2022-07-16clocksource/drivers/timer-microchip-pit64b: Use mchp_pit64b_{suspend, resume}Claudiu Beznea1-19/+5
Use mchp_pit64b_suspend() and mchp_pit64b_resume() to disable or enable timers clocks on init and remove specific clk_prepare_{disable, enable} calls. This is ok also for clockevent timer as proper clock enable, disable is done on .set_state_oneshot, .set_state_periodic, .set_state_shutdown calls.

Remove suspend and resume ops for clockevent and add set_state_oneshot() instead. Along with this mchp_pit64b_{suspend, resume}() were called on proper function to disable/enable clocks. This will allow disabling clocks for clockevent in case it is not selected as active clockevent.

2022-07-16clocksource/drivers/timer-mediatek: Implement CPUXGPT timersAngeloGioacchino Del Regno1-0/+114
Some MediaTek platforms with a buggy TrustZone ATF firmware will not initialize the AArch64 System Timer correctly: in these cases, the System Timer address is correctly programmed, as well as the CNTFRQ_EL0 register (reading 13MHz, as it should be), but the assigned hardware timers are never started before (or after) booting Linux. In this condition, any call to function get_cycles() will be returning zero, as CNTVCT_EL0 will always read zero. One common critical symptom of that is trying to use the udelay() function (calling __delay()), which executes the following loop: start = get_cycles(); while ((get_cycles() - start) < cycles) cpu_relax(); which, when CNTVCT_EL0 always reads zero, translates to: while((0 - 0) < 0) ==> while(0 < 0) ... generating an infinite loop, even though zero is never less than zero, but always equal to it (this has to be researched, but it's out of the scope of this commit). To fix this issue on the affected MediaTek platforms, the solution is to simply start the timers that are designed to be System Timer(s). These timers, downstream, are called "CPUXGPT" and there is one timer per CPU core; luckily, it is not necessary to set a start bit on each CPUX General Purpose Timer, but it's conveniently enough to: - Set the clock divider (input = 26MHz, divider = 2, output = 13MHz); - Set the ENABLE bit on a global register (starts all CPUX timers). The only small hurdle with this setup is that it's all done through the MCUSYS wrapper, where it is needed, for each read or write, to select a register address (by writing it to an index register) and then to perform any R/W on a "CON" register. For example, writing "0x1" to the CPUXGPT register offset 0x4: - Write 0x4 to mcusys INDEX register - Write 0x1 to mcusys CON register Reading from CPUXGPT register offset 0x4: - Write 0x4 to mcusys INDEX register - Read mcusys CON register. Finally, starting this timer makes platforms affected by this issue to work correctly.

2022-05-18clocksource/drivers/sp804: Avoid error on multiple instancesAndre Przywara1-5/+5
When a machine sports more than one SP804 timer instance, we only bring up the first one, since multiple timers of the same kind are not useful to Linux. As this is intentional behaviour, we should not return an error message, as we do today: =============== [ 0.000800] Failed to initialize '/bus@8000000/motherboard-bus@8000000/iofpga-bus@300000000/timer@120000': -22 =============== Replace the -EINVAL return with a debug message and return 0 instead. Also we do not reach the init function anymore if the DT node is disabled (as this is now handled by OF_DECLARE), so remove the explicit check for that case. This fixes a long standing bogus error when booting ARM's fastmodels.

2022-04-08RDMA/hfi1: Fix use-after-free bug for mm structDouglas Miller1-0/+6
Under certain conditions, such as MPI_Abort, the hfi1 cleanup code may represent the last reference held on the task mm. hfi1_mmu_rb_unregister() then drops the last reference and the mm is freed before the final use in hfi1_release_user_pages(). A new task may allocate the mm structure while it is still being used, resulting in problems. One manifestation is corruption of the mmap_sem counter leading to a hang in down_write(). Another is corruption of an mm struct that is in use by another task.

2022-04-08iommu/omap: Fix regression in probe for NULL pointer dereferenceTony Lindgren1-1/+1
Commit 3f6634d997db ("iommu: Use right way to retrieve iommu_ops") started triggering a NULL pointer dereference for some omap variants: __iommu_probe_device from probe_iommu_group+0x2c/0x38 probe_iommu_group from bus_for_each_dev+0x74/0xbc bus_for_each_dev from bus_iommu_probe+0x34/0x2e8 bus_iommu_probe from bus_set_iommu+0x80/0xc8 bus_set_iommu from omap_iommu_init+0x88/0xcc omap_iommu_init from do_one_initcall+0x44/0x24 This is caused by omap iommu probe returning 0 instead of ERR_PTR(-ENODEV) as noted by Jason Gunthorpe <jgg@ziepe.ca>. Looks like the regression already happened with an earlier commit 6785eb9105e3 ("iommu/omap: Convert to probe/release_device() call-backs") that changed the function return type and missed converting one place.
