7 years agousb: dwc3: gadget: make cache-maintenance on event buffers more robust
Philipp Tomsich [Thu, 6 Apr 2017 14:58:53 +0000 (16:58 +0200)]
usb: dwc3: gadget: make cache-maintenance on event buffers more robust

Merely using dma_alloc_coherent does not ensure that there is no stale
data left in the caches for the allocated DMA buffer (i.e. that the
affected cacheline may still be dirty).

The original code was doing the following (on AArch64, which
translates a 'flush' into a 'clean + invalidate'):
  # during initialisation:
      1. allocate buffers via memalign
        => buffers may still be modified (cached, dirty)
  # during interrupt processing
      2. clean + invalidate buffers
        => may commit stale data from a modified cacheline
      3. read from buffers

This could lead to garbage info being written to buffers before
reading them during even-processing.

To make the event processing more robust, we use the following sequence
for the cache-maintenance:
  # during initialisation:
      1. allocate buffers via memalign
      2. clean + invalidate buffers
        (we only need the 'invalidate' part, but dwc3_flush_cache()
  always performs a 'clean + invalidate')
  # during interrupt processing
      3. read the buffers
        (we know these lines are not cached, due to the previous
  invalidation and no other code touching them in-between)
      4. clean + invalidate buffers
        => writes back any modification we may have made during event
    processing and ensures that the lines are not in the cache
    the next time we enter interrupt processing

Note that with the original sequence, we observe reproducible
(depending on the cache state: i.e. running dhcp/usb start before will
upset caches to get us around this) issues in the event processing (a
fatal synchronous abort in dwc3_gadget_uboot_handle_interrupt on the
first time interrupt handling is invoked) when running USB mass
storage emulation on our RK3399-Q7 with data-caches on.

tiny-printf: Add support for %p format

Add support for %p, %pa[p], %pM, %pm and %pI4 formats to tiny-printf.
%pM and %pI4 are widely used by SPL networking stack and is required if
networking support is desired in SPL.
%p, %pa and %pap are mostly used by debug prints and hence supported
only when DEBUG is enabled.

Before this patch:
$ size spl/u-boot-spl
   text    data     bss     dec     hex filename
  99325    4899  218584  322808   4ecf8 spl/u-boot-spl

$ size spl/u-boot-spl
   text    data     bss     dec     hex filename
  99666    4899  218584  323149   4ee4d spl/u-boot-spl

So, this patch adds ~350 bytes to code size.

If CONFIG_SPL_NET_SUPPORT is not enabled, this adds ~25 bytes.

If CONFIG_USE_TINY_PRINTF is disabled then:
$ size spl/u-boot-spl
  text    data     bss     dec     hex filename
 101116    4899  218584  324599   4f3f7 spl/u-boot-spl

So, there is still ~1.4K space saved even with support for %pM/%pI4.

Compiler used is to build is:

buffers are never freed. This becomes quite nasty using the fw_ tools as
library, because each access to the environment (even just reading a

Fix this renaming fw_env_close() as fw_env_flush(), because the function
really flushes the environment from RAM to storage, and add a
fw_env_close function to free the allocated resources.
