Migration range from system memory to VRAM, if system page can not be
locked or unmapped, we do partial migration and leave some pages in
system memory. Several bugs found to copy pages and update GPU mapping
for this situation:
1. copy to vram should use migrate->npage which is total pages of range
as npages, not migrate->cpages which is number of pages can be migrated.
2. After partial copy, set VRAM res cursor as j + 1, j is number of
system pages copied plus 1 page to skip copy.
3. copy to ram, should collect all continuous VRAM pages and copy
together.
4. Call amdgpu_vm_update_range, should pass in offset as bytes, not
as number of pages.

While it works, for the most part, to assume that the panel has
finished probing when devm_of_dp_aux_populate_ep_devices() returns,
it's a bit fragile. This is talked about at length in commit
a1e3667a9835 ("drm/bridge: ti-sn65dsi86: Promote the AUX channel to
its own sub-dev").
When reviewing the ps8640 code, I managed to convince myself that it
was OK not to worry about it there and that maybe it wasn't really
_that_ fragile. However, it turns out that it really is. Simply
hardcoding panel_edp_probe() to return -EPROBE_DEFER was enough to put
the boot process into an infinite loop. I believe this manages to trip
the same issues that we used to trip with the main MSM code where
something about our actions trigger Linux to re-probe previously
deferred devices right away and each time we try again we re-trigger
Linux to re-probe.
Let's fix this using the callback introduced in the patch ("drm/dp:
Callbacks to make it easier for drivers to use DP AUX bus properly").
When using the new callback, we have to be a little careful. The
probe_done() callback is no longer always called in the context of
our probe routine. That means we can't rely on being able to return
-EPROBE_DEFER from it. We re-jigger the order of things a bit to
account for that.
With this change, the device still boots (though obviously the panel
doesn't come up) if I force panel-edp to always return
-EPROBE_DEFER. If I fake it and make the panel probe exactly once it
also works.

This adds a devm managed version of drm_bridge_add(). Like other
"devm" function listed in drm_bridge.h, this function takes an
explicit "dev" to use for the lifetime management. A few notes:
* In general we have a "struct device" for bridges that makes a good
candidate for where the lifetime matches exactly what we want.
* The "bridge->dev->dev" device appears to be the encoder
device. That's not the right device to use for lifetime management.

As talked about in this patch in the kerneldoc of
of_dp_aux_populate_ep_device() and also in the past in commit
a1e3667a9835 ("drm/bridge: ti-sn65dsi86: Promote the AUX channel to
its own sub-dev"), it can be difficult for eDP controller drivers to
know when the panel has finished probing when they're using
of_dp_aux_populate_ep_devices().
The ti-sn65dsi86 driver managed to solve this because it was already
broken up into a bunch of sub-drivers. That means we could solve the
problem there by adding a new sub-driver to get the panel. We could
use the traditional -EPROBE_DEFER retry mechansim to handle the case
where the panel hadn't probed yet.
In parade-ps8640 we didn't really solve this. The code just expects
the panel to be ready right away. While reviewing the code originally
I had managed to convince myself it was fine to just expect the panel
right away, but additional testing has shown that not to be the
case. We could fix parade-ps8640 like we did ti-sn65dsi86 but it's
pretty cumbersome (since we're not already broken into multiple
drivers) and requires a bunch of boilerplate code.
After discussion [1] it seems like the best solution for most people
is:
- Accept that there's always at most one device that will probe as a
result of the DP AUX bus (it may have sub-devices, but there will be
one device _directly_ probed).
- When that device finishes probing, we can just have a call back.
This patch implements that idea. We'll now take a callback as an
argument to the populate function. To make this easier to land in
pieces, we'll make wrappers for the old functions. The functions with
the new name (which make it clear that we only have one child) will
take the callback and the functions with the old name will temporarily
wrap.

Our internal teams have identified a few additional engine registers
that are worth inspecting in error state dumps during development &
debug. Let's capture and print them as part of our error dump.
For simplicity we'll just dump these registers on gen11 and beyond.
Most of these registers have existed since earlier platforms (e.g., gen6
or gen7) but were initially introduced only for a subset of the
platforms' engines; gen11 seems to be where they became available on all
engines.

