由 Miquel Raynal 提交于
The block responsible of parsing the DT for the number of chip-select lines uses an 'if/else if/else if' block. The content of the second and third 'else if' conditions are: 1/ the actual condition to enter the sub-block and 2/ the operation to do in this sub-block. [...] else if (condition1_to_enter && action1() == failed) raise_error(); else if (condition2_to_enter && action2() == failed) raise_error(); [...] In case of failure, the sub-block is entered and an error raised. Otherwise, in case of success, the code would continue erroneously in the next 'else if' statement because it did not failed (and did not enter the first 'else if' sub-block). The first 'else if' refers to legacy bindings while the second 'else if' refers to new bindings. The second 'else if', which is entered erroneously, checks for the 'reg' property, which, for old bindings, does not mean anything because it would not be the number of CS available, but the regular register map of almost any DT node. This being said, the content of the 'reg' property being the register map offset and length, it has '2' values, so the number of CS in this situation is assumed to be '2'. When running nand_scan_ident() with 2 CS, the core will check for an array of chips. It will first issue a RESET and then a READ_ID. Of course this will trigger two timeouts because there is no chip in front of the second CS: [ 1.367460] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000080) [ 1.474292] marvell-nfc f2720000.nand: Timeout on CMDD (NDSR: 0x00000280) Indeed, this is harmless and the core will then assume there is only one valid CS. Fix the logic in the whole block by entering each sub-block just on the 'is legacy' condition, doing the action inside the sub-block. This way, when the action succeeds, the whole block is left. Furthermore, for both the old bindings and the new bindings the same logic was applied to retrieve the number of CS lines: using of_get_property() to get a size in bytes, converted in the actual number of lines by dividing it per sizeof(u32) (4 bytes). This is fine for the 'reg' property which is a list of the CS IDs but not for the 'num-cs' property which is directly the value of the number of CS. Anyway, no existing DT uses another value than 'num-cs = <1>' and no other value has ever been supported by the old driver (pxa3xx_nand.c). Remove this condition and apply a number of 1 CS anyway, as already described in the bindings. Finally, the 'reg' property of a 'nand' node (with the new bindings) gives the IDs of each CS line in use. marvell_nand.c driver first look at the number of CS lines that are present in this property. Better use of_property_count_elems_of_size() than dividing by 4 the size of the number of bytes returned by of_get_property().

We're currently failing to reset everything in display_info.hdmi which will potentially cause us to use stale information when swapping monitors. Eg. if the user replaces a HDMI 2.0 monitor with a HDMI 1.x monitor we will continue to think that the monitor supports scrambling. That will lead to a black screen since the HDMI 1.x monitor won't understand the scrambled signal. Fix the problem by clearing display_info.hdmi fully. And while at eliminate some duplicated code by calling drm_reset_display_info() in drm_add_display_info().

The reverted commit broke LVDS output on TBS A711 Tablet. That tablet has simple-panel node that has fixed pixel clock-frequency that A83T SoC used in the tablet can't generate exactly. Requested rate is 52000000 and rounded_rate is calculated as 51857142. It's close enough for it to work in practice, but with strict check in the reverted commit, the mode is rejected needlessly in this case. DT allows to specify a range of values for simple-panel/clock-frequency, but driver doesn't respect that ATM. Given that TBS A711 is the single user of sun4i-lvds driver, let's revert that commit for now, until a better solution for the problem is found.

Console driver is out of spec. The spec says: A driver MUST NOT decrement the available idx on a live virtqueue (ie. there is no way to “unexpose” buffers). and it does exactly that by trying to detach unused buffers without doing a device reset first. Defer detaching the buffers until device unplug. Of course this means we might get an interrupt for a vq without an attached port now. Handle that by discarding the consumed buffer.

For cleanup it's helpful to be able to simply scan all vqs and discard all data. Add an iterator to do that. Cc: stable@vger.kernel.org Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>

an allocated buffer doesn't need to be tied to a vq - only vq->vdev is ever used. Pass the function the just what it needs - the vdev. Cc: stable@vger.kernel.org Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>

This reverts commit 37c7c6c7. Turns out some drivers(most are FC drivers) may not use managed IRQ affinity, and has their customized .map_queues meantime, so still keep this code for avoiding regression.

Extended fix to: "Don't read EDID in atomic_check" Fix issue of missing dc_sink in .mode_valid in hot plug routine. Need to check dc_sink everytime in .get_modes hook after checking edid, since edid is not getting removed in hot unplug but dc_sink doesn't.

Extended fix to: "Don't read EDID in atomic_check" Fix display property not observed in GUI display after hot plug. Call drm_mode_connector_update_edid_property every time in .get_modes hook, due to the fact that edid property is getting removed from usermode ioctl DRM_IOCTL_MODE_GETCONNECTOR each time in hot unplug.

We shouldn't attempt to read EDID in atomic_check. We really shouldn't even be modifying the connector object, or any other non-state object, but this is a start at least. Moving EDID cleanup to dm_dp_mst_connector_destroy from dm_dp_destroy_mst_connector to ensure the EDID is still available for headless mode.

The below commit "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2" introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, it now preserves it. Since DC is currently not equipped to handle this we need to fail such a commit, otherwise we might see a corrupted screen. This is based on Shirish's previous approach but avoids adding all planes to the new atomic state which leads to a full update in DC for any commit, and is not what we intend. Theoretically DM should be able to deal with states with fully populated planes, even for simple updates, such as cursor updates. This should still be addressed in the future.
