* ltq-vdsl-mei: add locking to interrupt handlerJan Hoffmann2022-06-071-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some users noticed repeated resyncs at random intervals, which go away when the MEI driver is configured to use polling instead of interrupts. Debugging shows that this seems to be caused by concurrent calls to MEI_ReadMailbox (in the interrupt handler) and MEI_WriteMailbox. This appears to be mostly triggered when there is an interrupt for vectoring error reports. In polling mode, calls to MEI_ReadMailbox are protected by the same semaphore as is used in MEI_WriteMailbox. When interrupts are used, MEI_WriteMailbox appears to rely on MEI_DisableDeviceInt and MEI_EnableDeviceInt to provide mutual exclusion with the interrupt handler. These functions mask/unmask interrupts, and there is an additional check of the mask in the interrupt handler itself. However, this is not sufficient on systems with SMP, as the interrupt handler may be running in parallel, and could already be past the interrupt mask check at this point. This adds a lock to the interrupt handler, and also acquires this lock in MEI_DisableDeviceInt. This should make sure that after a call to MEI_DisableDeviceInt the interrupt is masked, and the interrupt handler is either not running, has alread finished its work, or is still before the interrupt mask check, and is thus going to detect the change.

* ltq-vdsl-mei: enable vectoring error sample callbackJan Hoffmann2022-06-071-11/+0
| | | | | | | | | This re-enables the vectoring error sample callback and adds a dependency to the corresponding driver. Tested-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Jan Hoffmann <jan@3e8.eu> (cherry picked from commit 93f0e1f922ec1351d429259db942f10147e624ff)
* ltq-vdsl-mei: Remove static linkingHauke Mehrtens2022-01-211-0/+47
| | | | | | | | | This removes -static compile option. The -static option tells GCC to link this statically with the libc, which we do not want in OpenWrt. We want to link everything dynamically to the libc. This fixes a compile problem with glibc. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* lantiq: ltq-vdsl-mei: add kernel 5.10 compatiblityMathias Kresin2021-04-122-7/+71

* ltq-vdsl-mei: reset g_tx_link_rate on showtime exitMartin Schiller2018-06-091-0/+12
| | | | | | | | | | | | Without this change, ifx_mei_atm_showtime_check() will always return "showtime" after one call of MEI_InternalXtmSwhowtimeEntrySignal() was done, even if MEI_InternalXtmSwhowtimeExitSignal() was called in the meantime. The ifx_mei_atm_showtime_check() function is used by the ltq-atm and ltq-ptm driver. Signed-off-by: Martin Schiller <ms@dev.tdt.de>
