* linux: Add noide and noahci kernel optionsSamuel Thibault2024-01-231-1/+4
| | | | | They were meant to be temporary, but that got longer, and people seem to expect them to be there now.
* linux: Skip probing IDE when 255 phys heads detectedDamien Zammit2023-02-011-1/+1
| | | | | This allows qemu -M q35 to boot without 30 second timeout failing on hd0, when disk is actually attached via ahci.
* Drop spurious changesSamuel Thibault2022-12-221-4/+1
|
* Warn only once about not being able to recycle pagesSamuel Thibault2022-12-221-1/+4

| | | | | | | | | | * linux/dev/drivers/block/ahci.c (ahci_do_port_request): Reject sectors beyond LBA48 or LBA28. * linux/dev/glue/block.c (check_rw_block): New function. (rdwr_partial, rdwr_full): Use check_rw_block to reject block number overflows. * linux/src/drivers/block/ide.c (do_rw_disk): Reject sectors beyond LBA28 or CHS.
* simplify interrupt handlingDamien Zammit2019-11-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have removed spl levels, now remove the machinery to manage different PIC masks according to levels. Only keep machinery to disable interrupts whatever the level. * i386/i386/pic.c (pic_mask): Remove array. (picinit): Do not form PIC mask. Set initial PIC mask to 0. (form_pic_mask): Remove function. * i386/i386/pic.h (form_pic_mask, pic_mask): Remove declarations. * i386/i386/spl.S (SETMASK): Remove macro.

* ide: Use default IRQ by defaultSamuel Thibault2019-11-101-0/+1
| | | | | | | | To avoid even trying to probe IRQs. Nowadays' hardware use the default IRQ anyway. * linux/src/drivers/block/ide.c (init_hwif_data): Set hwif->irq to default_irqs[index].
* Keep DMA enabled on QEMU disksSamuel Thibault2018-06-131-0/+8
| | | | | | | | When the host is very loaded, some requests might time out, but that is not a reason for disabling DMA, so keep it enabled. * linux/src/drivers/block/triton.c (config_drive_for_dma): When disk is QEMU, set using_dma and keep_settings to 1.

| | | | | | | | | | | Some very slow qemu instances would eventually trigger DMA timeouts, let's give a way to disable DMA there, it does not actually slow down operations anyway. * linux/src/drivers/block/ide.h (ide_drive_s): Add nodma field. * linux/src/drivers/block/ide.c (do_identify): Do not call dmaproc(ide_dma_check) when nodma is 1.

* ide: Increase WAIT_DRQ to accomodate some CF cards and SSD drives.David S. Miller2012-12-211-1/+2
| | | | | | | | | | | | | Based upon a patch by Philippe De Muyter, and feedback from Mark Lord and Robert Hancock. As noted by Mark Lord, the outdated ATA1 spec specifies a 20msec timeout for setting DRQ but lots of common devices overshoot this. Signed-off-by: David S.
