Hi list,
Maybe some simple questions, but I do not find good answers from google.
The timer is setup in sdhci_add_host, and modified to 10s later in
sdhci_send_command.
1. This timer seems to bu used to indicate that host controller does not
send IRQ to the cpu core(ex. ARM) after 10s since sdhci_send_command. Am
I right?
2. Why is 10s? Isn't it too long? User space applications may produce
large MMC requests to the MMC queue.
Also, cancle the requests will waste much time. The user may think
the device is dead.
Thanks.
Ryan
