2 years agodrm: mxsfb: Implement LCDIF scanout CRC32 support
Marek Vasut [Fri, 29 Apr 2022 21:23:13 +0000 (23:23 +0200)]
drm: mxsfb: Implement LCDIF scanout CRC32 support

The LCDIF controller as present in i.MX28/i.MX6SX/i.MX8M Mini/Nano has
CRC_STAT register, which contains CRC32 of the frame as it was clocked
out of the DPI interface of the LCDIF. This is most likely meant as a
functional safety feature.

Unfortunately, there is zero documentation on how the CRC32 is calculated,
there is no documentation of the polynomial, the init value, nor on which
data is the checksum applied.

By applying brute-force on 8 pixel / 2 line frame, which is the minimum
size LCDIF would work with, it turns out the polynomial is CRC32_POLY_LE
0xedb88320 , init value is 0xffffffff , the input data are bitrev32()
of the entire frame and the resulting CRC has to be also bitrev32()ed.

Doing this calculation in kernel for each frame is unrealistic due to the
CPU demand, so attach the CRC collected from hardware to a frame instead.
The DRM subsystem already has an interface for this purpose and the CRC
can be accessed e.g. via debugfs:
"
$ echo auto > /sys/kernel/debug/dri/1/crtc-0/crc/control
$ cat /sys/kernel/debug/dri/1/crtc-0/crc/data
0x0000408c 0xa4e5cdd8
0x0000408d 0x72f537b4
"
The per-frame CRC can be used by userspace e.g. during automated testing,
to verify that whatever buffer was sent to be scanned out was actually
scanned out of the LCDIF correctly.

drm/nouveau/subdev/bus: Ratelimit logging for fault errors

There's plenty of ways to fudge the GPU when developing on nouveau by
mistake, some of which can result in nouveau seriously spamming dmesg with
fault errors. This can be somewhat annoying, as it can quickly overrun the
message buffer (or your terminal emulator's buffer) and get rid of actually
useful feedback from the driver. While working on my new atomic only MST
branch, I ran into this issue a couple of times.

So, let's fix this by adding nvkm_error_ratelimited(), and using it to
ratelimit errors from faults. This should be fine for developers, since
it's nearly always only the first few faults that we care about seeing.
Plus, you can turn off rate limiting in the kernel if you really need to.

Fbdev's deferred-I/O code uses the two related page->index and

can be different. Because GEM buffer objects are mapped at an offset
in the DRM device file, page->index has this offset added to it as well.
We currently don't hit this case in DRM, because all affected mappings
of GEM memory are performed with an internal, intermediate shadow buffer.

The value of page->index is required by page_mkclean(), which we
call to reset the mappings during the writeback phase of the deferred

fbdev: Track deferred-I/O pages in pageref struct

fb_deferred_io_pageref. Maintain a list of pagerefs for the pages
that have to be written back to video memory. Update all affected
drivers.

As with pages before, fbdev acquires a pageref when an mmaped page
of the framebuffer is being written to. It holds the pageref in a
list of all currently written pagerefs until it flushes the written
pages to video memory. Writeback occurs periodically. After writeback
fbdev releases all pagerefs and builds up a new dirty list until the
next writeback occurs.

Using pagerefs has a number of benefits.

For pages of the framebuffer, the deferred I/O code used struct
page.lru as an entry into the list of dirty pages. The lru field is
owned by the page cache, which makes deferred I/O incompatible with
some memory pages (e.g., most notably DRM's GEM SHMEM allocator).
struct fb_deferred_io_pageref now provides an entry into a list of
dirty framebuffer pages, freeing lru for use with the page cache.

Drivers also assumed that struct page.index is the page offset into
the framebuffer. This is not true for DRM buffers, which are located
at various offset within a mapped area. struct fb_deferred_io_pageref
explicitly stores an offset into the framebuffer. struct page.index
is now only the page offset into the mapped area.

These changes will allow DRM to use fbdev deferred I/O without an
intermediate shadow buffer.

* fix grammar in comment

fbdev: Put mmap for deferred I/O into drivers

The fbdev mmap function fb_mmap() unconditionally overrides the
driver's implementation if deferred I/O has been activated. This
makes it hard to implement mmap with anything but a vmalloc()'ed
software buffer. That is specifically a problem for DRM, where
video memory is maintained by a memory manager.

Leave the mmap handling to drivers and expect them to call the
helper for deferred I/O by thmeselves.

