2023-10-09dmaengine: pxa_dma: Remove an erroneous BUG_ON() in pxad_free_desc()Christophe JAILLET
If pxad_alloc_desc() fails on the first dma_pool_alloc() call, then sw_desc->nb_desc is zero. In such a case pxad_free_desc() is called and it will BUG_ON(). Remove this erroneous BUG_ON(). It is also useless, because if "sw_desc->nb_desc == 0", then, on the first iteration of the for loop, i is -1 and the loop will not be executed. (both i and sw_desc->nb_desc are 'int') Fixes: a57e16cf0333 ("dmaengine: pxa: add pxa dmaengine driver") Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/c8fc5563c9593c914fde41f0f7d1489a21b45a9a.1696676782.git.christophe.jaillet@wanadoo.fr Signed-off-by: Vinod Koul <vkoul@kernel.org>

2023-10-04dmaengine: mediatek: Fix deadlock caused by synchronize_irq()Duoming Zhou
The synchronize_irq(c->irq) will not return until the IRQ handler mtk_uart_apdma_irq_handler() is completed. If the synchronize_irq() holds a spin_lock and waits the IRQ handler to complete, but the IRQ handler also needs the same spin_lock. The deadlock will happen. The process is shown below: cpu0 cpu1 mtk_uart_apdma_device_pause() | mtk_uart_apdma_irq_handler() spin_lock_irqsave() | | spin_lock_irqsave() //hold the lock to wait | synchronize_irq() | This patch reorders the synchronize_irq(c->irq) outside the spin_lock in order to mitigate the bug.

The k3_udma_glue_tx_get_irq() function currently returns negative error codes on error, zero on error and positive values for success. This complicates life for the callers who need to propagate the error code.

2023-10-04dmaengine: idxd: use spin_lock_irqsave before wait_event_lock_irqRex Zhang
In idxd_cmd_exec(), wait_event_lock_irq() explicitly calls spin_unlock_irq()/spin_lock_irq(). If the interrupt is on before entering wait_event_lock_irq(), it will become off status after wait_event_lock_irq() is called. Later, wait_for_completion() may go to sleep but irq is disabled. The scenario is warned in might_sleep(). Fix it by using spin_lock_irqsave() instead of the primitive spin_lock() to save the irq status before entering wait_event_lock_irq() and using spin_unlock_irqrestore() instead of the primitive spin_unlock() to restore the irq status before entering wait_for_completion(). Before the change: idxd_cmd_exec() { interrupt is on spin_lock() // interrupt is on wait_event_lock_irq() spin_unlock_irq() // interrupt is enabled ... spin_lock_irq() // interrupt is disabled spin_unlock() // interrupt is still disabled wait_for_completion() // report "BUG: sleeping function // called from invalid context... // in_atomic() irqs_disabled()" } After applying spin_lock_irqsave(): idxd_cmd_exec() { interrupt is on spin_lock_irqsave() // save the on state // interrupt is disabled wait_event_lock_irq() spin_unlock_irq() // interrupt is enabled ... spin_lock_irq() // interrupt is disabled spin_unlock_irqrestore() // interrupt is restored to on wait_for_completion() // No Call trace } Fixes: f9f4082dbc56 ("dmaengine: idxd: remove interrupt disable for cmd_lock") Signed-off-by: Rex Zhang <rex.zhang@intel.com> Signed-off-by: Lijun Pan <lijun.pan@intel.com> Reviewed-by: Dave Jiang <dave.jiang@intel.com> Reviewed-by: Fenghua Yu <fenghua.yu@intel.com> Link: https://lore.kernel.org/r/20230916060619.3744220-1-rex.zhang@intel.com Signed-off-by: Vinod Koul <vkoul@kernel.org>

CHn_MUX must have a unique value when selecting a peripheral slot in the channel mux configuration. The only value that may overlap is source 0.

Commit e39a2329cfb09 ("Kconfig: Allow k3dma driver to be selected for more then HISI3xx platforms") expanded the "depends on" line of K3_DMA from "ARCH_HI3xxx" to "ARCH_HI3xxx || ARCH_HISI || COMPILE_TEST". However, ARCH_HI3xxx implies ARCH_HISI, so it's unnecessary to list both. Instead, just list ARCH_HISI, which covers all HiSilicon platforms.

2023-09-28dmaengine: idxd: Register dsa_bus_type before registering idxd sub-driversFenghua Yu
idxd sub-drivers belong to bus dsa_bus_type. Thus, dsa_bus_type must be registered in dsa bus init before idxd drivers can be registered. But the order is wrong when both idxd and idxd_bus are builtin drivers. In this case, idxd driver is compiled and linked before idxd_bus driver. Since the initcall order is determined by the link order, idxd sub-drivers are registered in idxd initcall before dsa_bus_type is registered in idxd_bus initcall. idxd initcall fails: [ 21.562803] calling idxd_init_module+0x0/0x110 @ 1 [ 21.570761] Driver 'idxd' was unable to register with bus_type 'dsa' because the bus was not initialized. [ 21.586475] initcall idxd_init_module+0x0/0x110 returned -22 after 15717 usecs [ 21.597178] calling dsa_bus_init+0x0/0x20 @ 1 To fix the issue, compile and link idxd_bus driver before idxd driver to ensure the right registration order.

void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() is renamed to .remove().