As with EU masks, it's easier to store subslice/DSS masks internally in
a format that's more natural for the driver to work with, and then only
covert into the u8[] uapi form when the query ioctl is invoked. Since
the hardware design changed significantly with Xe_HP, we'll use a union
to choose between the old "hsw-style" subslice masks or the newer xehp
mask. HSW-style masks will be stored in an array of u8's, indexed by
slice (there's never more than 6 subslices per slice on older
platforms). For Xe_HP and beyond where slices no longer exist, we only
need a single bitmask. However we already know that this mask is
eventually going to grow too large for a simple u64 to hold, so we'll
represent it in a manner that can be operated on by the utilities in
linux/bitmap.h.
v2:
- Fix typo: BIT(s) -> BIT(ss) in gen9_sseu_device_status()
v3:
- Eliminate sseu->ss_stride and just calculate the stride while
specifically handling uapi. (Tvrtko)
- Use BITMAP_BITS() macro to refer to size of masks rather than
passing I915_MAX_SS_FUSE_BITS directly. (Tvrtko)
- Report compute/geometry DSS masks separately when dumping Xe_HP SSEU
info. (Tvrtko)
- Restore dropped range checks to intel_sseu_has_subslice(). (Tvrtko)
v4:
- Make the bitmap size macro check the size of the .xehp field rather
than the containing union. (Tvrtko)
- Don't add GEM_BUG_ON() intel_sseu_has_subslice()'s check for whether
slice or subslice ID exceed sseu->max_[sub]slices; various loops
in the driver are expected to exceed these, so we should just
silently return 'false.'
v5:
- Move XEHP_BITMAP_BITS() to the header so that we can also replace a
usage of I915_MAX_SS_FUSE_BITS in one of the inline functions.
(Bala)
- Change the local variable in intel_slicemask_from_xehp_dssmask() from
u16 to 'unsigned long' to make it a bit more future-proof.

Storing the EU mask internally in the same format the I915_QUERY
topology queries use makes the final copy_to_user() a bit simpler, but
makes the rest of the driver's SSEU more complicated and harder to
follow. Let's switch to an internal representation that's more natural:
Xe_HP platforms will be a simple array of u16 masks, whereas pre-Xe_HP
platforms will be a two-dimensional array, indexed by [slice][subslice].
We'll convert to the uapi format only when the query uapi is called.
v2:
- Drop has_common_ss_eumask. We waste some space repeating identical
EU masks for every single DSS, but the code is simpler without it.
(Tvrtko)
v3:
- Mask down EUs passed to sseu_set_eus at the callsite rather than
inside the function. (Tvrtko)
- Eliminate sseu->eu_stride and calculate it when needed. (Tvrtko)

Although gen11 and gen12 architectures supported the concept of multiple
slices, in practice all the platforms that were actually designed only
had a single slice (i.e., note the parameters to 'intel_sseu_set_info'

dropping the multi-slice logic from gen11+ platforms.

unexpected fusing. (Tvrtko)

Slice/subslice/EU information should be obtained via the topology
queries provided by the I915_QUERY interface; let's turn off support for
the old GETPARAM lookups on Xe_HP and beyond where we can't return
meaningful values.
The slice mask lookup is meaningless since Xe_HP doesn't support
traditional slices (and we make no attempt to return the various new
units like gslices, cslices, mslices, etc.) here.
The subslice mask lookup is even more problematic; given the distinct
masks for geometry vs compute purposes, the combined mask returned here
is likely not what userspace would want to act upon anyway. The value
is also limited to 32-bits by the nature of the GETPARAM ioctl which is
sufficient for the initial Xe_HP platforms, but is unable to convey the
larger masks that will be needed on other upcoming platforms. Finally,
the value returned here becomes even less meaningful when used on
multi-tile platforms where each tile will have its own masks.

Xe_HP has enough fundamental differences from previous platforms that it
makes sense to use a separate SSEU init function to keep things

Someone made the mistake to try reading EDID from the backlight i2c
adapter. This has been wrong for a very long time but since we read out
the modes correctly on init and don't hotplug lvds it has been working
anyway. Correct this by using connector->ddc instead of
encoder->i2c_bus. Both PSB and CDV are affected but this bug.

We're moving all uses of ddc_bus to drm_connector where they belong.
The initialization of the gma_i2c_chan for Oaktrail is a bit backwards
so it required improvements. Also cleanup the error handling in
oaktrail_lvds_init(). Since this is the last user of
gma_encoder->ddc_bus we can remove it.

If a GEM object is allocated, and then exported as a dma-buf fd which is
mmap'd before or without the GEM buffer being directly mmap'd, the
vma_node could be unitialized. This leads to a situation where the CPU
mapping is not correctly torn down in drm_vma_node_unmap().

