ACER TRAVELMATE P648-MG NXP NFC DRIVER
Acer TravelMate PG2 (i7, GB) Laptop Review - Reviews
The main reason is that the original CBS was not designed for such sort of tasks. One problem reported by Xunlei Pang takes place when a task suspends, and then is awakened before the deadline, but so close to the deadline that its remaining runtime can cause the task to have an absolute density higher than allowed.
In such situation, the original CBS assumes that the task is facing an early activation, and so it replenishes the task and set another deadline, one deadline in the future. This rule works fine for implicit deadline tasks. Moreover, it allows the system to adapt the period of a task in which the external event source suffered from a clock drift.
However, this opens the window for bandwidth leakage for constrained deadline tasks. For instance, a task with the following parameters: In Acer TravelMate P648-MG NXP NFC case, the original CBS would assume the task had an early wakeup. Then, CBS will reset the runtime, and the absolute deadline will be postponed by one relative deadline, allowing the task to run. The problem is that, if the task runs this pattern forever, it will keep receiving bandwidth, being able to run 1ms every 2ms.
Following this behavior, the task would be able to run ms in 1 sec. A revised version of the idea is: At a given time Acer TravelMate P648-MG NXP NFC, the maximum absolute density of a task cannot be higher than its relative density, that is: It is note worthy that the laxity cannot be negative because that would cause a negative runtime. Thus, this patch depends on the patch: Throttle a constrained deadline task activated after the deadline" Which throttles a constrained deadline task activated after the deadline. Finally, it is also possible to use the revised wakeup rule for all other tasks, but that would require some more discussions about pros and cons. This is done by a CBS wake up rule.
Use the revised wakeup rule for suspending constrained dl tasks Sasha Levin 0: Split LCD mux and gpio 0: This will fail for the pinmux group, but doesn't cause any harm, as the failure is ignored silently. Error applying setting, reverse things back sh-pfc e Add pinctrl and gpio-hog for lcdc0" Signed-off-by: Miller, Sasha Levin From: Russell Senior provided steps to reproduce the issue: Disconnect ethernet cable, apply power, wait until device Acer TravelMate P648-MG NXP NFC booted, plug in ethernet, check for interfaces, no eth0 is listed.
This appears to be a problem during probing of the AR Phy chip. When ethernet has no link, the phy detection fails, and eth0 is not created.
Plugging ethernet later has no effect, because there is no interface as far as the kernel is concerned. The relevant part of the boot log looks like this: As a result, the emac driver bails out early and the user left with no ethernet.
In order to stay compatible with existing configurations, the driver tries the current reset approach at first. This package contains the files needed for installing the NFC driver.
