3-13/+20
Provide the framebuffer pitches from armada_drm_plane_calc_addrs() as well as the base addresses for each plane. Since this is now about more than just addresses, rename to armada_drm_plane_calc(). Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: pass plane state into armada_drm_plane_calc_addrs()Russell King3-18/+16
armada_drm_plane_calc_addrs() gets all its information from the plane state, so it makes sense to pass the plane state pointer down into this function, rather than extracting the information in identical ways, sometimes a couple of layers up. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: move armada_drm_mode_config_funcs to armada_drv.cRussell King5-11/+11
Move the armada_drm_mode_config_funcs to armada_drv.c, since this now has less to do with FBs than it does with general mode configuration. In doing so, we need to make armada_fb_create() visible to armada_drv.c, which reveals a function name clash with armada_fbdev.c. Rename the version in armada_fbdev.c. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: add plane colorspace propertiesRussell King1-1/+32
Use the DRM standard plane properties for specifying the YUV colour encoding parameter. Our colour range is fixed at limited range. Since we are transitioning to atomic modeset, we need to explicitly add handling of these properties to our atomic_set_property() method, but once the transition is complete, these will be removed. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: remove crtc YUV colourspace propertiesRussell King3-122/+0
Remove the unused CRTC colourspace properties - userspace does not make use of these. In any case, these are not a property of the CRTC, since they demonstrably only affect the video (overlay) plane, irrespective of the format of the graphics (primary) plane. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: move colorkey properties into overlay plane stateRussell King1-119/+132
Move the overlay plane colorkey properties into the plane state, keeping the existing driver behaviour to avoid breaking userspace. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: move CBSH properties into overlay plane stateRussell King2-29/+136
Move the contrast, brightness, and saturation properties to the overlay plane state structure, and call our overlay commit function to update the hardware via the planes atomic_update() method. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: move plane works to overlayRussell King3-12/+8
Only overlay makes use of these now, so move these to the overlay code. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: move primary plane to separate fileRussell King6-283/+318
Split out the primary plane support; this is now entirely separate from the CRTC support. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: use old_state for update tracking in atomic_update()Russell King3-173/+144
Rather than tracking the register state, we can now check the previous state and decide which registers need updating from that since the old plane state indicates the previous state which was programmed into the hardware. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: remove temporary crtc stateRussell King1-6/+6
Now that we have the CRTC using the atomic modeset transitional helper, there is no need to build a temporary crtc state anymore - we can use the CRTC atomic state directly. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: convert overlay plane to atomic stateRussell King3-120/+145
The overlay plane support updates asynchronously to the request, but the drm_plane_helper_update() transitional helper waits for a vblank event before releasing the framebuffer. Using the transitional helper would make the call block, which would introduce a performance regression. Convert the overlay plane update to use the atomic state structures and methods for the plane, but implement our own legacy update method rather than the transitional helper. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: convert page_flip to use primary plane atomic_update()Russell King1-26/+55
page_flip requests happen asynchronously, so we can't wait on the vblank event before returning to userspace, as the transitional plane update helper would do. Craft our own implementation that keeps the asynchronous behaviour of this request, while making use of the atomic infrastructure for the primary plane update. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: convert primary plane to atomic stateRussell King2-159/+157
Convert the primary plane as a whole to use its atomic state and the transitional helpers. The CRTC is also switched to use the transitional helpers for mode_set() and mode_set_base(). Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: reset all atomic state during driver initialisationRussell King1-0/+2
Reset the atomic state of any converted components during driver initialisation to ensure that we have the atomic state initialised for any component converted to atomic modeset. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: merge armada_drm_gra_plane_regs() into only callerRussell King1-31/+24
armada_drm_gra_plane_regs() is now only ever called from within armada_drm_primary_update_state(), so merge it into this function. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: use core of primary update_plane for mode setRussell King1-78/+59
Use the core of the update_plane method to configure the primary plane within mode_set() rather than duplicating this code. This moves us closer to the same code structure that the atomic modeset transitional helpers will use. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: move mode set vblank handling and disable/enableRussell King2-21/+21
Move the mode set vblank handling and controller enable/disable to the prepare() and commit() callbacks. This will be needed when we move to mode_set_nofb() as we should not enable the controller without the plane coordinates and location having been properly updated. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: add rectangle helpersRussell King3-9/+21
Add helpers to convert rectangle width/height and x/y to register values. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: clean up armada_drm_crtc_page_flip()Russell King1-12/+0
drm_mode_page_flip_ioctl() already takes care of checking the framebuffer format, and also assigns primary->fb after a successful call to this handler. These are both redundant, and can be removed. Signed-off-by: Russell King <[email protected]>
2018-07-30drm/armada: Adding new typedef vm_fault_tSouptick Joarder1-13/+2
Use new return type vm_fault_t for fault handler in struct vm_operations_struct. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. commit 1c8f422059ae ("mm: change return type to vm_fault_t") Previously vm_insert_pfn() returns err which driver mapped into VM_FAULT_* type. The new function vmf_insert_pfn() will replace this inefficiency by returning VM_FAULT_* type.

2018-07-30drm/armada: Replace drm_dev_unref with drm_dev_putThomas Zimmermann1-3/+3

2018-07-29squashfs: be more careful about metadata corruptionLinus Torvalds4-5/+16
Anatoly Trosinenko reports that a corrupted squashfs image can cause a kernel oops. It turns out that squashfs can end up being confused about negative fragment lengths. The regular squashfs_read_data() does check for negative lengths, but squashfs_read_metadata() did not, and the fragment size code just blindly trusted the on-disk value. Fix both the fragment parsing and the metadata reading code.

2018-07-29ext4: fix check to prevent initializing reserved inodesTheodore Ts'o2-8/+5
Commit 8844618d8aa7: "ext4: only look at the bg_flags field if it is valid" will complain if block group zero does not have the EXT4_BG_INODE_ZEROED flag set. Unfortunately, this is not correct, since a freshly created file system has this flag cleared. It gets almost immediately after the file system is mounted read-write --- but the following somewhat unlikely sequence will end up triggering a false positive report of a corrupted file system: mkfs.ext4 /dev/vdc mount -o ro /dev/vdc /vdc mount -o remount,rw /dev/vdc Instead, when initializing the inode table for block group zero, test to make sure that itable_unused count is not too large, since that is the case that will result in some or all of the reserved inodes getting cleared. This fixes the failures reported by Eric Whiteney when running generic/230 and generic/231 in the the nojournal test case.

2018-07-27Revert "MIPS: BCM47XX: Enable 74K Core ExternalSync for PCIe erratum"Rafał Miłecki2-9/+0
This reverts commit 2a027b47dba6 ("MIPS: BCM47XX: Enable 74K Core ExternalSync for PCIe erratum"). Enabling ExternalSync caused a regression for BCM4718A1 (used e.g. in Netgear E3000 and ASUS RT-N16): it simply hangs during PCIe initialization. It's likely that BCM4717A1 is also affected. I didn't notice that earlier as the only BCM47XX devices with PCIe I own are: 1) BCM4706 with 2 x 14e4:4331 2) BCM4706 with 14e4:4360 and 14e4:4331 it appears that BCM4706 is unaffected. While BCM5300X-ES300-RDS.pdf seems to document that erratum and its workarounds (according to quotes provided by Tokunori) it seems not even Broadcom follows them. According to the provided info Broadcom should define CONF7_ES in their SDK's mipsinc.h and implement workaround in the si_mips_init(). Checking both didn't reveal such code. It *could* mean Broadcom also had some problems with the given workaround.
