hil/parisc: Disable HIL driver when it gets stuck

2020-10-22T20:44:35+00:00

When starting a HP machine with HIL driver but without an HIL keyboard or HIL mouse attached, it may happen that data written to the HIL loop gets stuck (e.g. because the transaction queue is full). Usually one will then have to reboot the machine because all you see is and endless output of: Transaction add failed: transaction already queued? In the higher layers hp_sdc_enqueue_transaction() is called to queued up a HIL packet. This function returns an error code, and this patch adds the necessary checks for this return code and disables the HIL driver if further packets can't be sent. Tested on a HP 730 and a HP 715/64 machine. Signed-off-by: Helge Deller Cc:

Input: hil_mlc - convert timeval to jiffies

2018-01-02T05:39:12+00:00

struct timeval is not y2038 safe, and what mlc->instart do is scheduling a task in a fixed timeout, so jiffies is the simplest choice here. In hilse_donode(), the expires in mod_timer equals jiffies + intimeout - (now - instart) If we use jiffies in 'now', the expires equals instart + intimeout So, all we need to do is that making sure expires is a future timestamp before passed it to mod_timer.

Input: hil_mlc - convert timeval to time64_t

2018-01-02T05:39:12+00:00

Since mlc->lcv_t is only interested in seconds, directly using time64_t here. This gets rid of the deprecated do_gettimeofday() and avoids problems with time going backwards since we now use the monotonic clocksource.

[PARISC] Update parisc specific input code from parisc tree

2005-10-22T02:58:51+00:00

Update drivers to new input layer changes. Signed-off-by: Helge Deller Signed-off-by: Matthew Wilcox Reorder code in gscps2_interrupt() and only enable ports when opened. This fixes issues with hangs booting an SMP kernel on my C360. Previously serio_interrupt() could be called before the lock in struct serio was initialised.
