On some old MAC chips without COE sometime the Transmit Underflow error is issued. The driver aborted all the transmission process and initialized it from scratch. This breaks the network activity as raised by Nachiketa on a SPEAr board. The patch is to fix this rare underflow event. The driver will only clear the interrupt and the Tx DMA will go out the Suspend state as soon as the descriptor is fetched again. The driver will continue to bump-up the DMA FIFO threshold that, indeed, helped somebody to prevent this kind of error in the past as well.

由 Linus Torvalds 提交于
In commit 13583b16 ("PCI: refactor io size calculation code") Ram had a thinko in the refactorization of the code: the end result used the variable 'align' for the bus alignment, but the original code used 'min_align'. Since then, another use of that 'align' variable got introduced by commit c8adf9a3 ("PCI: pre-allocate additional resources to devices only after successful allocation of essential resources.") Fix both of those uses to use 'min_align' as they should.

This patch fixes a very serious off-by-one bug in the driver, which could leave the device in an unresponsive state. The problem was that the extra_len variable [used to reserve extra scratch buffer space for the firmware] was left uninitialized. Because p54_assign_address later needs the value to reserve additional space, the resulting frame could be to big for the small device's memory window and everything would immediately come to a grinding halt.

Commit f44f7f96 ("RTC: Initialize kernel state from RTC") caused a boot regression on the MRST platform. The reason is that rtc_device_register() calls rtc_read_alarm() after that change, which function does not have all driver data set up yet. The rtc-mrst driver needs to call dev_set_drvdata() before rtc_device_register() gets called.

When an interrupt occurs, the INT pin is driven low by the MCP251x controller (falling edge) but in some cases the INT pin can be connected to the MPU through a transistor or level translator which inverts this signal.

The current block integrity (DIF/DIX) support in DM is verifying that all devices' integrity profiles match during DM device resume (which is past the point of no return). To some degree that is unavoidable (stacked DM devices force this late checking). But for most DM devices (which aren't stacking on other DM devices) the ideal time to verify all integrity profiles match is during table load. Introduce the notion of an "initialized" integrity profile: a profile that was blk_integrity_register()'d with a non-NULL 'blk_integrity' template. Add blk_integrity_is_initialized() to allow checking if a profile was initialized. Update DM integrity support to: - check all devices with _initialized_ integrity profiles match during table load; uninitialized profiles (e.g. for underlying DM device(s) of a stacked DM device) are ignored. - disallow a table load that would result in an integrity profile that conflicts with a DM device's existing (in-use) integrity profile - avoid clearing an existing integrity profile - validate all integrity profiles match during resume; but if they don't all we can do is report the mismatch (during resume we're past the point of no return) Signed-off-by: NMike Snitzer <snitzer@redhat.com> Cc: Martin K.