2 years agodrm: bridge: adv7511: use non-legacy mode for CEC RX
Alvin Šipraga [Sat, 23 Apr 2022 12:08:53 +0000 (14:08 +0200)]
drm: bridge: adv7511: use non-legacy mode for CEC RX

The ADV7511 family of bridges supports two modes for CEC RX: legacy and
non-legacy mode. The only difference is whether the chip uses a single
CEC RX buffer, or uses all three available RX buffers. Currently the
adv7511 driver uses legacy mode.

While debugging a stall in CEC RX on an ADV7535, we reached out to
Analog Devices, who suggested to use non-legacy mode instead.  According
to the programming guide for the ADV7511 [1], and the register control
manual of the ADV7535 [2], this is the default behaviour on reset. As
previously stated, the adv7511 driver currently overrides this to legacy
mode.

This patch updates the adv7511 driver to instead use non-legacy mode
with all three CEC RX buffers. As a result of this change, we no longer
experience any stalling of CEC RX with the ADV7535. It is not known why
non-legacy mode solves this particular issue, but besides this, no
functional change is to be expected by this patch. Please note that this
has only been tested on an ADV7535.

What follows is a brief description of the non-legacy mode interrupt
handling behaviour. The programming guide in [1] gives a more detailed
explanation.

With three RX buffers, the interrupt handler checks the CEC_RX_STATUS
register (renamed from CEC_RX_ENABLE in this patch), which contains
2-bit psuedo-timestamps for each of the RX buffers. The RX timestamps
for each buffer represent the time of arrival for the CEC frame held in
a given buffer, with lower timestamp values indicating chronologically
older frames. A special value of 0 indicates that the given RX buffer
is inactive and should be skipped. The interrupt handler parses these
timestamps and then reads the active RX buffers in the prescribed order
using the same logic as before. Changes have been made to ensure that
the correct RX buffer is cleared after processing. This clearing
procesure also sets the timestamp of the given RX buffer to 0 to mark it
as inactive.

[1] https://www.analog.com/media/en/technical-documentation/user-guides/ADV7511_Programming_Guide.pdf
    cf. CEC Map, register 0x4A, bit 3, default value 1:
    0 = Use only buffer 0 to store CEC frames (Legacy mode)
    1 = Use all 3 buffers to stores the CEC frames (Non-legacy mode)

[2] The ADV7535 register control manual is under NDA, but trust me when
    I say that non-legacy CEC RX mode is the default here too. Here the
    register is offset by 0x70 and has an address of 0xBA in the DSI_CEC
    regiser map.

drm: handle kernel fences in drm_gem_plane_helper_prepare_fb v2

drm_gem_plane_helper_prepare_fb() was using
drm_atomic_set_fence_for_plane() which ignores all implicit fences when an
explicit fence is already set. That's rather unfortunate when the fb still
has a kernel fence we need to wait for to avoid presenting garbage on the
screen.

So instead update the fence in the plane state directly. While at it also
take care of all potential GEM objects and not just the first one.

Also remove the now unused drm_atomic_set_fence_for_plane() function, new
drivers should probably use the atomic helpers directly.

v2: improve kerneldoc, use local variable and num_planes, WARN_ON_ONCE
    on missing planes.

Paolo Bonzini [Fri, 29 Apr 2022 18:43:04 +0000 (14:43 -0400)]
KVM: x86: work around QEMU issue with synthetic CPUID leaves

Synthesizing AMD leaves up to 0x80000021 caused problems with QEMU,
which assumes the *host* CPUID[0x80000000].EAX is higher or equal
to what KVM_GET_SUPPORTED_CPUID reports.

This causes QEMU to issue bogus host CPUIDs when preparing the input
to KVM_SET_CPUID2.  It can even get into an infinite loop, which is
only terminated by an abort():

   cpuid_data is full, no space for cpuid(eax:0x8000001d,ecx:0x3e)

To work around this, only synthesize those leaves if 0x8000001d exists
on the host.  The synthetic 0x80000021 leaf is mostly useful on Zen2,
which satisfies the condition.

non-init mm is inherently dangerous and flawed, as the only reason to use
an mm other than init_mm is to walk a userspace mapping, and
lookup_address_in_pgd() does not play nice with userspace mappings, e.g.
doesn't disable IRQs to block TLB shootdowns and doesn't use READ_ONCE()