In commit a670ff578f1f ("drm/msm/dpu: always use mdp device to scale
bandwidth") we fully moved interconnect stuff to the DPU driver. This
had no change for sc7180 but _did_ have an impact for other SoCs. It
made them match the sc7180 scheme.
Unfortunately, the sc7180 scheme seems like it was a bit broken.
Specifically the interconnect needs to be on for more than just the
DPU driver's AXI bus. In the very least it also needs to be on for the
DSI driver's AXI bus. This can be seen fairly easily by doing this on
a ChromeOS sc7180-trogdor class device:
set_power_policy --ac_screen_dim_delay=5 --ac_screen_off_delay=10
sleep 10
cd /sys/bus/platform/devices/ae94000.dsi/power
echo on > control
When you do that, you'll get a warning splat in the logs about
"gcc_disp_hf_axi_clk status stuck at 'off'".
One could argue that perhaps what I have done above is "illegal" and
that it can't happen naturally in the system because in normal system
usage the DPU is pretty much always on when DSI is on. That being
said:
* In official ChromeOS builds (admittedly a 5.4 kernel with backports)
we have seen that splat at bootup.
* Even though we don't use "autosuspend" for these components, we
don't use the "put_sync" variants. Thus plausibly the DSI could stay
"runtime enabled" past when the DPU is enabled. Techncially we
shouldn't do that if the DPU's suspend ends up yanking our clock.
Let's change things such that the "bare minimum" request for the
interconnect happens in the mdss driver again. That means that all of
the children can assume that the interconnect is on at the minimum
bandwidth. We'll then let the DPU request the higher amount that it
wants.
It should be noted that this isn't as hacky of a solution as it might
initially appear. Specifically:
* Since MDSS and DPU individually get their own references to the
interconnect then the framework will actually handle aggregating
them. The two drivers are _not_ clobbering each other.
* When the Qualcomm interconnect driver aggregates it takes the max of
all the peaks. Thus having MDSS request a peak, as we're doing here,
won't actually change the total interconnect bandwidth (it won't be
added to the request for the DPU). This perhaps explains why the
"average" requested in MDSS was historically 0 since that one
_would_ be added in.
NOTE also that in the downstream ChromeOS 5.4 and 5.15 kernels, we're
also seeing some RPMH hangs that are addressed by this fix. These
hangs are showing up in the field and on _some_ devices with enough
stress testing of suspend/resume. Specifically right at suspend time
with a stack crawl that looks like this (from chromeos-5.15 tree):

We don't completely understand all the mechanisms in play, but the
hang seemed to come and go with random factors. It's not terribly
surprising that the hang is gone after this patch since the line of
code that was failing is no longer present in the kernel.

dp_catalog_ctrl_reset() will software reset DP controller. But it will
not reset programmable registers to default value. DP driver still have
to clear mask bits to interrupt status registers to disable interrupts
after software reset of controller.
At current implementation, dp_ctrl_reset_irq_ctrl() will software reset dp
controller but did not call dp_catalog_ctrl_enable_irq(false) to clear hpd
related interrupt mask bits to disable hpd related interrupts due to it
mistakenly think hpd related interrupt mask bits will be cleared by software
reset of dp controller automatically. This mistake may cause system to crash
during suspending procedure due to unexpected irq fired and trigger event
thread to access dp controller registers with controller clocks are disabled.
This patch fixes system crash during suspending problem by removing "enable"
flag condition checking at dp_ctrl_reset_irq_ctrl() so that hpd related
interrupt mask bits are cleared to prevent unexpected from happening.

The kernel test robot reports a compile warning due the ssd130x_spi_table
variable being defined but not used. This happen when ssd130x-spi driver
is built-in instead of being built as a module, i.e:
CC drivers/gpu/drm/solomon/ssd130x-spi.o
AR drivers/base/firmware_loader/built-in.a
AR drivers/base/built-in.a
CC kernel/trace/trace.o
drivers/gpu/drm/solomon/ssd130x-spi.c:155:35: warning: ‘ssd130x_spi_table’ defined but not used [-Wunused-const-variable=]
155 | static const struct spi_device_id ssd130x_spi_table[] = {
| ^~~~~~~~~~~~~~~~~
The driver shouldn't need a SPI device ID table and only have an OF device
ID table, but the former is needed to workaround an issue in the SPI core.
This always reports a MODALIAS of the form "spi:<device>" even for devices
registered through Device Trees.
But the table is only needed when the driver built as a module to populate
the .ko alias info. It's not needed when the driver is built-in the kernel.
