2020-12-30soc: qcom: smp2p: Safely acquire spinlock without IRQsEvan Green1-2/+3
commit fc3e62e25c3896855b7c3d72df19ca6be3459c9f upstream. smp2p_update_bits() should disable interrupts when it acquires its spinlock. This is important because without the _irqsave, a priority inversion can occur. This function is called both with interrupts enabled in qcom_q6v5_request_stop(), and with interrupts disabled in ipa_smp2p_panic_notifier(). IRQ handling of spinlocks should be consistent to avoid the panic notifier deadlocking because it's sitting on the thread that's already got the lock via _request_stop(). Found via lockdep.

[ Upstream commit b4fa73358c306d747a2200aec6f7acb97e5750e6 ] The patch fix two reference leak. 1) pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to call put operation will result in reference leak. 2) The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced. We fix it by: 1) adding call pm_runtime_put_noidle or pm_runtime_put_sync in error handling. 2) adding pm_runtime_disable in error handling, to keep usage counter and disable depth balanced.

2020-12-30soc: qcom: geni: More properly switch to DMA modeDouglas Anderson1-2/+15
[ Upstream commit 4b6ea87be44ef34732846fc71e44c41125f0c4fa ] On geni-i2c transfers using DMA, it was seen that if you program the command (I2C_READ) before calling geni_se_rx_dma_prep() that it could cause interrupts to fire. If we get unlucky, these interrupts can just keep firing (and not be handled) blocking further progress and hanging the system. In commit 02b9aec59243 ("i2c: i2c-qcom-geni: Fix DMA transfer race") we avoided that by making sure we didn't program the command until after geni_se_rx_dma_prep() was called. While that avoided the problems, it also turns out to be invalid. At least in the TX case we started seeing sporadic corrupted transfers. This is easily seen by adding an msleep() between the DMA prep and the writing of the command, which makes the problem worse. That means we need to revert that commit and find another way to fix the bogus IRQs. Specifically, after reverting commit 02b9aec59243 ("i2c: i2c-qcom-geni: Fix DMA transfer race"), I put some traces in. I found that the when the interrupts were firing like crazy: - "m_stat" had bits for M_RX_IRQ_EN, M_RX_FIFO_WATERMARK_EN set. - "dma" was set. Further debugging showed that I could make the problem happen more reliably by adding an "msleep(1)" any time after geni_se_setup_m_cmd() ran up until geni_se_rx_dma_prep() programmed the length. A rather simple fix is to change geni_se_select_dma_mode() so it's a true inverse of geni_se_select_fifo_mode() and disables all the FIFO related interrupts. Now the problematic interrupts can't fire and we can program things in the correct order without worrying. As part of this, let's also change the writel_relaxed() in the prepare function to a writel() so that our DMA is guaranteed to be prepared now that we can't rely on geni_se_setup_m_cmd()'s writel(). NOTE: the only current user of GENI_SE_DMA in mainline is i2c.

2020-10-10soc/tegra: pmc: Don't create fake interrupt hierarchy levelsMarc Zyngier1-48/+7
The Tegra PMC driver does ungodly things with the interrupt hierarchy, repeatedly corrupting it by pulling hwirq numbers out of thin air, overriding existing IRQ mappings and changing the handling flow of unsuspecting users. All of this is done in the name of preserving the interrupt hierarchy even when these levels do not exist in the HW. Together with the use of proper IRQs for IPIs, this leads to an unbootable system as the rescheduling IPI gets repeatedly repurposed for random drivers... Instead, let's simply mark the level from which the hierarchy does not make sense for the HW, and let the core code trim the usused levels from the hierarchy.
