[PATCH v4 00/23] Fix various bugs

[PATCH v4 00/23] Fix various bugs

[Simon Glass]

This series includes the patches needed to make make the EFI 'boot' test
work. That test has now been split off into a separate series along with
the EFI patches.

This series fixes these problems:
- sandbox memory-mapping conflict with PCI
- the fix for that causes the mbr test to crash as it sets up pointers
  instead of addresses for its 'mmc' commands
- the mmc and read commands which cast addresses to pointers
- a tricky bug to do with USB keyboard and stdio
- a few other minor things

Note that I would like to get this series applied before the change to
running unprivileged, since it has been almost a month and it will be a
trivial change once that is applied.

Changes in v4:
- Rebase to -next (on top of testc series)
- Drop patch to add UT_TESTF_CONSOLE_REC to bootflow tests

Changes in v3:
- Include the usb.h header file in all cases
- Correct the commit subject and message
- Add a Fixes tag
- use SZ_512 instead of 0x200

Changes in v2:
- Add many new patches to resolve all the outstanding test issues

Simon Glass (23):
  nvmxip: Drop the message on probe
  nvmxip: Avoid probing on boot

[PATCH v4 02/23] nvmxip: Avoid probing on boot

Devices should be probed when they are used, not before. Drop this
boot-time probing.

Once again, adding in the corstone1000 maintainers as the platform that
actually uses this.

Just to mention that Abdellatif was added automatically by patman for
the first version, but if there is no reply, after v2 I tend to drop
it back, to avoid sending too many emails.

[PATCH v4 03/23] test/py: Fix some pylint warnings in test_ut.py

[Simon Glass]

Tidy up most of these warnings. Remaining are four of these:

   R0914: Too many local variables

which can only by fixed by splitting things into functions, so that is
left for another time.

Part of this change was done by the flynt tool.

[PATCH v4 05/23] bootstd: Create a function to reset USB

[Simon Glass]

Set up a function for this, since it needs to be used from multiple test
files.

This test file is only used on sandbox, where USB is enabled, so drop
the local declaration of usb_started

[PATCH v4 06/23] usb: Drop old non-DM code

[Simon Glass]

The driver model deadline for USB was in 2019, so drop the old USB
keyboard code, to avoid needing to deal with the extra code path.

Drop the unnecessary #ifdef around USB_KBD_BOOT_REPORT_SIZE while we
are here.

[PATCH v4 11/23] test: mbr: Adjust test to drop 0x

[Simon Glass]

U-Boot commands typically don't need 0x to specify hex, since they use
hex by default. Adding 0x in this test is confusing since it suggests
that it is necessary. Drop it from the file.

Also use the %#x construct to get the 0x when needed.

[PATCH v4 12/23] sandbox: Change the range used for memory-mapping tags

[Simon Glass]

Sandbox keeps a table of addresses which map to pointers which are
outside its emulated DRAM. The current range from 10000000 conflicts
with the PCI range, meaning that if PCI mapping is on, that particular
address can be decoded by PCI instead of the table.

Fix this by moving the range up to the top of memory. Update the docs
while we are here.

[PATCH v4 14/23] sandbox: Unmap old tags

[Simon Glass]

So far unmapping has not been implemented. This means that if one test
maps a pointer to an address with map_sysmem(), then a second test can
use that same pointer, by mapping the address back to a pointer with
map_to_sysmem(). This is not really desirable, even if it doesn't
cause any problems at the moment.

Implement unmapping, to clean this up.

"base" isn't changed in the rest of the code, so we could just reuse it 
instead of declaring yet another variable.

We could also set ptr2 here... Allowing to avoid the diff from here to....

here - making the commit all the more explicit (for me this commit is 
basically only renaming a variable, since unmap_system doesn't appear in 
the git context) - by only changing:

unmap_system(buf1);
unmap_system(buf2);

to

unmap_system(base);
unmap_system(ptr2);

I believe?

Additionally, my linter tells me that:

buf1 += size;
buf2 += size;

is undefined behavior:

arithOperationsOnVoidPointer: 'buf1' is of type 'const void *'. When 
using void pointers in calculations, the behaviour is undefined.

I suggest the following:

buf1 = ((u8 *)buf1) + size;
buf2 = ((u8 *)buf2) + size;

since size seems to be size in bytes?

What do you think?

We already have test/cmd/mem.c is this something we can augment to test 
the unmapping is proper too?

Cheers,
Quentin

Hmmm I thought that got changed...or at least I rely on void * being
taken as char * when diffing pointers.

Well I think you should send a patch! It seems reasonable to me.

Yes, it would be possible to check the list of mapped pointers in
sandbox, to make sure it has gone back to its original state (i.e. any
new mappings in the test were deleted before the test ended).

[PATCH v4 20/23] test: mbr: Unmap the buffers after use

[Simon Glass]

This tests maps some local variables into sandbox's address space. Make
sure to unmap them afterwards.

Note that the normal approach with sandbox is to use a fixed memory
address in the RAM, to avoid needing to create a map for transient local
variables.

[PATCH v4 21/23] test: mbr: Use a constant for the block size

[Simon Glass]

It isn't that important to factor out constants in tests, but in this
case we have 0x200 and 512 used. The commands don't use the constant
as they use a block count ('1'). It doesn't create more code to use a
constant, so create one.

[PATCH v4 22/23] test: mbr: Use RAM for the buffers

[Simon Glass]

The normal approach with sandbox is to use a fixed memory address in the
RAM, to avoid needing to create a map for transient local variables.

Update this test to use this approach.

[PATCH v4 23/23] test: mbr: Drop a duplicate test

[Simon Glass]

The test currently runs twice as it is declared twice. Unwind this.

Signed-off-by: Simon Glass <sjg@chromium.org>
---

Changes in v4:
- Rebase to -next (on top of testc series)
- Drop patch to add UT_TESTF_CONSOLE_REC to bootflow tests

Changes in v2:
- Add many new patches to resolve all the outstanding test issues
